Dr. Matthias S. Klein held postdoctoral positions at the University of Calgary, Ludwig-Maximilians-Universität München, and a faculty position at The Ohio State University before joining McGill’s Department of Animal Science. He earned his diploma in physics (equivalent to an MSc) at the Universität Regensburg, Germany, and pursued his doctorate in the field of biology at the same institution. During his studies, he discovered small-molecule biomarkers indicating the risk of ketosis in dairy cows as well as markers of human liver and kidney diseases. Dr. Klein is employing machine learning and artificial intelligence approaches for the analysis of various big data sources, including “omics” data. His current research areas include metabolomics analyses of cow’s milk to study quality and health parameters, studies of food microbial metabolism, analyses of human health, and metabolism studies of mosquito diapause.
