ORGANIC LECTURE & LAB STUDENTS SPRING 2016:   (scroll down to Large Font "SIU Organic Lecture & Lab Information" Hyperlink to get to posted links) 

(posted OC I worksheet answer key on  5/5)  posted OCI & OCII notes 5/2 & 5/4) (posted Final Exam with common points for common mistakes for Organic I Lab and Organic II Lab)


Organic Chemistry I Lecture (CHEM 340) Final Grades  Spring 16        Organic Chemistry II Lecture (CHEM 442) Final Grades Spring 16    Here are all of your grades showing every single last points as promised.   If you gave me the signed "permission to post form", your grades are posted.    posted by Dr. Hahn 5/20/16   Organic Chemistry I Lecture Final Exam Key with points for common mistakes.   Organic Chemistry II Lecture Final Exam Key with points for common mistakes.

Organic Chemistry I Lab (CHEM 341) Final Grades Spring 16         Organic Chemistry II Lab (CHEM 443) Final Grades Spring 16   Here are all of our grades showing every single las point as promised.    If you gave me the signed "permission to post form" your grades are posted.   Note:   Your lab report grades are from your TA.   I did not make up lab report grades which were not supplied to me by excel spread sheet by email.   I have documented proof of what grades were supplied by your TA - I am not making stuff up/deleting off grades which your TA gave me.   Unless your TA submitted a change of grade, the grades are as posted.    posted by Dr. Hahn 5/20/16 Friday at 4:15 pm from her Carbondale Apartment 

(correction to statement of 5/20/16- I read my own posting and noticed that it sounds a little different than my intended statement:    I was very busy and barely managed to post the above.   In the above statement "...Unless your TA submitted a change of grade, the grades are as posted...."   Since I am the primary instructor of record for these classes, your TA should not be able to submit a change of grade form by themselves.    What I meant to say is that unless your TA emailed me a grade change - because they for instance found your lab report which they had previously not reported to me, or because they felt like changing your grade for some unknown reason and emailed me that they had made an error in the grades which they had emailed me before and in writing admitted to  their own mistakes.    I stand behind the lab report grades which I posted as being exactly what your TA submitted for your lab report grade and I have documentation to support that I posted the grades that the TAs submitted to me.  I would of course have no possible reason to change or make up grades which the TAs did not submit to me.    posted by Dr. Hahn 5/26/16 Thursday at 8 am from her Carbondale apartment)


Final grading at Carbondale Apartment by myself:   Grades are due at 8 am on May 18 Wednesday.    This is ~ 200 x 12 page x 2/3 not multiple choice exams.   The classroom is a little too small for students to sit in alternate seats so I have 3 rows with students sitting elbow to elbow (18 students per row) and then the rest of the remaining 8 rows with alternate seats of 9 students per row for the Organic II Lecture class.   (That is why the OCII class exams has 2 colors green & white in this case.)   The Organic I lecture class is small enough so that I could spread out the students in alternate seats so there is only one color exam.    Usually takes about a week to grade that many exams.    Had only from May 13 at 2:30 pm until May 18 at 8 am to grade the last 120 of the exams.  

In front are the excel spread sheets.   So that is forOCII Lecture = 120 students x {6 quizzes (manuallly drop 2 lowest quiz grades) + 3 exams (replace lowest exam grade by final exam grade manually) + some ~40 clicker days} = 5880 individual grades for OCII, OCI Lecture = 70 students x (6 + 3+ 40) = 3430 individual grades    for the OCII Lab:   90 students x (6 lab report grades + 6 clicker quizzes + midterm + final ) = 1260 individual grades, for the OCI Lab:   70 students x (9 lab report grades +9 clicker quizzes + midterm+final exam) = 1400 individual grades.    Drop lowest grades manually:   drop one of the lab report grades, drop one lowest quiz grade, give highest of 10% lower of midterm or final exam manually.    = total of 11,970 grades to keep track of for ~360 individual students on roster.

