Bio
A formal bio is here.

Research
My research focuses on computer vision, often making heavy use of machine learning techniques and often using the human visual system as inspiration. For example, temporal processing is a key component of human perception, but is still relatively unexploited in current visual recognition systems. Machine learning from big (visual) data allows systems to learn subtle statistical regularities of the visual world. But humans have the ability to learn from very few examples. Here's a old talk (from 2015) that discusses some thoughts on these issues.

I currently direct the Center for Autonomous Vehicle Research.
