Research Theme


My diverse research interests include nonlinear dynamical systems, recurrent neural networks, reinforcement learning, time-series modeling, computational neurodynamics, neurorobotics, optimization & control. Overall, I am interested in statistical machine learning as a field and in searching for novel theoretical frameworks to build adaptive intelligent systems.

Previously I was leading an IBM Research-Tokyo Far Reaching Research project on closed-loop experience building embodied robots learning framework (CLEBER). CLEBER is not only applicable to robots, but is a framework for online sequential decision making in an application independent manner.
