Research Interests

My research centers on ecology in the broadest sense, with a large emphasis on conservation issues and the increasingly profound impacts of humans on the environment, including urban ecosystems and international development. The ethics of such research is also an interest. Much of my work is carried out on reptiles and amphibians, and invasive species are a common focus. My research is primarily conducted in the field and typically focuses on the whole organism and its interactions with its biotic (including human) and a-biotic environment. Whenever possible, I use multiple methods, and this integrative approach has led to continuously-evolving research spanning varied sub-disciplines.


I serve as a Section Editor for Reptiles & Amphibians and a member of the Invasive Species and Iguana Specialist Groups of the IUCN. I am also the Senior Director of the Division of International Research and Development at the Office of International Affairs and the Director of the International Center for Arid and Semi-Arid Land Studies
