Hanno Würbel, Dr.sc.nat, has studied biology (zoology) at the University of Berne (Switzerland) and graduated from the ETH Zurich (Switzerland) in 1996 with a thesis on the development of stereotypies in laboratory mice. Funded by the Swiss National Science Foundation he continued research on stereotypies in mice as a postdoc in the group of Christine Nicol at the University of Bristol (UK). Back at ETH Zurich, he started to develop a research program on environment-dependent plasticity of brain and behavior in relation to questions of animal husbandry and animal welfare. In 2002, Hanno moved to Giessen (Germany) to take up the chair in Animal Welfare and Ethology at the University in Giessen. For his research on environmental enrichment and standardization in animal experimentation he received the Hessian Animal Welfare Research Award (2005) and the Felix Wankel Animal Welfare Research Award (2009). He is a member of the Animal Welfare Council of the German government, Central Animal Welfare Officer of the University of Giessen, and head of the University's Central Animal Facility. He has served on the ILAR committee of the US National Academies for the recent update of the 'Guide for the Care and Use of Laboratory Animals', is a council member of the International Society of Applied Ethology (ISAE), editor of the Journal of Applied Animal Welfare Science, and editorial board member of the journal Applied Animal Behaviour Science.
