Research theme: Signal processing, representation, and communication in the neural systems
To understand the brain we should be able to explain what it does, how, and why
(in other words, "what it computes, how it computes, and what it should compute" --
M. Carandini).
To this end, I'm currently working on low-level vision - the early stages of the hierarchical visual system.
