Ila Fiete

Ila Fiete is an associate professor in the Department of Neuroscience at the University of Texas at Austin. Fiete’s interests are focused on using computational and theoretical tools to better understand the dynamical mechanisms and coding strategies in the brain.[1]

Education

The earliest record we have of Ila Fiete’s education was in 2004 as she graduated from Harvard University in order to join the Department of Physics. For two years after that, she was a Postdoctoral fellow at the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara. From 2006-2008, Fiete was a Broad Fellow in Brain Circuitry at California Institute of Technology.

Career

After obtaining her Ph.D. at Harvard in 2004, Fiete participated in research in theoretical and computational neuroscience in the Department of Brain and Cognitive Sciences at the Massachusetts Institute of Technology under the guidance of Sebastian Seung. Also, after her fellowship at the California Institute of Technology in 2008, Fiete began to work as an Associate Professor in the Department of Neuroscience at the University of Texas at Austin.[1]

Accomplishments

Fiete has been recognized for a wide variety of awards and distinguishments including as an, Alfred P. Sloan Foundation Fellow, Searle Scholar, Office of Naval Research Young Investigator, and as a McKnight Scholar. As of now, she is a Howard Hughes Faculty Scholar and a fellow in the Center of Learning and Memory at the University of Texas at Austin.
