Overall, my research focuses on using the neuroimaging methods MRI and PET to study the neurobiology underlying disease in humans. My recent work includes using diffusion-based MRI to study putative neuroinflammation associated with obesity. Other disease states of interest include psychiatric diseases and substance use disorders. I am also interested in exploring the impact of the interaction between genetics and brain structure and function on obesity and psychiatric conditions. I hope to discover aspects of brain structure and function that can be targeted for drug therapy and/or prevention of these conditions.
