Research Summary
Our group has been studying the treatment and pathophysiology of schizophrenia. Our work involves the use of various psychopharmacological probes (ketamine, delta-9-THC, iomazenil, etc) to evaluate the contributions of various neurotransmitter systems (NMDA, cannabinoid, GABA, etc) to the pathophysiology of schizophrenia; laboratory studies of comorbid substance abuse in schizophrenia, (alcohol, cannabis and nicotine) and clinical trials with novel agents for schizophrenia.