Worked from around 6:30 am until around 11:30 pm since Friday 5/13 until now.   I stopped grading when I got too sleepy to continue to grade.   If I continue to grade when sleepy, I would make grading errors.

A student asked that they see their final exam BEFORE I submitted their final grades.    So to be fair, I should offer to meet all 200 Organic Chemistry Lecture students to view their graded final exam BEFORE I submit their final grades.  Final exam period is over.  New semester starts  about a month later.  Usually the university locks building doors and does not turn on building lights during parts of intercession.   I am NOT going to meet with a few students BEFORE I submit their final grades.   It would give the appearance of improprierity.  I don't think I know a single professor who does that routinely with 200 students or even with 5 students.    It is unfair.    You grade the hardcopy paper.    You do not have a conversation with a student telling you what grade they need in order to achieve their dreams while you grade and adjust your grade depending on how compelling a student's vision of their dream future is.      If 200 students come to look at their final exam, I would have no final grades ready by the grading deadline.   posted by Dr. Hahn at 7:50 am 5/17/16 while grading exams  barely eating and barely sleeping for about a week - my mom is worried that I will get sick from all the work - I may drop dead of a heart attack from all the stressful work.


The reason that I do not post your grades on D2L is:  (I post the excel spreadsheet that I will use to calculate your final grades instead regularly.)  (a) I want you to see how everyone else in the class is doing so that you have perspective.   I also am transparent about your grades.   I do not play around with your grades.   You will earn exactly what you earn.   I am not going to give one student with an 88% an A and another students with an 88% a B.     (b) Another issue with D2L with a lot of students with multiple people able to enter grades (such as multiple teaching assistants and myself), if someone accidentally changes a student's grade (perhaps with a similar name) lets say from a 60% to 90%, I really cannot keep track of the error with the 160 Organic Chemistry I lab and Organic Chemistry II lab students in 9 lab sections with 6 teaching assistants.     I really cannot keep track of errors with the around 190 total students in the Organic Lecture sections (120 students in Organic II Lecture, 70 students in Organic I Lecture).   I have multiple excel spreadsheets and I keep hardcopies of all excel spreadsheets and I regularly post all grades (provided that you submitted a pin number form giving me persmission to post).   That way both you and I can check for errors and make sure that you earn exactly the grade that you earn, nothing more and nothing less.

 The reason why there is a penalty (on the lab syllabus which you all signed)  for turning in lab reports late is that if there is no penalty, some people will hold onto all their lab reports and then try turn them in at the last minute all at once.   People get back graded lab reports weekly so first it is unfair for someone to have access to their friend's graded lab report and then turn in the lab report later.   You may think that you are going to do so much better if you were able to turn things in late but really it does not help at all.   Usually students forget stuff they need in order to do a good lab report if they wait too long to write it up.    There is also the problem of if grades need to be submitted on time at the end of the semester.    If students hold onto their lab reports until after the grades are submitted, I would argue that you are turning in work after the class is over.   How many people let you do that?   No one lets you do that and I am not going to let you do that either.    There is no possibility - ZERO possibility of you turning things in past the deadline and getting me to submit a grade change after grades are submitted.   posted by Dr. Hahn on 4/9/16 Saturday at 9:50 am from her Carbondale Apartment     

The following shows some examples (click on examples) of why you lose points on Chemical Synthesis problems.   It is NOT because I am being mean and picky.  I grade synthesis based on what you write down in the previous step.    As an example the grading for Jane (just an example name - I don't know any Jane) shows that the answer that she wrote down for step C exactly matches the correct answer.   However Jane gets NO POINTS for her step C because there is no way that Jane's step B can undergo reaction with BH3/THF, H2O2, OH- to result in Jane's step C.   On the other hand John gets half credit for his step C even though it does not at all match the correct answer for Step C.   John gets credit for his step C because his incorrect step B does indeed react with BH3/THF, H2O2, OH- to give John's step C.   posted by Dr. Hahn on 3/28/16 Monday at 3:50 pm from her SIU office

