The Tomchik Lab

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. 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.

Seth Tomchik

Roy J. Carver Professor of Neuroscience

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.

Valentina Botero

Postdoctoral Research Associate

Dr. Botero earned her bachelor’s degree in neuroscience and behavior from Mount Holyoke College and her Ph.D. in the Scripps' Skaggs Graduate School of Chemical and Biological Sciences. Her postdoctoral research in the Tomchik lab is focused on studying the effects of neurofibromin loss of function on metabolic homeostasis, including modulating metabolic rate, feeding, and energy stores.
