Paul Cryan, PhD
Paul Cryan is a Research Biologist at the Fort Collins Science Center.
Mysteries, underdogs, and gadgets have always fascinated me, so for the past two decades I have focused my research on using technology to reveal how some of the 43+ species of U.S. bats live their cryptic lives. My particular interests include uncovering bat migration behaviors and seasonal movements, discovering the details of their winter hideouts and survival strategies, and understanding how infectious diseases influence bat populations. What began as general interest in an understudied group of mammals has grown into a practical search for answers to two of the most pressing threats currently facing U.S. bats - fatalities at wind turbines and the emerging disease known as white-nose syndrome. My basic research approach is to start by synthesizing natural history and existing information, then test plausible new hypotheses in a scientifically defensible way through observational and experimental field studies. I gravitate toward new collaborations and technologies that take us beyond existing methods and expand our abilities to follow and discover what (and how) bats are doing out there in the dark.