The following shows some examples (click on examples) of why you lose points on Chemical Reaction.   It is NOT because I am being mean and picky.   It is because the following things are INCORRECT according to ANY NORMAL Organic Chemist.   A hexagon with a circle inside it (benzene) is NOT the same chemically as a hexagon without a circle inside it (hexane).   Hexane does not react at all like benzene.   You cannot do an electrophilic substitution reaction on hexane.   When you do an oxidation on a primary alcohol, if you move the position of the carbonyl carbon by one measly CH2 group, it is not the same molecule.   Chemically for an organic chemist to put in one more CH2 group takes multi step synthesis.   It is not easy to just put in one more CH2 group in a carbonyl group.  

So if you say then why don't you give partial credit for molecules that are similar to the product so if your answer is just off by one CH2 group why not take off 1/2 points or if you leave the circle out in a benzene molecule why don't you take off half credit.   I really avoid doing that like the plague because when I am grading some 120 of the Organic II Lecture exams and 70 of the Organic I Lecture exams, and I give you a blank space on which you can write anything, people will write almost as many variations of wrong as there are people in the class.   It is almost impossible for me to keep the grading consistent when I give partial credit for incorrect answers on chemical reactions.   I will have a significant number of students who will come and tell me that I took off 1/2 a point more from their exam than I did from their friend's exam.   There might be a small difference between the answers or the answer may indeed be exactly the same with a 1/2 point difference in the grading.   If I was grading 5 exams or even 20 exams, I could line up all the answers and grade consistenly down to the last 1/2 a point but if I am grading a large number of exams, it is almost impossible to do that.  

 So the only way that I can be fair is to just give NO PARTIAL CREDIT on incorrect answers on chemical reactions.

Also let me warn you, if you do not take quizzes and exam with no documentation, I will give you a zero on the missed work.   I am not going to accept flimsy documentation.   If I do I might as well say that everyone can take as few or as many exams as they want and I will just average in the quizzes and exams that you did take.   THAT IS NOT GOING TO HAPPEN.   You all signed the syllabus agreement saying that unless you have a valid documented excuse, that you will earn a zero on the missed work.   

Keep in mind that according to my syllabus, you get to drop TWO of SIX quizzes (with no documentation) and you get to replace ONE missed  EXAM of THREE EXAM with the FINAL EXAM (with no documentation).   So you can miss 1/3 of the semester's work without documentation and not lose any points.   I am not going to quibble with you about a flimsy excuse for missing exams and quizzes on TOP of me letting you drop 1/3 of the semester's work.    You can miss approximately 2 clicker days without penalty in the lecture.   Some universities have a rule that if you miss a week of classes that you automatically earn an F for the semester.   According to that rule, 3 clicker days would earn you an F for the semester and I am letting you drop 2 clicker days without penalty.

In any case if I were you, I would NOT want to try to base the semester's grade on ONE exam or ONE quiz.   The reason why I have multiple quizzes and multiple exams is so that if you mess up ONE exam or ONE quiz, you can take another one and do better.     It is a real gamble to bet that you will do really well on the ONE exam or the ONE quiz that you do take.   

If I accept a flimsy excuse, you do NOT get the class average.   You get your own average prorated with the class average so if you earn a 50% on the ONE exam that you take, then your average prorated for the class average will probably be within a point or two of 50% because the class average does not shift very much from exam to exam.   Plus if you take multiple exams and quizzes, you get more practice and will in general do better on the exams and quizzes.

  Dr. Hahn's Teaching Schedule Prior to Spring 2015



What Am I Doing Now? 


So weird.  In the complex of offices near my office, someone keeps just SLAMMING their door.    It wasn't me.   Then I hear lots of very loud shoes that sounds kind of like my shoes.   Then I see professors walking around in their stocking feet with their very loud shoes off.   Huh ?   What is that all about ?  

posted by Dr. Hahn at 2:02 pm 5/9/16 while making up final exams for my Organic I Lecture and Organic II Lecture while finishing up assembling excel spreadsheets for the Organic I Lab and Organic II Lab.


