Douglas Wiebe, PhD

Professor |
Center for Clinical Epidemiology & Biostatistics | Department of Biostatistics, Epidemiology and Informatics, University of Pennsylvania

My interests include environmental risk factors for injury, methodological challenges of activity pattern measurement, the impact of daily routines on health-related behavior, and the influence of geography on health and systems of healthcare. I received my PhD from the School of Social Ecology at the University of California at Irvine and completed postdoctoral studies in injury epidemiology at the School of Public Health at the University of California at Los Angeles. I teach a course on measurement principles (EPID 542) and a course on geography and health (PUBH 517/EPID 518). I received the Teaching Award in the Masters of Science in Clinical Epidemiology Program in 2008/09, and in the Perelman School of Medicine I received the Dean’s Award for Excellence in Basic Science Teaching in 2012.

I have secondary appointments in the Department of Emergency Medicine and in the Division of Traumatology and Surgical Critical Care in the Department of Surgery in the Perelman School of Medicine. From 2009 to 2014 I held an appointment of Visiting Scholar in the Department of Geography at the University of Cambridge, England. My leadership positions include being Director of the CDC-funded Penn Injury Science Center ( and directing a training program funded by the Fogarty International Center at the NIH to build injury epidemiology capacity in Botswana. Also I am a Past President of the Society for Advancement of Violence and Injury Research (SAVIR).


Alexis Zebrowski

Alexis Zebrowski

Fourth year PhD student |
I am a fourth year doctoral student in Epidemiology. I am developing a new measure for the intensity of trauma care and investigating how intensity of care varies by patient characteristics, across hospitals, and relates to outcomes. I will be presenting this work at the Academy Health annual meeting in Seattle, WA in June 2019. I also coordinate subject recruitment activities for the Space-Time Study of School Safety.

Alexa Yakubovich, MSc

Visiting Summer Scholar |
I am a Rhodes Scholar and doctoral student in the Department of Social Policy and Intervention at the University of Oxford. I am interested in the social, economic, and psychological determinants of health and well-being among marginalized populations and developing and evaluating ameliorative programs. My dissertation research investigates whether and how community and structural disadvantages increase the risk of intimate partner violence (IPV) against women. To carry out this work, I conducted a global systematic review of the risk and protective factors for IPV that was published recently in AJPH. I am now analyzing the effects of exposure to community and structural disadvantages on the risk of experiencing IPV using quantitative data from the Avon Longitudinal Study of Parents and Children.

Darcy Ellis, MPH

Second year PhD student |
I received my MPH in Public Health from Columbia University and I am in the fourth year of the doctoral program in Epidemiology at U Penn. As part of the graduate student rotation series, I analyzed data from the Space-Time Adolescent Risk Study to estimate the duration of induction periods for activities and locations as they relate to the likelihood of being assaulted during daily activities. I presented this work at the 2017 Society for Epidemiologic Research meeting in Seattle, Washington.

Bernadette D’Alonzo, MPH

Research Coordinator |
I completed my MPH at Penn in 2017 and have worked for several years as a research coordinator. I currently manage multiple federally funded studies centered around issues of geography and health. Much of my work involves the collection and integration of data that are derived from multiple sources at different temporal and spatial scales. Also I coordinate research activities and I lead analyses for the epidemiology study of the Ivy League/Big Ten Concussion Consortium. We recently published a description of this study at Injury Prevention.
