Personal Statement

​I have focused my clinical and research interests on the complex intersection of chronic medical illness and serious mental illness. I have had clinical training in both internal medicine and psychiatry, and my clinical work over the past decade has included the provision of inpatient and outpatient medical care within an urban community mental health center. Through an NIMH-funded K23 (career development award), I have investigated the prevalence of cardiovascular risk factors among veterans with serious mental illness, and the healthcare costs and disparities of this vulnerable population. My current projects include an NIDDK (R21) grant to develop and pilot test an innovative community mental health center-based team approach to the treatment of poorly controlled type 2 diabetes among outpatients with schizophrenia.
