The research carried out in the course of my work is mainly concerned with: the history of veterinary medicine, and the welfare of wild and zoo animals. An additional aspect is veterinary epidemiology. My research on the history of veterinary medicine includes veterinary pharmacy and the development of animal infectious disease control activities. The most recent line of research is animal medicine in the medieval period. For animal welfare, I am working on a project to assess the welfare of selected species kept in zoos. The research is observational and survey-based and based on protocols recommended by EAZA, WAZA.
