Summer school 2018 faculty

Professor Til Stürmer
Til Stürmer is professor, head of the Pharmacoepidemiology Program, and director of the Center for Pharmacoepidemiology in the Department of Epidemiology at University of North Carolina Gillings School of Public Health.
Til is an internist/epidemiologist with over 20 years of experience of analyzing beneficial and harmful effects of medications using nonexperimental designs.

Over the last 10 years, he has evaluated state of the art nonexperimental CER methods and developed new ones funded through an ongoing R01 on “Propensity scores and preventive drug use in the elderly” (AG023178).
Currently, Til is assessing the value of two increasingly used analytic strategies to control for confounding in nonexperimental research: propensity scores and disease risk scores. Propensity score techniques are increasingly used and Til’s work has demonstrated some advantages over multivariable outcome models when used to define comparable study populations.

Based on prior work on correction for measurement error, Til has developed a combination of propensity scores and regression calibration to control for unobserved confounders using data from an external validation study. He has also proposed and evaluated another method to reduce bias when estimating treatment effects due to unmeasured frailty leading physicians to override usual treatment decisions in patients that are very sick (frail, i.e., close to death) by excluding various proportions of patients treated contrary to prediction. As a sensitivity analysis this method can help to quantify and reduce the effect of unmeasured confounding on treatment effect estimates. Along the same line, he has recently published a model predicting frailty based on healthcare claims data.

Til is visiting professor at Department of Clinical Epidemiology, Aarhus University.

Assistant professor Jennifer Lund
Jenny Lund is an Assistant Professor in the Department of Epidemiology at the Gillings School of Global Public Health at the University of North Carolina at Chapel Hill (UNC), as well as a faculty member of UNC’s Center for Pharmacoepidemiology and the Lineberger Comprehensive Cancer Center. Through her training, Jenny has developed a broad set of analytic tools, including focused training in health services research and advanced epidemiologic methods and their application to study the utilization and impact of cancer therapies in older patient populations.

She has also amassed vast experience in working with large administrative databases in a variety of disease settings both in the United States and Denmark. Her primary research interests address health-related issues relevant to older cancer patients, including the role of multimorbidity, disability, and frailty in cancer treatment selection and outcomes, the effectiveness and safety of cancer treatment options, and the quality of care delivered. The ultimate goal of her research program is to improve the delivery of medical care and the quality of life for older cancer patients.

Jenny is visiting scientist at Department of Clinical Epidemiology, Aarhus University. 

Professor Olaf Dekkers
Olaf Dekkers is a professor at the departments of Clinical Epidemiology and Endocrinology at Leiden University Medical Center, The Netherlands. He studied medicine philosophy and graduated (MA) on the ‘truth definition according to Frege’. He was trained in epidemiology (MSc) at the London School of Hygiene and Tropical Medicine. 

Research topics are epidemiology of endocrine diseases, meta-analysis and methodology of research. He works in close collaboration with the Institute of Social and Preventive Medicine in Bern (Switzerland) on and with the Department of Clinical Epidemiology in Aarhus (Denmark). He is methodological chair of the guideline committee of the European Society of Endocrinology.

Olaf is adjunct professor at Department of Clinical Epidemiology, Aarhus University.

Professor Irene Petersen
Irene Petersen is Reader in Epidemiology and Statistics at the Department of Primary Care and Population Health, UCL, London. Her focus is on epidemiological and methodological research arising from electronic health records including studies in pharmacoepidemiology, infectious disease, mental health and cardiovascular disease, missing data and issues around confounding.

Irene is part-time Professor at Department of Clinical Epidemiology, Aarhus University.

Professor Vera Ehrenstein
Vera Ehrenstein received a Master of Public Health in Epidemiology and Biostatistics and a doctorate in epidemiology from Boston University School of Public Health.

Vera coordinates the pharmacoepidemiology research program at the Department of Clinical Epidemiology. She has led postmarketing investigations of medicinal agents, including studies commissioned by the European Medicines Agency.

Vera’s own academic interest is in perinatal and reproductive epidemiology, including study of drug use in pregnancy. She is the curriculum coordinator for the PhD program in Clinical Medicine at Aarhus University, and she teaches a course on scientific writing and peer review.