There are a bunch of faculty office close to my office.  There are also a bunch of Math graduate student offices near my office as well.   I will often get a couple of students who thinks that my office is maybe the Math departmental office.   I also think (from what I am hearing from some students) that I am Mary Kinsel.   I am not sure why.   I am sitting in my office with my name all over my office.   I even walk around with my name on my handbag and some students will see me with my name on my bag and still think that I am Mary Kinsel.   One professor down the hallway made an appointment to meet with a student on Sunday in her office.   She said she was coming in anyway.   My position is strictly teaching.   I get paid to teach and only teach.   I really don't want to do research under some other professor.   I don't want to turn over the research that I was doing in my former faculty positions as principal investigator ( only boss in my own research group) to some other professor.   That would not be in my best interest.  


I can make up exams, grade papers anywhere so I don't come to campus unless classes are in session so on business days and non holidays.   If I wanted to get some graduate student or undergraduate student to help me grade, I could do so but I would never turn over my grading work unless I was absolutley positive that the grading would be handled with utmost integrity and fairness.    A lot of my word problemy kind of exams can have multiple wrong answers that could be correct.   For instance in a synthesis problem if someone answers molecule A wrong but then does the next reaction correctly , the student would get partial credit so it is not just matching the blank so the person grading has to really know the material.   Also there is the problem that if more than one person graded a paper, there would be "strict graders" and "non strict graders".   There is also the problem of if a student is friends with a student whose paper they are grading, even if the grader was trying to be as fair as possible, the grading would be unfair.   


I actually had a student in my Organic II Lecture class in the Fall 2015 semester who volunteered (no pay, no formal appointment) to help me grade Organic I Lecture exams.    She was a postbaccelaureate student who was potentially a chemistry graduate student.   She would often hijack my Organic II Lecture class in long discussions of how I graded her quizzes and exams.    There was no doubt that I had graded her correctly but she would spend my lecture class time and waste the student's time in long discussions about how I was grading her paper.   One time she said that she had  drawn a one mm arrow to one answer but not the other answer and this invisible 1 mm arrow (partially erased) and under some other writing was her indication that her answer was correct.    I would say no it is not correct if I can't see it.    She would say no it is correct.   Why can't you see this 1 mm arrow partially erased and under some other writing.    This discussion went on for some 15 minutes.    I would say no.   She would say yes.


I would never want to have such a person be my grader.   If she thinks an invisible arrow shows the correct answer, the grading would be so horrendous as to be downright non sensical.  Actually it was almost as if she thought that if she critisized my grading ( knowing fully well that she was talking nonsense) that I would ask her to help me grade and that this would somehow lead to some sort of paying grading job.   I suppose it is possible that someone would hire her to grade papers but I would never ask such a person to help me grade my exams.   I could not stand behind the integrity of my grading if I has such a person help me grade even if it was something as silly as adding up points.

Interesting:   This semester I am teaching 4 classes as the primary instructor of record - meaning I am the person who will be submitting the final grades for these 4 classes.   The classes are:   Organic I Lecture (CHEM 340, about 70 students), Organic II Lecture (CHEM 442, about 120 students), Organic I Lab (CHEM 341, about 70 students, 2 graduate teaching assistants) and Organic II Lab (CHEM 443, about 90 students, 4 graduate teaching assistants).   So I see a bunch of teaching evaluation envelopes in my mail box and see only 3.   Two of the envelopes were for the CHEM 442 Lecture the same class.   Apparently the office assistants were told that I am only teaching CHEM 442 and CHEM 340 so that is all they gave me.    So I know I am teaching the CHEM 341 and CHEM 443 ( I meet with the labs students in the prelab class which meets once a week.  I am holding teaching assistant meetings.    I am writing up / modifying lab worksheets and writing up a summary of what they need to do for the lab as the cover sheet for the lab reports but according to the Chemistry department, I am not teaching those classes ?   I am posting spectra and deciding if the students need to do all parts of the labs, etc.   I have not turned over any of my teaching so what is going on ?   


