John Roe joined the Hopkins laboratory as a research technician after completing his undergraduate degree at Davidson College. After working with us for 2 years, he left for Indiana University Purdue to obtain his MS degree. He then rejoined the Hopkins laboratory for more than a year before heading to Australia to pursue a Ph.D.

John completed his Ph.D. in 2008 from the University of Canberra. Currently, Dr. Roe is a Professor at the University of North Carolina at Pembroke. His research focuses on how an organism’s physiology, behavior and life history traits relate to their ecology, evolution and ultimately, to their conservation. By examining these types of questions, John hopes to gain a better understanding of how organisms have adapted to their environments, and how they continue to interact with the continually changing environments. In particular, he is interested in investigating the biology of aquatic and semi-aquatic reptiles and amphibians to address these questions, because these organisms have an especially dynamic interaction with their habitat. The fact that wetlands are being drained, polluted or otherwise altered from a natural state at an increasing rate puts the organisms that rely on such habitats in danger.

While a technician in the Hopkins laboratory, John worked on a variety of projects pertaining to amphibian and reptile physiology and conservation.
