ResPAC Faculty Representatives

Representing Students in Biology, Chemistry, Environmental Science, Neuroscience, Math and Computer Science


Karen Resendes, Ph.D., ResPAC Chair

Associate Professor, Biology

Dr. Resendes has a Ph.D. in Molecular Biology, Cell Biology and Biochemistry from Brown University. She has done post-doctoral research at the University of California, San Diego and has taught at San Diego State University. Her research focuses on nuclear mRNA and protein transport.



Deanne Buffalari, Ph.D.

Assistant Professor, Psychology Neuroscience

Deanne Buffalari has a Ph.D. in Neuroscience from the University of Pittsburgh. She has done postdoctoral work at the Medical University of South Carolina and the University of Pittsburgh. Her research focuses on the interactions of stress and reward in animal models of addiction.




David Offner, Ph.D.

Assistant Professor, Math and Computer Science

Dr. Offner earned his Ph.D. from Carnegie Mellon University and joined the Mathematics and Computer Science faculty in 2009. His research interests are in combinatorics, graph theory, theoretical computer science, and optimization. Aside from teaching a wide variety of classes, he enjoys mentoring undergraduate researchers and future mathematics educators.



Katherine Robertson, Ph.D.

Associate Professor, Biology

Dr. Robertson has a Ph.D. in Developmental Biology from the University of London. She has done post-doctoral research at Carnegie Mellon University, PA, and has taught at Duquesne University, PA. Her research focuses on learning and memory in social insects.



Jessica Sarver, Ph.D.

Assistant Professor, Chemistry

Dr. Sarver earned her Ph.D. in Chemistry from the University of Pittsburgh. She performed her postdoctoral work at the University of Virginia and taught at Swarthmore College. Her research focuses on investigating the behavior of membrane-associating proteins using biophysical methods.



Ann Throckmorton, Ph.D.

Professor, Biology

Dr. Throckmorton earned a Ph.D from Florida State University. Her research focuses on two areas: behavioral ecology of parasitic insects – how mate selection and host choice affect lifetime fitness – and the antimicrobial properties of natural dyes derived from plants. She is also a member of the Environmental Science Committee which coordinates the environmental science major and Associate Director of the College’s Field Station.