So if I am not teaching those classes and full time teaching says that I must teach those classes then am I getting paid half as much or perhaps out of the goodness of someone's heart they are letting me do only half the work but they are still paying me my full salary ?   I know that I AM teaching all 4 classes.   Teaching those classes is sucking up every little bit of time that I have so that I am barely getting enough sleep and I am now resorting to eating only if it can be heated up in the microwave or stove top for less that 5 minutes.  


Last semester they didn't give me teaching evaluations until Final Exams time.   The office assistants said they put it in my mail box and I didn't know to expect them in my mail box because this was my first semester here last semester.   I know I did not take them out of my mail box until my students asked about evaluations.   So they made up new ones and put them in my mail box very late in the semester.     So teaching evaluation irregularities.      .

It was so odd but I saw bright red cars all over the place this weekend.   I park in the Chemistry parking lot - there is a red car parked next to my car as I leave for the day Friday.    I park at the Walmart to grocery shop.   I see no red cars as I go in but when I come out there is a red car parked next to my car.   I park my car in front of my apartment over the weekend in the coin operated parking meters that they do not give tickets for on the weekends and I see 2 or 3 bright red cars near my car.   My car is a bright red Honda Civic.   It was as if I was seeing myself still there as I left the Chemistry parking lot, the Walmart Parking lot and maybe going somewhere exciting as my car was sitting in front of my apartment parking lot.


Turns out that my apartment is on the SIU bus route.   I can park in front of my apartment from 5 pm to 8 am weekdays without putting money into the meter.   If those few parking spaces are full then I can park on the campus parking lot overnight because I have a faculty parking sticker - I found out that I can even park in commuter student parking spaces with my faculty parking sticker overnight on the university parking lot.  


I have noticed that the bus stop sign is right next to where I normally park my car.   So I am sitting at my desk working on something and I keep noticing this girl who stands on the street side waiting for the bus.about a car length away from the bus stop sign.   She does not stand on the sidewalk  in front of the bus stop sign. like everyone else.    I looked out my window and I see this girl and I thought that she was standing next to my car driver's side door as if she had just gotton out of my car.   She stands around there waiting for the bus for 30 minutes at a time.    I thought to myself now why is thir girl standing next to the driver's door of my parked car in the street instead of standing in front of the bus stop sign about 10 feet away on the sidewalk like everyone else.


This girl stands waiting for the bus it turns out almost every weekday around 5:50 or 6 pm waiting for the crosstown bus that goes to the only mall & Walmart that I am aware of  in town.    I wouldn't do that because why would I not just drive my car to the shopping area and why would I come home at around 5:00 to 5:30 pm from teaching at SIU and then take the bus to go shopping.   I am guessing that maybe she works at the mall ?  Walmart ? is a waitress at some restaurent ?   I remember at one of my other faculty positions this blond waitress who did not look anything like me and lived right above my apartment in a large apartment complex was mistaken for being me.   I don't know why.   We did not look anything alike.   We had nothing in common other than for the fact that she lived right above my apartment with a bunch of girls.    I can imagine someone saying "...  Ah there is Dr. Hahn standing next to her car for 30 minutes waiting for the bus to waitress at the mall after teaching ~200 Organic Chemistry students and 160 Organic Chemistry lab students during the business day ..."

