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.

Alexa Strauss ‘19, a Chemistry and MB&B double 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)

The 3rd annual Big Drop was held on May 9 outside the Exley Science Center to mark the last day of classes for the Spring semester. A series of smashable items—including water balloons, bouncy balls, watermelon, apples, pineapple, discarded computer equipment, plastic, and Oobleck—were dropped from the building’s rooftop. The Free Radicals also contributed a variety of explosions including the burning of an Orgo Lab report in liquid oxygen.
Chemistry majors Christine Little, Emily Kessler, and Cody Hecht, along with three MB&B majors, attended the annual Experimental Biology (EB) conference in San Diego in mid-April. All three were invited as members of the American Society of Biochemistry and Molecular Biology (ASBMB), a participating society of EB. At the meeting, Christine, Emily, and Cody each competed in an undergraduate poster competition (in which Christine was awarded an honorable mention for an exceptional poster!) and presented their posters in sessions according to their area of research.
Christine’s project in Ishita Mukerji’s lab focuses on characterizing the binding interactions of yeast histone H1 to DNA four-way junctions. Cody’s research in Erika Taylor’s lab investigates the protein dynamics of Heptosyltransferase I as part of ongoing inhibitor design efforts. Emily’s work in Manju Hingorani’s lab concentrates on the link between mutations in DNA mismatch repair protein MutS and Lynch Syndrome.
Five senior chemistry majors have been elected to the Gamma Chapter of Phi Beta Kappa. They will be honored at an induction ceremony on Saturday, May 26, 2018 at 4:00 p.m. in the Chapel. The honorees are:
Kenneth (Cody) Hecht
They join Maya Marshall and Aaron Stone, who were elected in the fall semester. This has been a banner year for chemistry students and we proudly extend our congratulations to all.
Members of the Personick research group (left to right: David Solti ’18, Melissa King (grad), Prof. Personick, and Danny Robertson ’18) attended the American Chemical Society Spring National Meeting in New Orleans, LA from March 18-22, 2018. Danny gave a talk on Sunday on “(Ag)Au concave cubes as experimental models of computationally predicted active sites for the oxygen-assisted coupling of alcohols.” Melissa presented on Wednesday about her work on “Coupling competitive surface interactions: a synthetic route to enhanced grain boundaries at the exterior of multiply twinned palladium nanoparticles.” On Thursday, Prof. Personick presented the group’s recently published research regarding “Approaches for bridging dissimilar reduction kinetics in the synthesis of bimetallic nanomaterials.” All of the talks were well received by their respective audiences.
In addition to presenting their research, the Wesleyan contingent also recruited prospective graduate students for the Wesleyan PhD program at the graduate school recruiting fair, and Melissa was invited to participate in a panel on “Graduate School: The In’s and Out’s of Getting In” which was very highly attended. Prof. Personick caught up with Wesleyan alum Prof. John Keith (Univ. of Pittsburgh) over breakfast, and everyone spent time sampling the local cuisine.
Daniel Robertson, a senior chemistry major, has been awarded a travel grant from the Division of Inorganic Chemistry of the American Chemical Society (ACS). The grant will help defray the costs for him to attend the 255th National Meeting of the ACS, where he will be presenting on his recent research in Prof. Michelle Personick’s lab. His talk is titled “(Ag)Au concave cubes as experimental models of computationally predicted active sites for the oxygen-assisted coupling of alcohols”. The selection criterion for this competitive award is the scientific merit of the work being presented. The meeting will be in New Orleans during the second week of the Wesleyan spring break. If you are attending the meeting, Danny’s talk is scheduled for Sunday, March 18 at 8:50 a.m. in room 212 of the Convention Center. He and Prof. Personick would be delighted to have you there.
