Sweet Home Colorado!
The poster presentation went really well. I never went longer than about 60 seconds without explaining my poster to someone. I got a lot of really good feedback and being able to give an overview of my research was really rewarding! I'm looking forward to presenting at Western. Some new discoveries have been made since my poster was printed, so I'll be glad to make those updates and have a full overview of my summer.
Thank you again to everyone that has taken the time to read my blog. I have really enjoyed the opportunity to recount all the fun I had in Tennessee!

Kentucky has lots of caves and lots of corn!
Hopefully that summarizes the summer a bit. We go on a lot of field trips! We have had to buckle down lately though. Our poster presentation is next Tuesday. My poster is printed and in my possession. All I have left to do now is prepare for the presentation. It's been an amazing summer! I can't believe it's almost over. Thanks for keeping interest in all the happenings here at Vanderbilt. I'll be sure to write a post about the poster session. I hope everyone is having a great summer!!

HACKED!
The weekend before July fourth weekend, my mom and my grandma drove down to Tennessee to visit. My mom drove over 20 hours to get here, my grandma was in the car for 10 of them, they accidentally woke up at 1:30 in the morning to get on the road, and once they got here they slept on a queen size blow up mattress in the living room. They are troopers!! I'm so thankful that they came. It was so nice to see family and I had a really great time showing them the sites. I showed them my favorite parts of campus, we went to the Parthenon and the Whiskey Bent Saloon on Saturday, and on the last day we drove to Chattanooga to see the Chattanooga Choo Choo and the highly acclaimed Chattanooga Aquarium. We certainly packed a lot into a weekend, but it was worth it. I was sad to see them go, but they were off to see more of the sites in Arkansas and Missouri before they made the trek home to Colorado.
July fourth weekend was fairly laid back. I was really excited to go see a boat parade, but apparently it was cancelled. We drove around the lake for about 20 minutes asking everyone we saw where the boat parade was and they either looked at us like we were crazy or told us that it was not happening this year. I figured that a 4th of July parade would be an annual thing, but maybe they skip a year. Either way, we went to the lake for the day, walked around by the water, and ate some watermelon. The highlight of the weekend was the fireworks. They put on the most amazing fireworks show here in Nashville and everyone comes to see it! Finding a place to sit and watch was quite the challenge, but it was worth our efforts. The fireworks cover the whole riverbank and they last for about fifteen minutes. Gorgeous is the only word I can think of to describe it.
That brings us up to this weekend. On the 10th, our program went to Kentucky and took a tour of Mammoth Cave. We chose to go on the lantern guided tour that was 3 miles long. Fortunately, there is a tour guide that goes through the cave with you and points out areas of interest. If it weren't for him, I'm convinced I wouldn't have seen 90% of the attractions he showed us. I think that my favorite was the illusion of a starry night. Years of people taking tours and using gas lanterns has turned some of the rock black. During one section of the tour they had us sit and they hid our lanterns away. At first the roof of the cave looked completely black, but with the lanterns hidden away we could see small specks of limestone shining through creating the illusion of the night sky. Our tour guide told us that in the past tour guides had told cave visitors that their tour had concluded and the mouth of the cave was revealing the true night sky. The cave has been a tourist spot for quite some time so we were able to hear about the history of the cave and see the many sites that have taken hundreds of years to discover.
After the cave we went to our program coordinator's farm and had a cook out. We cooked hot dogs and s'mores over a bonfire, we trekked through the corn fields, rode on four wheelers down to the spring, and we went frog giggin'. That's right folks, I went hunting for frogs. Don't worry, all the small amphibians are safe with me around. I don't have very good aim with the gig. It was a great way to spend a Saturday!
Well I guess that's everything! Just kidding! Everyone of my professor's out there is probably thinking that my summer sounds like a whole lot of play and not a whole lot of work. I'm glad to report that I have been making progress in the lab. All the computational optimizations are complete and I have already begun making comparisons between the experimental and computational results. I was entrusted with some new software today. My mentor has never used it before so he asked me to work out the kinks and report back to him. Once I have the program all figured out, the calculations it does should prove to be very useful. The poster session is about three weeks from today. Recently, we were asked to turn in a title for our project; the title of my work is Conformational analysis of hibiscus acid disodium salt and hibiscus acid dimethyl ester using chiroptical spectroscopic methods. Well at least that is the title for now. I think that it's a bit of a mouthful, but hopefully with some revision I'll come up with something more appealing.
One of the upsides of the program is the constant introduction to various parts of science. Every Friday we have a lunch seminar led by a different Vanderbilt professor. We learn a bit about the projects labs are working on, the opportunities available for a Vanderbilt graduate student, and other opportunities available in the field of science. A couple weeks ago the program coordinated a drug discovery day and we were able to talk to a group of Ph. D's that have experience in both the pharmaceutical industry and the pharmaceutical research at Vanderbilt. I really enjoyed listening to their experiences and learning more about the opportunities available to me.
To wrap up this long list of activities, I wanted to tell a bit about our field trip to Oak Ridge National Laboratories (ORNL). ORNL is most famous for their contributions to the atomic bomb, but there is a lot of new and exciting research going on there now. They have the fastest super computer in the world and they are currently building one that will be even faster. We were able to tour their particle accelerator and they're pristine clean room. The day was filled with information about exciting new science projects!
Well, there you have it folks. Three weeks summed up in one lengthy blog. Thank you for staying tuned!

