Hans has been collaborating with a number of colleagues on Mesozoic terrestrial faunas worldwide. He is the author of many scientific articles in leading peer-reviewed journals and has edited or co-edited a number of books on vertebrate paleontology and paleoecology. Hans is co-author of "Triassic Life on Land: The Great Transition" (2010) and is currently working on an introduction to the evolutionary history of reptiles. He has been elected Fellow of the Royal Society of Canada and Fellow of the American Association for the Advancement of Science. Hans was also the recipient of an Alexander von Humboldt Award for Excellence in Research and Teaching (2010).Hans is keenly interested in museum management and science education. A graduate of the Museum Management Institute, he has more than ten years of senior-level experience in museum management and frequently serves as a consultant and reviewer in this field. Hans loves sharing his enthusiasm for natural history in general and paleontology in particular through lectures, writing, and blogging.
