Research Specialty
Our research program focuses on the role of endocannabinoids in stress-induced neuroadaptation.

Research Description
Psychosocial stress is a key trigger for the development and exacerbation of a variety of psychiatric disorders including depression, addiction, schizophrenia, and post-traumatic stress disorder. By understanding the molecular, structural, and physiological adaptations in endocannabinoid signaling that occur in response to stress, we hope uncover novel bio-markers and pharmacological targets for drug development. In addition, we hope these investigations will provide insight into the pathophysiology of stress-related neuropsychiatric disorders. We use a variety of techniques including electrophysiology, mass spectrometry, protein biochemistry, genetic models, and functional anatomical studies, to understand the role of endocannabinoids in the brain's response to stress.