Making Headway!
My time spent in the lab was filled with new experiences. Last Monday, I worked in another lab and assisted a graduate student in completing an esterification reaction. For past blog followers, this was the esterification of hibiscus acid that I mentioned before. The synthesis was exciting and fairly straight forward. My tortoise shell goggles made their feature debut along with a brand new lab coat and some fancy blue nitrile gloves. After looking at nuclear magnetic resonance readings we decided we had made the product; unfortunately, we also discovered an impurity. The graduate student told me he would work on some purification ideas and get back to me. He found a way to get rid of the impurity, but he accidentally undid our reaction in the process. Luckily, we had plenty of starting material, and Ed, the graduate student I worked with, offered to redo the reaction over the weekend. Although I would have enjoyed delving into some more organic chemistry, I had already made plans for the weekend.
The time had come to delve even deeper into the south! My roommate Austin is from a suburb of Birmingham, Alabama so she was kind enough to take us with her to visit her family. Austin's family owned a boat a little over halfway between Nashville and her home. We met Austin's dad at the lake and he was kind enough to take us out for the day. It was a blast! We went tubing, laid out on the dock, and felt the wind whip through our hair as we cruised around the lake. The lake itself was gorgeous. There were tons of homes with eye catching architecture planted all around the lake and deep green trees covered the shoreline. We were so fortunate that the weather was nice while we were there. The whole way driving to the lake, Austin had to battle against a torrential rain storm, but about fifteen minutes out from the lake everything stopped. Not only was it not raining when we arrived, it didn't rain the whole time we were there! Are we lucky, or what? To top it all off, we spent the night at Austin's home and her mother made us a gourmet dinner with peach cobbler for dessert. It was like a little piece of heaven! I cannot thank Austin's family enough for all their hospitality.
Sadly, the weekend did have to come to an end, but so far this week in lab has been very productive. I finished the ORD and ECD measurements of one of the compounds and I will begin VCD measurements tomorrow!
I would like to wish a Happy Father's Day to all the dad's out there! I hope everyone is enjoying the weather back home. I hear the the sun has been shining in Colorado. I look forward to sharing with you all again soon!

