Congratulations to Nawshin on receiving the CUNY Jonas E. Salk Award

May 31, 2025

Nawshin’s excellent work on the cognitive and cellular effects of acute vs chronic demyelination was recognized with the Jonas E. Salk Award! Thank you to Carmen Melendez-Vasquez, our partner in crime and resident myelin and multiple sclerosis expert, for her insight and co-mentorship. Nawshin’s work delves into how progressive demyelination affects anxiety, memory and neural activity in relevant brain regions.
