My research focuses on Machine Learning, Artificial Intelligence, Compilers, Networking, High-Performance Computing, Distributed Computing, Optimization techniques and Graph algorithms.

More recently I have been involved in applying by computer science background in understanding the fundamental problems and techniques in modeling the brain and in the design of a platform for neural computation.
