The Seth Tomchik Laboratory
Neuroscience of Learning, Memory, and Genetic Disorders
Our research focuses intensively on uncovering the mechanisms of neuronal plasticity and its alterations in genetic disorders such as neurofibromatosis type 1. We strive to develop and maintain an open, collaborative lab environment, continually increasing the creativity and depth of our science, fostering the development and advancement of our lab members. We value diversity and see it as a contribution to our success. Our lab is located at the University of Iowa, Carver College of Medicine, in the Department of Neuroscience and Pharmacology and the Iowa Neuroscience Institute. Dr. Tomchik has additional appointments in the Stead Family Department of Pediatrics and the FOE Diabetes Research Center. If you are interested in joining the team, check out our open positions.

The Team
Seth Tomchik
Roy J. Carver Professor of Neuroscience and Pharmacology
Associate Director for Education, Iowa Neuroscience Institute
Dept of Neuroscience and Pharmacology
Stead Family Department of Pediatrics
FOE Diabetes Research Center
Hawk-IDDRC
Dr. Tomchik received his bachelor’s degree in psychology and Ph.D. in biology from the University of Miami. His postdoctoral research at the Baylor College of Medicine and The Scripps Research Institute focused on the neuroscience of learning and memory. He started his lab at Scripps Florida in 2012 and moved to the University of Iowa in 2022. His current research focuses on how learning and neuronal plasticity alter the flow of information in the brain, and how these normal processes are disrupted in disease states.
Aaron Stahl
Assistant Research Scientist
Dr. Stahl received a bachelor’s/master’s degree in biology from the University of Northern Iowa and a Ph.D. in biology from the University of Cincinnati. His postdoctoral research focuses on the function of neuronal circuits underlying learning and memory.
Valentina Botero
Postdoctoral Research Associate
Dr. Botero earned her bachelor’s degree in neuroscience and behavior from Mount Holyoke College and received her Ph.D. in the Skaggs Graduate School of Chemical and Biological Sciences at The Scripps Research Institute. Her postdoctoral research in the Tomchik lab is focused on studying the effects of neurofibromin loss of function on metabolic homeostasis, including feeding and basal metabolic rate.
