Professional Interests

My two active areas of research are in the areas of amphetamine-induced monoamine neurotoxicity (i.e., MDMA, Methamphetamine, ephedrine or amphetamine-induced monoaminergic neurotoxicity), and the neurobiology of anxiety disorders.  Methods used in both research spheres include neuropharmacology, PET, MRI, fMRI, polysomnography, pharmacological challenge, and neuropsychiatric assessment.  Studies of amphetamine neurotoxicity also include preclinical studies using microarrays, cell culture, rodents and primates.
