Dr James Van Dyke is an ecophysiologist interested how animals "work", and how they are affected by environmental disturbances, like pollution or global warming.  He applies his work to understand how animals decline as a result of environmental change. He completed his PhD at the University of Arkansas in 2011, which focused on reproductive biology of vertebrates, mainly snakes and turtles. From 2011-2012, he held a postdoctoral fellowship at Virginia Tech, where he assessed how turtles were impacted by a massive coal fly-ash spill in Tennessee, USA.  He then moved to The University of Sydney on a National Science Foundation (USA) International Research Fellowship to study the evolution and physiology of the placenta in vertebrates (2012-2014), using lizards, mammals, and sharks as model systems. From 2015-2017, he was a postdoctoral researcher at Western Sydney University, where he studied the causes of major turtle declines in the Murray River Catchment.
