Research Area/s:

Cognition, Brain and Behavior

Research Interests:

  • Neurobiology of drug addiction, including cocaine, amphetamines, alcohol, and nicotine
  • Behavioral and neurobiological consequences of adolescent exposure to nicotine, ethanol, and cocaine
  • Social influences on drug self-administration and relapse, including prosocial interactions and chronic social stress
  • Neurobiology of anxiety and fear related defensive behaviors
  • Examining serotonin (e.g., 5-HT1B, 5-HT2C, 5-HT2A) and corticotropin-releasing factor (CRF1) receptors as novel targets for treating drug addiction and affective disorders
  • Changes in microRNA expression following exposure to chronic social stress and drugs of abuse.
  • Role of stress systems in modulating depressive- and anxiety-like behaviors in rodent transgenic models of Alzheimer’s disease.
  • Selective manipulation of mesocorticolimbic structures using viral-mediated gene transfer and DREADD technology

Profile:

Research in my laboratory utilizes behavioral, pharmacological, biochemical, imaging and genetic techniques to examine the neurobiological mechanisms underlying drug abuse, mood and anxiety disorders, and Alzheimer’s disease, including the critical role of stress. Prolonged exposure to excessive or uncontrollable stress represents a common risk factor for these neuropsychiatric disorders. My goal is to utilize these neuroscience techniques to identify the brain systems dysregulated in these neuropsychiatric disorders in order to develop novel pharmacotherapies.
