Science in Society major Stacy Uchendu '17 is participating in Wesleyan's Ronald E. McNair Post Program, which assists students from under-represented groups in preparing for, entering and progressing successfully through post graduate education. Stacy is researching second generation biofuels as a McNair Scholar.

On June 15, Erika Taylor, assistant professor of chemistry, assistant professor of environmental studies, received a grant from the National Institute of Allergy and Infectious Diseases (part of the National Institutes of Health) to support her research on “Inhibition of (the enzyme) HeptosyltransferaseI for the treatment of Gram-negative bacterial infection.” Gram-Negative bacteria include things like E. coli, Salmonella, and V. cholerae (the cause of Cholera) that are common causes of food-bourne illnesses. The grant, worth $492,000 will enable her to engage multiple graduate and undergraduate students in the proposed work through June 2018. Preliminary results for this project were obtained…

Erika Taylor, assistant professor of chemistry, assistant professor of environmental studies, has co-authored a paper published in FEBS Letters, an international journal established for the rapid publication of final short reports in the fields of molecular biosciences. The paper, which is an expansion of her lab’s work on the enzyme Heptosyltransferase I, is titled "Cloning and Characterization of the Escherichia coli Heptosyltransferase III: Exploring Substrate Specificity in Lipopolysaccharide Core Biosynthesis," The paper is co-authored by her former graduate student Jagadesh Mudapaka. FEBS Letters is published by Elsevier on behalf of the Federation of European Biochemical Societies. Taylor also is the co-author of “Improving Alternate Lignin Catabolite Utilization of LigAB…

#THISISWHY Duminda Ranasinghe, a Ph.D. candidate in Chemistry, spoke April 16 in Exley in the fourth event of the Graduate Student Speaker Series. (Photos by Hannah Norman '16.)

Christina Othon and Erika Taylor, along with physics graduate student Nimesh Shukla, Lee Chen ’15, Inha Cho ’15 and Erin Cohn ’15, are the co-authors of a paper titled “Sucralose Destabilization of Protein Structure” published in The Journal of Physical Chemistry Letters, March 2015. Othon is assistant professor of physics and was PI on the paper. Taylor is assistant professor of chemistry, assistant professor of environmental studies. Sucralose is a commonly employed artificial sweetener that behaves very differently than its natural disaccharide counterpart, sucrose, in terms of its interaction with biomolecules. This research suggests that people may need to think about the impact…

#THISISWHY About 30 Wesleyan students and faculty gathered for a Wesleyan Women in Science (WesWIS) Tea Reception Feb. 19 at the Wasch Center. Women in Science is a student group composed of undergraduates, post-docs, staff and faculty dedicated to issues affecting women in science. The group is open to all majors and genders. During the gathering, guest speaker Michelle Francl, professor of chemistry on the Clowes Fund for Science and Public Policy at Bryn Mawr College, spoke to the group about physicist and chemist Marie Curie, the first woman to win a Nobel Prize. Francl handed out copies of her commentary titled…

Brian Northrop, assistant professor of chemistry, is the co-author of several new papers including: “Preparation and Analysis of Cyclodextrin-Based Metal-Organic Frameworks: Laboratory Experiments Adaptable for High School through Advanced Undergraduate Students,” published in Journal of Chemical Education 92, pages 368-372, 2015. Samantha Angle, a Middletown High School student working in Northrop’s lab, co-authored the paper. (See cover at left.) "Rational Synthesis of Bis(hexyloxy)-Tetra(hydroxy)-Triphenylenes and their Derivatives," published in RSC Advances 4, pages 38,281-392 in 2014; "Vibrational Properties of Boroxine Anhydride and Boronate Ester Materials: Model Systems for the Diagnostic Characterization of Covalent Organic Frameworks,” published in Chemistry of Materials 26, pages 3,781-95 in 2014; And “Allyl-Functionalized Dioxynaphthalene[38]Crown-10 Macrocycles: Synthesis, Self-Assembly,…

Stewart Novick, chair and professor of chemistry, is the co-author of several papers published in 2014. They include: "The microwave spectra and structure of the argon-cyclopentanone and neon-cyclopentanone van der Waals complexes," published in the Journal of Physical Chemistry A 118, pages 856-861; "The shape of trifluoromethoxybenzene," published in the Journal of Molecular Spectroscopy 297, pages 32-34; "Fluorination effects on the shapes of complexes of water with ethers: a rotational study of trifluoroanisole-water," published in the Journal of Physical Chemistry, A 118, pages 1,047-51; "Measurement of the J = 1 - 0 pure rotational transition in excited vibrational states of…

Michael Frisch, research professor of in chemistry, is the co-author of many articles published in 2014. They include: “Analytical harmonic vibrational frequencies for the green fluorescent protein computed with ONIOM: Chromophore mode character and its response to environment," published in the Journal of Chemical Theory and Computation, 10, pages 751-766; “Quantum calculations in solution for large to very large molecules: A new linear scaling QM/continuum approach," published in the Journal of Physical Chemical Letters, 5, pages 953-958; “Density of states guided Møller-Plesset perturbation theory,” published in the Journal of Chemical Theory and Computation, 10, pages 1,910-14; “Practical auxiliary basis implementation…

Erika Taylor, assistant professor of chemistry, assistant professor of environmental studies, is the author of a paper "Exploring Allosteric Activation of LigAB from Sphingobium sp. strain SYK-6 through Kinetics, Mutagenesis and Computational Studies," published in Archives of Biochemistry and Biophysics, Vol, 567, pages 35-45, February 2015. Co-authors include graduate students Kevin Barry and Joy Cote; Erin Cohn '15, Abraham Ngu '13 and former graduate student Jason Gerbino. Development of renewable alternatives for petroleum derived fuels and chemicals is of increasing importance because of limits on the amount of fossil fuels that are available on the planet. In an effort to improve the utilization of…

#THISISWHY In this Q&A meet Colin Russell from the Class of 2015. Q: Colin, what are you majoring in? What have been your most instrumental courses so far? A: I am majoring in neuroscience and behavior while also on the pre-medical path. Two of the most instrumental courses in my journey through Wes have been Organic Chemistry and the Organic Chemistry Lab that is paired with the lecture course. The reputation of Organic Chemistry was extremely intimidating prior to taking the course, and I was nervous that I would not like this subject that is the basis for so much of the…
