Research interests:

The primary focus of my research program is to determine the contributions of different brain structures to

learning, memory, and emotion. Specific aims are to: 1) understand the neural circuits involved in acquiring,

storing, and retrieving memory; 2) delineate the mechanisms involved in long-term consolidation and

temporally graded retrograde amnesia; and 3) determine how deficits in emotion may undermine mnemonic

function. Related research projects normally involve assessing whether surgical lesions and pharmacological

manipulations in rats cause anterograde and/or retrograde amnesia as well as changes in fear and anxiety

in several types of behavioural paradigms.

A second focus of my research program is to examine the means to reverse or attenuate cognitive deficits,

such as memory loss, by promoting regeneration of damaged brain circuitry. Projects examine the effects of

promoting neurogenesis with different treatments (e.g., growth factor, enriched environment) on recovery of

mnemonic function from a cellular to a behavioural level.
