Neuroinformatics lab

We develop computational models and signal processing tools to decode brain connectivity and function using genomics and imaging. We are particularly interested in constructing a bridge between genetics and behavior through interpretable models that operate on multi-modal neural data at molecular, circuit and whole-brain resolutions.

Erdem Varol (PI)

I’m an assistant professor at the Department of Computer Science & Engineering at Tandon School of Engineering, NYU. I’m also a part of the VIDA center. Previously, I was a postdoc at the Department of Statistics, Zuckerman Institute, Columbia University with Liam Paninski. Before that, I did my Ph.D. at the Department of Electrical & Systems Engineering at the University of Pennsylvania under Christos Davatzikos. Whilst at Penn, I also received an A.M degree in Statistics from the Wharton School. I recently received the NIH/NIMH K99/R00 award in 2022. I’m originally from Ankara, Turkey and grew up in New York City. I have two basset hounds.
