Once again, the Chemistry Department’s holiday party, organized largely by the graduate students, was held on campus at the Daniel Family Commons at the end of last semester. It is always a highlight of the year and nearly everyone attended. The addition of Wesleyan Chemistry Department Trivia was a huge success (except for the time one answer sheet was incorrectly scored. Never fear, Professor Westmoreland demanded to get his points back!!) And a big thank you goes out to Andrea Lee who organized it for us. Photos from the event are below.
On a recent Saturday, the Free Radicals and chemistry graduate students traveled to Lyman Orchards for an afternoon of apple picking–a first-time adventure for several of the students. After filling their stomachs and bags with apples, Professor Andrea Roberts and the students had a tasty lunch and shopped for delicious cider, cider donuts, and Lyman cheese spread.
According to former Free Radicals officer and MA candidate Giselle Reyes ‘19, “It was nice to be able to spend some time with my fellow radicals outside of Hall-Atwater and fill my belly with tasty apples, donuts, and cider from Lyman Orchards. I discovered my new favorite apple (The Jonamac!) and strengthened friendships along the way.” Truly an unforgettable day for the chemistry majors, students de-stressed and bonded, simply enjoying each other’s company and the beautiful autumn scenery.

One of the special aspects of being a chemistry major is the friendships formed between graduate students and undergraduates during their time at Wesleyan.

The Free Rads hosted a Chemistry Major Interest Lunch on October 12 where they mingled with prospective majors. A representative member from each research lab gave a short presentation about their work. The majors were also able to share their advice on navigating the major while juggling other majors, interests, extracurricular activities, and study abroad. Nearly thirty prospective students participated while enjoying Italian food and informal conversation. Lunch was follwed by lab tours and students were able to peer inside the inner workings of several research labs to see what opportunities await them.

Nearly thirty students arrived to this event to learn about the major or impart advice on the major.

And the Free Radicals live on! The Free Radicals held their first major event on October 6, the annual Tie-Dye Lab Coat event, where the chemistry majors gathered outside of Hall-Atwater on a beautiful Saturday afternoon to dye their own lab coats. The day was organized by the Free Radical officers, Theo Prachyathipsakul, David Cabanero, and Jing Jing Wang with assistance from Professor Andrea Roberts. Around twenty Free Rads enjoyed Thai food and decorated their glamorous new lab coats, courtesy of the Chemistry department. Seniors who already had a lab coat from last year tie-dyed shirts. The group also colorized scarves for Professor Roberts and our administrative staff members, Terry Emmons and Aracely Suto. Check out the pictures from this event below! (submitted by David Cabanero)

Some chemistry majors and their masterpieces
Dr. Tsagan (Tsagana) Ednyasheva successfully defended her PhD thesis, “Novel Asymmetric Syntheses of Rocaglates and Their Analogs through a Cinchona Alkaloid-Catalyzed Interrupted Feist-Bénary-Like Reaction”, on June 20, 2018. Tsagana came to Wesleyan in 2012 after receiving her combined Master’s/Bachelor’s degree in Chemistry from Moscow State University. She had also spent the summer of 2010 working in the Pratt lab, along with her cousin Liudmila (Liuda) Dzhekieva. Tsagana joined Prof. Calter’s lab in the fall of 2012 and worked on a number of projects before settling on a synthesis of the potent anticancer compound, rocaglamide. She developed a rapid synthesis of a new set of analogs of the rocaglamides, taking the Calter group further into medicinal chemistry than it had ever gone. After a long overdue trip to Russia to visit family and friends, Tsagana started her first PhD level job at Exemplify BioPharma, where she joins fellow Calter group alumnus Alexander (Sasha) Korotkov.
The undergraduate summer research fellows presented posters on their accomplishments on July 26. Twenty-six of the presentations were on work done in the Chemistry Department, representing nine different research groups. For more on the event, visit News @ Wesleyan.

The Annual Chemistry Department Summer Picnic was held on June 27. In addition to being a nice break from the usual routine, the annual picnic serves as an effective way of zeroing out the department’s discretionary budget before the end on the fiscal year. Students, staff, and faculty enjoyed the traditional grilled treats. Fireworks (commercial and legal, of course) were a highlight.
A total of thirty-nine degrees in Chemistry were awarded on May 27 at the 186th Commencement. The department proudly congratulates all its new alumni/alumnae.

Stephen Frayne recently defended his Ph.D. dissertation and will be receiving his degree at commencement this May. Steve joined the Department of Chemistry at Wesleyan in 2012 after having received his B.S. in chemistry from Fordham University. At Fordham Steve worked in the laboratory of Dr. Ipsita Banerjee focusing on the rational design of artificial biomaterials. While in the Banerjee group Steve investigated the pH-dependent self-assembly of plant-based acids such as abscisic acid and ellagic acid into templates for the growth of cadmium selenide (CdSe) nanoparticles, with potential applications in bioimaging, cell targeting, and environmental remediation. Upon coming to Wesleyan, Steve joined the lab of Prof. Brian Northrop where he has been conducting experimental and computational research with the aim of streamlining the design and synthesis of organic materials. Much of Steve’s work has focused on the fundamentals of thiol-Michael reactions and, in particular, selective thiol-Michael reactions that enable researchers to synthesize multifunctional polymers and dendrimers more rapidly and efficiently. After graduating Steve will be joining the lab of Prof. Jeffrey Grossman in the Materials Science and Engineering department at the Massachusetts Institute of Technology (MIT) where he will apply his experimental and computational expertise to develop new materials that address important energy related challenges, such as nanoporous membranes for water desalination.
