I have returned to Johns Hopkins after a 12-year hiatus.  My research on mental health in community settings including primary health care has incorporated mixed methods (i.e., methods derived from both epidemiologic and anthropologic traditions). I co-wrote a chapter on funding and publishing mixed methods studies for the Second Edition of the Handbook of Mixed Methods in Social & Behavioral Research (Sage Publishers, 2010). I am on the editorial boards for the American Journal of Geriatic Psychiatry, the International Journal of Psychiatry in Medicine, and the Journal of Mixed Methods Research. I am a standing member of an NIH panel, Community Influences on Health Behavior.

I was the Project Director for the 13-year follow-up of the Baltimore sample of the NIMH Epidemiologic Catchment Area Program. Prior work includes publications on risk factors, course, and epidemiology of psychiatric disorders, the form of depression in late life, health services research in mental health, the co-morbidity of depression and medical conditions, primary health care and mental health, cognitive impairment, and methodology. I was the PI for the “Spectrum of depression in late life,” a group of linked mixed methods studies to investigate depression in late life. I am also PI for the PROSPECT follow-up ("Long term outcomes of depression in late life"). PROSPECT was an intervention trial of depression care management in primary health care, and we are now using claims and death data to study the long-term outcomes of improved depression treatment. I received a Fogarty International Research Collaborative Award to study depression among older adults recruited from primary care practices in Mexico City.

I am developing a course on medical comorbidity and mental health, and would like to develop programs around mental health services research and mixed methods.

Honors and Awards

In recognition of my mentoring ability, I was awarded an NIMH Mid-Career Investigator Award in Patient-Oriented Research (K24) and in 2008 I was the first recipient of the Steven Banks Award for mentoring in public mental health from the American Public Health Association.
