I have studied in Zurich and Montréal until 1994, when I received my veterinary diploma. At this time, I went to mixed practice, and started my doctoral thesis on periparturient paresis in dairy cows parallel to my work which I finished 1997. I was then research assistant at the Instiute of Animal Nutrition in Zurich, where I finished my habilitaiton on Ca metabolism in 2007. 2009 I sat and passed the exam as european diplomate of the European College of Comparative and Veterinary Nutrition (ECVCN). Since July 2012 I am Professor for Animal Nutrition and Director of the Institute of Animal Nutrition at the Vetsuisse Faculty of the University of Zurich.
