Dr. John J. Wiens primarily studies the evolution and ecology of reptiles and amphibians. He received his Ph.D. from the University of Texas at Austin, and is presently an Associate Professor in the Department of Ecology and Evolution at Stony Brook University in New York. His research focuses on reconstructing trees of evolutionary relationships for species and major groups of reptiles and amphibians (including lizards, snakes, turtles, frogs, and salamanders) using data from DNA sequences. He (along with his collaborators and students) then use these trees to address general questions in evolution and ecology, such as: why are there more species in tropical regions? how do new species arise? how do species respond to climate change? and why do species diverge (or remain the same) in their anatomical and ecological characteristics over time?
