My laboratory is interested in neurobiological mechanisms of learning and
memory from the molecular to the behavioral levels, with a major focus on
rapid forms of learning. The brain structures on which we have concentrated
include the hippocampus, amygdala, and perirhinal cortex. Collectively, they
are implicated in aspects of declarative and emotional learning as well as
aging-related forms of neuropathology and accompanying behavioral or mental
changes. The experimental knowledge we gain about synapses, circuits and
systems is incorporated into computational models for theoretical studies.
