I am an assistant professor in the Department of Neuroscience and a member of the Center for Theoretical Neuroscience and the Zuckerman Institute. Previously, I was a postdoc with Larry Abbott and a grad student with Brent Doiron.
I am looking for talented graduate students and postdocs. If you are interested in joining the group at the Center for Theoretical Neuroscience, please contact me.
