Current Research Projects

  • Elucidating the regional specificity of dopamine's control over cue-elicited behaviors

  • The acute and long-term effects of stress on dopamine release and behavior

  • Neural circuits mediating changes in subjective preference

  • Delineating astrocyte-neuron interactions within the ventral midbrain and the influence of midbrain astrocytes on behavior


  • Dopamine's role in changing subjective preference (R21; DA042362)

  • Targeting astrocytes as a novel strategy to reduce cocaine self-administration (San Antonio Life Sciences Institute)

  • Role of KCNQ (“M-type”) K+ channels of dopaminergic neurons as key regulators of cocaine addiction (Addiction Research, Treatment & Training Center of Excellence)
