About I'm interested in comparative cognition and behavior. This includes questions like: How do animals represent their world? How are these representations built? and How do these representations subserve information processes?
To answer these questions, my research uses Pavlovian and instrumental conditioning procedures to study how laboratory rats and pigeons (and occasionally humans) solve problems involving cause-effect relations, how they encode and use spatial and causal knowledge in decision making, and how they construct more complex representations from simpler ones.
