My research focuses on the computational foundations of intelligent behavior. We develop theories and systems pertaining to intelligent behavior using a unified methodology – at the heart of which is the idea that learning has a central role in intelligence. We attempt to understand the role of learning in supporting intelligent inference and use this understanding to develop systems that learn...

Palynological analysis of Sphaeropteris gardneri (Cyatheaceae, Pteridophyta).
