Cynthia Downs, Assistant Professor of Biology

B.S., State University of New York College of Environmental Science and Forestry; Ph. D., University of Nevada
Full Profile
Areas of expertise: ecoimmunology, vertebrate physiology and evolutionary physiology

Cynthia Downs is an ecological physiologist who investigates how the diverse physiological traits expressed by animals alter an animal’s interaction with its environment and mediates the animal’s ecology and evolutionary trajectories. Her research focuses on the organismal level, but she integrates across levels of biological organization to ask questions about how animals work. Downs' research program seeks to understand several things: mechanisms that mediate physiological traits and trade-offs; how physiological traits determine life histories, and how environmental conditions affect physiological phenotypes. She received a doctorate from the University of Nevada Reno, and completed postdoctoral appointments at Ben-Gurion University of the Negev and the University of Nevada Reno.

David Gapp, the Silas D. Childs Professor of Biology

B.S. and A.M., College of William and Mary; Ph.D., Boston University
Full Profile
Areas of expertise: endocrinology of reptiles, with a focus on the action and evolution of gastrointestinal and pancreatic hormones

David Gapp concentrates on comparative endocrinology of reptiles, with a focus on the action and evolution of gastrointestinal and pancreatic hormones. His recent identification of "diabetes" in a local population of snapping turtles may provide an interesting model to pursue the study of this serious metabolic disease that affects a significant portion of the American population. Gapp has written and reviewed manuscripts for notable journals including The Journal of Comparative Endocrinology and Physiological Zoology, and he has received research grants from the National Institutes of Health and the National Science Foundation.

Herman Lehman, Professor of Biology

B.S., University of West Florida; Ph.D., Florida State University
Full Profile
Areas of expertise: cellular neurobiology and neuroethology; measurement and detection of neurotransmitters; isolation and identification of novel chemical messengers; cellular metabolism in the nervous system

Herm Lehman's research is focused on the development and function of neurotransmitters. Neurotransmitters are molecules released by neurons and mediate communication throughout the nervous system; thus, the proper expression and maintenance of neurotransmitter levels is a critical, yet largely unknown, aspect of the metabolism of the neuron.

Alexandra List, Assistant Professor of Psychology

B.A., University of California, Berkeley; Ph.D., University of California, Berkeley
Full Profile
Areas of expertise: cognitive neuroscience of perception and attention, experimental psychology, cognitive psychology and human neuropsychology

Alexandra List received a National Institutes of Health National Research Service Award for both her doctoral and post-doctoral research. List's research has focused on understanding how we perceive and attend to visual, auditory and haptic information in our environment. She uses a variety of human cognitive neuroscience techniques. Her work has been published in various journals, including Cognition, Brain, the Journal of Vision, Neuropsychologia and the Journal of Experimental Psychology: Human Perception and Performance. She earned her bachelor's degree in cognitive science and doctorate in psychology at the University of California, Berkeley.

Ravivarman Thiruchselvam, Assistant Professor of Psychology

Ph.D., Stanford University
Full Profile
Areas of expertise: emotion, emotion regulation, affective psychopathology, EEG/ERP Method

Ravi Thiruchselvam's research uses neuroscience methods (EEG/ERP) to understand emotion and emotion regulation in healthy and clinical populations. At Stanford, he was awarded the Psychology Department’s Hastorf Prize for Excellence in Teaching. Thiruchselvam's research has been published in top journals, including Psychological Science. He grew up in Toronto and completed his doctorate in psychology at Stanford University. He joins Hamilton College as an assistant professor of psychology.
