Interests

I am interested in the computations that permit intelligent agents to perform inference, planning, and control.  This includes specifically how the brain builds representations, plans, and produces actions.  I am also interested in leveraging statistical tools to enable more rigorous experimental investigation and analysis of data related to how the brain implements these computations.  Towards this end, I enjoy working on normative solutions to neuroscience problems and collaborating on increasingly naturalistic neuroscience experiments that investigate ethologically relevant behaviors and capacities.

My research thus far has related to methods for analyzing neuroscience-related data, brain-computer interfacing, and other topics.  Feel free to check out my google scholar profile.
