Gregor Majdic is Professor of Physiology at the University of Ljubljana Veterinary school and Professor of Physiology at the University of Maribor Medical School in Slovenia. His main scientific interest is how genes and hormones influence the development and function of the brain, and especially how brain function is related to behavior. He also studies adult stem cell treatments in animals and funded a start-up company Animacel, which provides stem cell treatments for animals in several European countries. After graduating from the Faculty of Veterinary Medicine at the University of Ljubljana, his passion for knowledge led him to pursue a scientific career at the University of Edinburgh, Scotland, and at the University of Texas Southwestern medical school in Dallas, Texas, before returning to his native Slovenia. He has published more than 80 peer-reviewed scientific articles. He is a member of several international scientific societies and has lectured at many universities in Europe, the USA and Asia. For his development of stem cell therapies in animals, he was awarded two prestigious national awards for the best innovations in the public sector in Slovenia. He has written numerous popular science articles for various Slovenian newspapers/magazines and is a regular guest on radio and television programs about science. He is also the author of three published books, two fictional historical novels (Gabriel's Passion and White Saracen) and a popular science book for younger readers, Secret of Life, which describes the understanding of sex determination in various cultures throughout history. Above all, Gregor is devoted to his family, his wife Nada, his son Jakob and his daughter Hana. Together they love to travel around the world (on their own and off the beaten track), to cook, play, laugh and be active in nature; they like rock climbing, mountaineering-skiing, mountain biking, kayaking, scuba diving and other outdoor sports.
