I am currently a Visiting Scholar at the Redwood Center for Theoretical Neuroscience at UC Berkeley.

My general research interest is in how the brain works when viewed as an information processing system, particularly at the level of the neural circuit in vision. I am also interested in human organizations when viewed as systems, and the use of technology to implement intelligent learning behavior.

My current work focuses on biologically-realistic spiking network models of visual pattern detection and "sparse code" formation. Sparse coding is a method for representing information that appears to be used by the brain. Its key characteristic is that very few representation variables (neurons) are active at any given moment.

My latest research project is E-I Net, a neural circuit model and simulation engine written in MATLAB that learns sparse code patterns using an approach inspired by the brain's visual cortex.

Lately I have been answering neuroscience questions on the Q&A website Quora (representative answers) and was selected as a Top Writer for 2013, 2015, and 2016.
