Research Interests

I am a research scientist in the neuroscience group. My current research interests are in theoretical and computational neuroscience and machine learning.

Before joining the Simons Foundation, I was a postdoctoral associate at the Janelia Research Campus of the Howard Hughes Medical Institute. Previously, I was a Swartz fellow at Harvard University. I hold a doctorate in physics from Brown University.

My Google Scholar profile can be found here.

My ResearchGate profile can be found here.
