    Research Summary

    My broad clinical and preclinical expertise is the application of behavioral pharmacology and behavioral analysis to a scientific investigation of mood-altering drugs. Areas of specialization include hallucinogens and novel “club drugs”, caffeine self-administration, withdrawal and addiction, sedative self-administration and sedative effects, cigarette smoking and nicotine self-administration, alcohol self-administration, and baboon drug self-administration and drug discrimination.