I was sitting in my office, Neckers 255, and I hear a woman's voice out in the hallway loudly saying that "...yes, I am a chemistry professor...."   The woman had no dicernably accent - not foreign - not southern.   (I also have no accent- my accent is sort of Manhattan or upstate NY accent - not Brooklyn or Queens).      Then this voice says "... Yes, I am old....".    So I am sitting in my office and thinking to myself how many female professors are there in chemistry who have no foreign accent and is old.   I don't know anyone like that.   I don't consider myself old so I would never say that I am old.   The only thing that I could think is that perhaps it was some professor who was here before I got here who I have never met ?   I considered running out into the hallway to see who it was but I was doing something like making up an exam and didn't want to leave my laptop unattended so I did not .

PS:   Some people are so opposite of nice that I would not work with them if I was within minutes of dying of thirst and they had the only water source in the entire world and my very life depended on my getting the water from them.  Moral of story, it does not pay to be mean to me.





Still grading at my parent's Columbia, SC home.   Here I am grading the ~130 x 14 page (10 page non multiple choice)  on the front porch of my parent's Columbia, SC home.   If you sit around grading 12 hours a day, you get a little sleepy so I thought I would sit outside to grade.  (The other picture is my parent's house around Christmas 2010 when it snowed. posted by Dr. Hahn at 11:20 am 5/3/15 Sunday from her parent's Columbia, SC home

A question which I keep getting is why did you  decide to go into chemistry ?   Why did you decide to become a Chemistry Professor ?   Do you have children ?


Why did I go into Chemistry ?   I liked Chemistry when I was in high school and in college and I was very good at it.  When my Freshman class in college took an ACS standardized exam, I got the highest grade among all students (~ 200 student class) who took the exam.   I do have to admit that I did take 2 years of Chemistry in high school (one AP Chemistry class) and did not "Advance Place" out of a semester of Introductory Chemistry because I was pretty sure that I wanted to major in it and did not want to have holes in my Introductory Chemistry classes.  (So it is not really that surprising that I got a high standardized exam grade.)   Am I telling you this to make you all into chemistry majors ?   Not really.   Everyone should do what they enjoy doing and what they are good at doing.   Because if you do what you like doing then you will be successful at it and you will never "work" a day of your life because you will be doing what you like doing.  Of course anything worth getting is  never easy.


Why did I decide to become a professor?   I am (without a trace of inflated pride and with absolute honesty) an excellent teacher.  Former colleagues and administrators have described my teaching as "innovative" "imaginative" "charismatic".    I really like working with students on achieving their life goals.   I think college professors have the most important job of helping develope the leaders of tomorrow in any community.  Many universities have lost their base mission of teaching and develping the next generation and sometimes you will hear things like "It does not matter if we weed out large crops of students.   There are always more students that will come in to replace the weeded out students."    I like teaching at a university which is very student centric.     


I grew up in Columbia, South Carolina.   My parents still live in Columbia in the same house that they have been living in for more than 30 years.   My father, who has a doctorate in Physics retired from teaching at the college level some years ago.   My mother does have a degree in Elementary Education but never taught and worked at a bank before marrying my father.   My mother has always been a very supportive stay at home mom.   My parents are in excellent health and have always been very supportive of my career.


Do I have any children?   I do not have children.   Because I am a woman, studies have shown that students expect more sympathy from me than from men in the same position.  I am not pregnant and I am not running home to nurse a sick child and I have not had first hand experience with any of that.  However  I do have a lot of empathy so I do empathize and if you explain whatever is bothering you, I will try my best to understand.   I do however have to apply the same rules to everyone across the board because we do not want to go down the slippery slope of accepting excuses for missing big things like exams without documentation.

Dr. Hahn's Research Group Spring '09 while at Delaware State U. as an Assistant Professor

(DSU ~3,500 students, 85% African American, Chemistry Department Ph.D. program)

Here are the members of Dr. Hahn's research group during Spring semester '09 from left:   Jose Portela-Berrios (sophomore, Biology pre med), Napreet Tung (junior, Biology, pre-pharmacy), Alex Bishoff (sophomore, Criminal Justice, Army ROTC), Dr. Hahn (assistant professor, Chemistry), Stephanie Blackman (junior, Biology, Army ROTC, Iraq war veteran), Candice Holland (freshman, Sports Science, Army ROTC) All students are being supported by a research grant for an INBRE startup research project on "An Investigation of the Photodimerization of Thymine Implications for Skin Cancer"  to Dr. Hahn, only principal investigator.  

