graduate students

Wesleyan welcomes 162 graduate students to campus this fall, of which 60 are new. Of these: 23 new students are enrolled in the BA/MA programs in biology, chemistry, computer science, molecular biology and biochemistry, neuroscience and behavior, physics, and psychology. 13 new students are enrolled in a two-year MA program in astronomy, earth and environmental sciences, and music.

A paper coauthored by several members of the Robinson Lab is published in the Oct. 3 issue of Behavioural Brain Research, Volume 371. The coauthors include Mike Robinson, assistant professor of psychology; graduate student Charlotte Freeland, Callie Clibanoff '19, Anna Knes '19, John Cote '19, and Trinity Russell '17. The flashing lights and celebratory sounds that dominate slot-machine gambling are believed to promote engagement and motivation to keep playing. However, these cues are often presented in the absence of reward, and previous research suggests that this reward uncertainty, which degrades their predictive value, also increases their incentive value. In their…

Johan (Joop) Varekamp, the Harold T. Stearns Professor of Earth Science, presented three papers during the Commission on Volcanic Lakes (CVL) program held March 18-20 in Taupo, New Zealand. The papers were coauthored by Wesleyan students, graduate students, recent alumni, and faculty. The CVL is a scientific, nonprofit organization of the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI), connecting researchers that seek to understand how volcanic lakes relate to volcanic activity and their hazards. Varekamp, who also is the Smith Curator of Mineralogy and Petrology of the Joe Webb Peoples Museum of Natural History and professor of earth…

Molecular biology and biochemistry graduate student Brandon Case and Professor Manju Hingorani are coauthors of a study published in Nucleic Acids Research in March 2019. The paper, titled “The ATPase mechanism of UvrA2 reveals the distinct roles of proximal and distal ATPase sites in nucleotide excision repair,” reports new findings on how the UvrA2 protein uses its ATPase activity to probe DNA for damage lesions, such as those caused by UV radiation, and initiate nucleotide excision repair (NER). This DNA repair process corrects tens of thousands of lesions introduced daily into the human genome by UV rays and chemical agents. (more…)

Adult neurogenesis, a process whereby new neurons are added to the brain, is thought to be confined in mammals to just a few regions, including the hippocampus, a structure important for learning. Whether this process occurs in the adult human brain is controversial, but in most other mammals that have been studied, adult neurogenesis in the hippocampus appears to be essential for forming memories. Producing new neurons in the adult hippocampus is regulated by the environment, mood, exercise, diet, and disease. In some forms of epilepsy, the production of new cells in the hippocampus, called granule cells, becomes highly abnormal and…

Several Wesleyan students, faculty, and alumni attended the 50th Lunar and Planetary Science Conference (LPSC) March 18-22 in The Woodlands, Texas. Members of the Wesleyan Planetary Sciences Group presented their research on a range of planetary bodies. This annual conference brings together international specialists in petrology, geochemistry, geophysics, geology, and astronomy to present the latest results of research in planetary science. Earth and environmental studies major Emmy Hughes '20 presented a poster titled “Observations of Transverse Aeolian Ridges in Digital Terrain Models" during a session on “Planetary Aeolian Processes.” Earth and environmental science graduate student Reid Perkins MA '19 presented a…

After a star forms, a dusty ring of space debris may begin orbiting around a star. These circumstellar disks are composed of asteroids or collision fragments, cosmic dust grains, and gasses. Astronomy graduate student Jessica Klusmeyer is interested in understanding the molecular composition of the debris disk gas. "It has important implications not only for our knowledge of debris disks but also for planet formation," she said. Klusmeyer joined more than 25 Wesleyan affiliates and shared her research during the 233rd American Astronomical Society Meeting Jan. 6-10 in Seattle, Wash. The American Astronomical Society (AAS) awarded Klusmeyer a Chambliss medal for her poster presentation…

More than 25 Wesleyan affiliates attended the 233rd American Astronomical Society Meeting Jan. 6-10 in Seattle, Wash. All current Wesleyan students who attended presented posters of their research. Campus attendees included: Bill Herbst, the John Monroe Van Vleck Professor of Astronomy and professor, integrative sciences; Roy Kilgard, associate professor of the practice in astronomy and associate professor of the practice, integrative sciences; Michael Henderson '19; Allison Quintana '19; graduate student Jessica Klusmeyer; graduate student Ismael Mireles; and graduate student Anthony Santini ’18. Alumni included Hannah Fritze ’18, Aylin Garcia Soto ’18, Prajwal Niraula MA ’18, Amy Steele MA ’14, Nicole Arulanantham MA…

Two graduate students and three undergraduate students are recipients of Fall 2018 NASA Connecticut Space Grant Consortium (CTSGC) awards. They are among 39 students from 13 CTSGC academic affiliate institutions to be honored. NASA CTSGC is a federally mandated grant, internship, and scholarship program that is funded as a part of NASA Education. There are Space Grant Consortia in all 50 states, plus Washington, D.C., and Puerto Rico. Earth and environmental science graduate student Christina Cauley received an $8,000 Graduate Research Fellowship for her project “Chemistry and Biology of Giant Hydrothermal Mounds in Paulina Lake, Oregon." Her advisor is Joop…

Melissa King, a PhD student in chemistry, and Michelle Personick, assistant professor of chemistry, are the coauthors of a study titled "Iodide-induced differential control of metal ion reduction rates: synthesis of terraced palladium–copper nanoparticles with dilute bimetallic surfaces," published in Journal of Materials Chemistry A, August 2018. In this paper, King and Personick report the use of low concentrations of iodide ions as a means of differentially controlling the reduction rates of a noble metal (palladium) and a non-noble metal (copper). The iodide in this system increases the rate of reduction of palladium ions while concurrently slowing the rate of…
