Research interests:

  • Neural Computation
  • Cognitive Robotics
  • Dynamical Systems

Current Research:

My current research focuses on programmable neural networks: neural networks that can be “programmed” like a conventional computer to execute symbolic, cognitive-level tasks, but can then refine that procedural knowledge by learning from examples and experience.  One application of this work is in robotic imitation learning: “programming” robots from a single human demonstration of a task that requires high-level planning and reasoning.  A second application of this work is modeling the neural basis of cognition, and cognitive disorders, in humans.

In other research I am developing new solution methods for fixed point location in recurrent neural networks and other dynamical systems, including gradient flows of optimization objective functions.  This work applies broadly to solving non-linear systems of equations and non-convex optimization.  I have also worked on methods for computational tomography of biological virus particles.

Teaching Interests:

My teaching interests include machine learning and artificial intelligence, especially neural computation and automated planning, as well as dynamical systems, robotics, and human-robot interaction.
