- My primary research interest is in the neuropsychopharmacology of addiction. One of the most challenging questions in the field of addiction today is what makes some individuals are more vulnerable for the development of these disorders than others. We are currently conducting a 5-year translational research study that examines neural mechanisms that may help to explain associations among impulsive personality traits, chronic stress, and risks for drug abuse in humans. The multidisciplinary team includes investigators from the University of Maryland Schools of Nursing and Medicine and the Johns Hopkins University School of Medicine. Integrative and multimodal methods include human subjects recruitment; standardized psychiatric diagnostic screening; a large battery of personality, mood, anxiety, and stress assessments; laboratory behavioral performance assessments; medical evaluations; hormonal measures; utilization of GCRC facilities; and state-of-the-art neuroimaging using [11C]raclopride positron emission tomography (PET) scans. Pilot work is also in progress to expand the methods to utilize functional magnetic resonance (fMRI) scans to examine other aspects of reward processing.
