Education and Training

I graduated from the University of Pennsylvania with a B.A. in Biology and German and received my M.D. at Temple University School of Medicine in Philadelphia. I trained in Internal Medicine at Johns Hopkins Bayview when it was still called Francis Scott Key Hospital, and then earned a Master of Public Health as part of my Occupational Medicine residency at Johns Hopkins School of Hygiene and Public Health. I also have a certificate in Instructional Design from the University of Wisconsin. I am board certified in Internal Medicine and Occupational Medicine. 


I joined the University of Maryland School of Medicine faculty in 2017 as an Associate Professor of Medicine in the Division of Occupational and Environmental Medicine. In this role, I participate in clinical surveillance of a cohort of Veterans exposed to depleted uranium and serve as Medical Director for the Building Trades National Medical Screening Program, which serves a cohort of 28,000 former construction workers at Department of Energy sites. I also provide employee health related services to the University of Maryland Faculty Physicians, Inc., University of Maryland, Baltimore and University of Maryland, College Park. I coordinate the educational rotations for residents from University of Maryland, Johns Hopkins and the Uniformed Services University of the Health Sciences, and serve as the Faculty Advisor for the UMSOM medical student special interest group for Preventive, Occupational and Environmental Medicine.

My research interests focus on preventing avoidable work disability, which led me to study the challenges facing individuals with opioid use disorder. In 2018 I mobilized an interdisciplinary team of researchers, which received two grants in 2019 (the Institute for Clinical Translational Research (ICTR) Accelerated Translational Incubator Pilot (ATIP) grant and the Center for Addiction Research, Education and Services (CARES) Science to Systems grant) to study the work status and barriers to work in patients receiving Medication Assisted Treatment for Opioid Use Disorder in UMB clinical centers. This is the first phase of a planned multiphase project to develop and research interventions to increase work participation in this vulnerable population.

Other research interests are risk factors for prolonged work disability, the content and quality of physician/patient communication, return-to-work and workers’ compensation policy and clinical education. A recent research project for the Maryland Department of Health evaluated the effectiveness of a short online educational module in modifying physician use of the Prescription Drug Monitoring Program.

I am a member of the UMMS Opioid Stewardship Task Force and the Maryland MedChi Opioid Task Force. I am an elected Fellow in the American College of Occupational and Environmental Medicine (ACOEM) and the American College of Physicians (ACP). I served two terms on the ACOEM Board of Directors and am the former chair and current member of ACOEM’s Council on Occupational and Environmental Medicine Practice. I am also a member of ACOEM’s Council on Education and Academic Affairs. I am the Course Director and creator of an eight-hour continuing medical education online course for ACOEM, entitled Getting Your Patients Back to Work. I serve as chair of the Johns Hopkins Occupational Medicine Residency Advisory Committee/Program Evaluation Committee. I led the ACOEM committee that developed the 2014 recommendations for clinical competencies in Occupational and Environmental Medicine.

Research/Clinical Keywords

Grants and Contracts

I recently completed a project funded by the Centers for Disease Control and Prevention (CDC) via the Maryland Department of Health to create a training module about the Maryland Prescription Drug Monitoring Program (PDMP) and evaluate its impact on opioid-prescribing providers’ attitudes and behaviors. 

Shortly after my arrival at the School of Medicine, I mobilized a group of internal and external stakeholders and researchers who would be interested in working together to improve work participation among patients receiving MAT for Opioid Use Disorder. Joining forces with Dr. Jodi Jacobson Frey in the School of Social Work, I developed a project plan for “Operation PROSPER – Peer Reintegration and Other Services Promoting Employment in Recovery,” which will be a multiphase project to study the impact of interventions delivered primarily by peer specialists in increasing work participation among MAT patients. In 2019, we were jointly awarded two grants: an Accelerated Translational Incubator Pilot (ATIP) grant from the Institute for Clinical and Translational Research (ICTR) and a University of Maryland Center for Addiction Research, Education, and Service (CARES) Science to Systems pilot grant. These will support phase one of Operation PROSPER, collecting data about the work status, interests and barriers to work among patients receiving MAT at University of Maryland Baltimore treatment centers.
