Mark C. Urban is an award-winning scientist, professor of ecology and evolutionary biology at the University of Connecticut, founder and director of the Center of Biological Risk, and global expert on climate change impacts on nature and evolutionary ecology. An avid field biologist, Mark takes every opportunity to get out in the field to learn about the diversity of life and its threats. He routinely spends time in ponds, lakes, and streams in regions ranging from New England to the North Slope of Alaska. He founded and directs the Center of Biological Risk, the first center devoted to forecasting the complex risks to society mediated by ecosystems. He has authored over 65 scientific articles, appearing in top journals such as Science, Proceedings of the National Academy of Sciences, and Nature Climate Change and has been cited more than 8500 times. By integrating ecology, evolution, and genomics, his work has uncovered new principles that routinely challenge existing ideas, including challenging the spatial scale of adaptation, the importance of adaptation in ecology, and highlighting the joint ecological and evolutionary responses to global change. Most recently, his work has focused on designing global efforts to estimate and mitigate extinction risks from climate change on biodiversity.
