My research interests are in the fields
of behavioural neuroscience and developmental
neuroendocrinology. I investigate how environmental
experiences (e.g., exposure to social stressors,
hormones, malnutrition) either prenatally,
neonatally, or during adolescence, alter
cognitive and emotional behaviour in adulthood
in laboratory rats. I also investigate the
physiological and neurochemical underpinnings
of the effects of early life experiences,
as well as how the early experiences alter
the animal's vulnerability to addictive
drugs. Related research areas of mine are
the investigation sex differences in the
effects of early experiences, and how the
hypothalamic-pituitary-adrenal stress response
is influenced by the actions of sex hormones
in the brain. A third research interest
is how hormones (testosterone, cortisol, estradiol) influence neuropsychological function in people.
