Research


I study the computational mechanisms that neurons use to encode sensory information, focusing mostly on how ganglion cells in the retina encode visual information. More generally, I am interested in bringing together tools from statistics, machine learning, and high-dimensional data analysis to bear on problems in systems neuroscience. I am co-advised by Surya Ganguli and Steve Baccus.
