Physician, Professor
Primary Care - Internal Medicine
Department: Internal Medicine
I am a primary care physician, health services researcher and director of the Division of General Internal Medicine here at The Ohio State University Wexner Medical Center. I chose to specialize in primary care because I am passionate about helping patients achieve their health goals and optimize their quality of life. My expertise includes preventive services, chronic disease management, evidence-based medicine and helping patients overcome addiction.
I also focus on developing and implementing strategies to improve care delivery, in my role as co-director of the Evidence Based Practice Center at The Ohio State University College of Medicine. My multidisciplinary team and I systematically review the scientific evidence on a variety of health care and policy topics for groups making national recommendations including the Effective Healthcare Program of the Agency for Healthcare Research and Quality (AHRQ) and the U.S. Preventive Services Task Force (USPSTF). I am also co-director of the CATALYST Clinical Scholars Program, which supports and provides mentorship for clinician researchers.As a central Ohio native and graduate of The Ohio State College of Medicine, I am especially proud to help educate our future physicians. I am a professor of Internal Medicine and serve as director of the Primary Care Research Fellowship.
Please note: Not all physicians schedule patients at each listed location.
My scholarly work centers on alcohol use disorders, and I have led some of the most widely cited research on this topic. I led the federally funded STop UNhealthy Alcohol Use Now (STUN I) and STop UNhealthy Substance Use Now (STUN II) trials, which focused on strategies to increase screening, counseling and evidence-based interventions for substance use disorders in primary care settings. I have led multiple clinical trials, observational studies, systematic reviews, meta-analyses and quality improvement projects with continuous funding from multiple agencies and institutes. I am a frequent contributor to top-tier medical journals, such as JAMA.
At The Ohio State University Wexner Medical Center, we support a faculty member’s research and consulting in collaboration with medical device, research and/or drug companies because a faculty member’s expertise can guide important advancements in the practice of medicine and improve patient care. In order to provide effective management of these relationships, the University requires annual disclosures from all faculty members with external interests related to their University responsibilities.
