Bio

My research interests include the neurobiology of stress and addiction and how these can interact to affect the vulnerability of an individual to drug addiction. I am particularly interested in developmental aspects of stress/drug interactions and currently focus on adolescent models of stress. I am asking how adolescent social deprivation can combine with social cues during drug exposure to impact the effects of drugs such as cocaine and opioids on reward and neurochemistry. Other interests include the neurobiology of mood disorders such as social anxiety, sex differences in stress/drug interactions, and the role of glial cells on addiction and mood disorders. Some of the techniques I use are in vivo microdialysis and high performance liquid chromatography (HPLC) to assess levels of the neurotransmitters dopamine and serotonin in the brain, conditioned place preference to assess drug-seeking behavior, as well as immunohistochemistry to detect changes in protein expression, and in situ hybridization to detect changes in gene expression, within regions of the brain associated with reward and emotion, including the medial prefrontal cortex, nucleus accumbens, and amygdala.