Getting My Hands Dirty

Mission Completed!
Although uncovering the perfect pair of boots was exciting, I was part of far more interesting activities this week. Today was the final day of the three day chirality workshop hosted by my mentor, Dr. Prasad Polavarapu. The focus of the conference was discussing the different instruments used to determine the absolute conformation of molecules: Optical Rotary Dispersion, Electronic Circular Dichroism, Vibrational Circular Dichroism, and Raman Optical Activity. There was also a presentation on the Chiral HPLC and Supercritical Fluid Chromatography instruments used at Vanderbilt for isolation of enantiomers. Given my background in HPLC, I was most intrigued by the HPLC demonstration. I never realized how much could be accomplished with an HPLC and I was given advice about how to better my own results. (Dale, I thought you would be glad to hear that the expert I spoke with here believes that the water pump on the instrument is most likely faulty. I will have to run some tests when I get home because I didn't get the chance before I left. Hopefully, I will be able to eliminate the drift in my chromatograms).
Due to my lack of knowledge about circular dichroism I found some of the lecture material a little difficult, but the instrument demonstrations were really impressive. Many people from industry attended the conference and told us a bit about how far their instruments had come. The Vibrational Circular Dichroism (VCD) instrument is fairly new to the market. The instrument we have in our lab was the second instrument ever made and it was installed in June of 1998. In 2005 the instrument was updated with the addition of a second photoelastic modulator. The instrument is now considered a Dual PEM VCD. PEM is simply an acronym for photoelastic modulator. Having two PEM's rather than one reduces the number of artifacts and the background noise. I feel very fortunate to have the opportunity to work with such advanced instruments and I am sure I am going to learn a lot.
I am also looking forward to learning about computational methods. An important facet of the conference was discussing the quantum mechanical calculations that are being used to predict molecule conformations. All spectra from the instruments measured are compared to computationally produced results in order to identify the absolute configuration. If the experimental and the computational results correspond well, a correct configuration has likely been uncovered. It is important to mention that one should never use just one method for measuring chirality, but instead use multiple instruments to increase the possibility for correct identification. This summer I will have the opportunity to be trained on two computer programs called Linux and Gauss View and I will be able to use the super computer on campus for calculations.
I truly feel blessed to be exposed to so many new things. Different comments made at the conference made me realize that Dr. Polavarapu is truly on the cutting edge of chirality studies. He also has connections with people from various industries and countries. Companies like Jasco, Biotools, Amgen, and Hinds Instruments were all represented at the conference and there were attendants from France, India, Poland, and Guatemala, just to name a few. Having Dr. Polavarapu as my mentor means that I will be working with the best! As I learn more about the instruments I will try to tell you all more. Some of the information is difficult to explain without diagrams, but I'll do my best. Maybe I can attach a diagram to my blog. I still haven't figured out all the fancy tricks. Either way, I'll keep you all updated. Thanks for reading!
P.S. Sorry for the lack of pictures. I forgot my camera cord at home, but luckily Lisa has offered to ship it to me! I'll try to post some pictures soon!

Enjoying the sites!
Although the trip was tons of fun, all the splashing and boat flipping left me feeling rather exhausted. When we got back I took a nice long nap and woke up just in time to enjoy the night life of Nashville. A few of the girls and I went down to 2nd Avenue and saw all the sights. There were tons of bars with live music, various street performers, and lots of shops that are named after country icons. One woman we saw was playing spoons. I had always heard of such a talent when I was a child and was banging my spoon on the kitchen table, but I had never seen the act in real life. I can say without a doubt that this woman's spoon antics brought much more musical joy than my attempts as a child.
Even though we enjoyed the sites and getting a better feel for Nashville, we went to 2nd Avenue for a particular purpose: buying cowgirl boots! The CMA music festival is next weekend and a couple of us girls think it would be fun to have a pair of boots to wear. Unfortunately, we did not realize that authentic cowgirl boots cost about $100 dollars and that's only if they are on a really good sale. We have decided to refine our boot search and settle for boot knock offs. We are going to go to a nearby mall this afternoon to see what we can find. I'll be sure to keep you updated on the mission. Oh, and I'll try to let you know about the research some as well. I am going to a three day chirality workshop this week. I am really excited to learn all about the instruments and meet people from various colleges, labs, and industries.