Napreet was actually photo-shopped into the picture because he joined the research group about a week after the others and I could find almost no time when everyone was in the lab at the same time.   (His picture was actually from the pictures which I take at the beginning of the semester in the Organic lecture class.   If you look carefully, you can tell that the background around his head and parts of his clothes are drawn in by hand.)

Dr. Hahn's Research Group Winter Break '08 at DSU as an Assistant Professor

Here are the members of Dr. Hahn's research group during winter break '08.    From left:   Timothy Hokett, Logan Mears, Christen Dillard and Dr. Hahn.  All students were supported by the INBRE startup grant. (winter break was from 12/10W to 12/23T)






Dr. Hahn's Research Group Fall '08 at DSU as Assistant Professor

Here are the members of Dr. Hahn's research group and Dr. Hahn's Organic TA.   from left:   Samantha Koonce, Samantha Noviscky, Tayyaba Toseef, Dr. Juliet Hahn, Christen Dillard, Logan Mears.   Sam K. and Sam N. are supported by NSF HBCU-UP funding, Tayyaba and Logan are supported by Dr. Hahn's principal investigator account and Christen Dillard is the Organic Chemistry Teaching Assistant and is supported through the Division of Academic Enrichment.   The people in my research group are working on (a) the "skin cancer" project (b) the "cocain stereoselective synthesis" project and (c) the "carbon nanotube electrical conductivity"  project.   The virtual blackjack dealer is at Dover Downs across the street from DSU and was on our way back from the "all you can eat" where we held our group meeting.  We weren't really playing blackjack - because we are scientists - we don't gamble.   We are such nerds as to be uber cool.  We just thought the virtual blackjack dealer was interesting.  

It was a very rainy day and we had to walk over to the parking lot almost halfway across campus to the student's cars to drive across the street to Dover Downs.     [My car is always in parking lot 12 in front of the Chemistry Building whenever I am on campus (in fact if my car is not on campus,  you can definitively assume that I am not on campus) but because my car is a 15 year old red Honda Civic Del Sol (named CHEMST) which only seats the driver and 1 other person, we couldn't take my car.]   I  have 4 hot pink umbrellas. I lent one hot pink umbrella to Sam Koonce and lent the other pink umbrella to Tayyaba and carried one myself.    Tayyaba liked my hot pink umbrella so much that she borrowed it to go home and kept borrowing it every time it rained for a few weeks.    My umbrellas apparently went to more interesting places than I have ever gone.   Here is my collection of  my 4 hot pink umbrellas.    Aren't they adorable and don't they look like 4 identical quadruplets even though they are each completely different individuals in its own way?    I would even venture to say that if I saw one of the pink umbrellas without the others, I would swear that I was seeing the one noted pink umbrella belonging to Dr. Hahn.

What I did during Summer 07 at DSU as Assistant Professor:

I worked with undergraduate researchers Ruth Wamwati and Nicole Morris.   Both were supported full time by the NSF through HBCU-UP.   Both were excellent students in my Organic Chemistry class.   Ruth Wamwati consistently had the highest or second highest grade on every exam in the Orgo lecture.   


We worked on developing stereoselective synthesis methodology for cocaine derivatives.    This work has applications in synthesis of pharmaceuticals which can be used to perhaps solve cocaine addiction.   These molecules have potential other neurobiological effects such as analgesics or seizure medications.  For additional information about what earth shattering results the dynamic duo accomplished during the summer, please come see the posters from the student's results on the 3rd floor of  Science Center South.


DSU's brand new 400 MHz NMR (in SCS 107) at DSU as Assistant Professor:    Dr. Hahn prepares to take a sample out of the NMR.  

