Graduate Exam Coordinator   |   Associate Professor   |   MSc, PhD (Dortmund, Germany)


I am a statistical epidemiologist working in the area of veterinary epidemiology and biostatistics. In the Department of Population Medicine I am leading the Statistical Consulting Group.

Research Interests

My principal research interest is the advancement of statistical epidemiology for clustered data in the context of veterinary and public health sciences. I focus on spatial / geographical epidemiology, and also enjoy applications of biostatistics using time series analysis, disease surveillance, meta-analysis and survival time analysis. Respective methods find applications in many commodity groups: swine, dairy cows, sheep and goats as well as cats and humans. Zoonoses are of particular importance to me, incl. West Nile virus and Echinococcus multilocularis.

Recent graduate student projects investigated "scrapie in small ruminants", "effects of heat-waves on human and dairy health", "cat overpopulation", "the historic cholera epidemic in Ireland of 1849/50", and "private well water safety".

I am very interested in the History of Statistical Epidemiology, as well as its future: Open Science and Reproducible Research.