Dr. Hahn tunes the NMR.   (otherwise known in NMRese as "praying to the NMR gods")

Both Ruth and Nicole got to spend lots of time on our brand new (nearly ~$300,000.00 NSF funded) 400 MHz FT NMR.   We used this nifty piece of equipment  to do advanced techniques such as a number of 2D experiments to fully identify the product of our reactions.

What I did during my spring break:   I presented a talk at the National ACS Meeting in San Diego  March 2005.   "Stereoselectivity in the [2+2] Photodimerizaton of Orotic Acid" by Juliet Hahn*, Brandi Greene, Karen Brawner, Madhvi Patel.    Because I was so busy before the meeting with all those exams that I had to make up, here I am at the airport preparing for the talk.   Here I am at the hotel preparing for my talk and here I am giving my talk.   Otherwise titled "How to take photos by using the auto mode of the camara or how to convince strangers to take your photos?"  I also submitted a paper recently to the National ACS Meeting to be held in August 2005 titled "Synthesis of Derivatives of Orotic Acid" by Juliet  Hahn*, Rachael Butcher, Heather McPherson, Valerie Campbell, Donna Fires.
Dr Hahn's Research Group (Spring 05 semester):

Rachael Butcher and Donna Fires actively did research during the Spring 05 semester.   They were both supported by the FRP research grant.   Also Rachael, Heather and Karen received part of their research support from the NASA/EPSCOR project research grant by a redistribution of the funds in the NASA/EPSCOR research grant (retroactively).   All students worked on the sunlight induced cancer research proposal.

Heather McPherson, Rachael Butcher, Dr. Hahn and Valerie Campbell

Here are the members of Dr. Hahn's research group working hard during the Winter Break.   All three students were supported by Dr. Hahn's FRP research grant and all three worked on Dr. Hahn's "Sunlight Induced Cancer Project".   We worked our fingers to the bone during the break but it was fun.   Here we are just before working up 6 reactions in one day.  We would have worked more except for the snow /freezing rain days.   We all  know how much fun it is doing organic reactions.

4 reactions to be worked up

2 more reactions to be worked up
Dr. Hahn's Research Group: (Fall Break '04)(from left)

Rachael Butcher, Madhvi Patel, Heather McPherson and Dr. Hahn

Rachael, Madhvi and Heather are undergraduate students (all three are excellent students) who worked in Dr. Hahn's research lab during the Fall break.   (Madhvi has been working on the same project all semester supported by the FRP.)   Rachael, Madhvi and Heather all worked on the photodimerization of thymine project.    All three were supported by the FRP research grant.    (Rachael is also an Organic Chem. lab teaching assistant this semester.)   The FRP is actually a research grant  for the "Tropanone (cocaine derivative)" project but the "Tropanone project"  is technically a little more challenging project than the thymine project so everyone is starting out on the easier thymine project to develop technique needed for the tropanone project.   (Both the "Thymine Photodimerization" project and the "Tropanone" project are non-collaborative research projects and the FRP and the NASA/EPSCOR grants were both awarded to Dr. Hahn.)

Dr. Hahn's Research Group: (Summer '04) (from left)

Karen Brawner, Brandi Greene and Dr. Hahn   

Karen and Brandi are undergraduate students who were the best students in Dr. Hahn's Organic Chemistry I class last year.   Karen was supported by the FRP research grant and Brandi was supported by the NASA/EPSCOR research grant this summer.  Both Karen and Brandi worked on the synthesis of a derivative of thymine (one of the components of DNA) to simulate the photodimerization of thymine in DNA which is of interest for understanding sunlight induced cancer.  Both students received credit for doing the research during the summer by registering during the Fall '04 semester for research.    Brandi worked full time while being supported on  research and because of ASU regulations was not able to sign up for research while actually doing the work and Karen started working in Dr. Hahn's lab after the registration deadline for the semester.    Karen has been accepted to the Southern College of Optometry.     Best wishes on her future success as an optometrist.
