Dr. Christopher Raxworthy has been studying reptiles and amphibians in Madagascar since 1985. Currently, his research is focused on gecko and chameleon molecular and morphological systematics, and the use of remotely sensed data (from satellites) to help predict the distributions and model the ecological niches of species. This project includes field surveys of mountainous areas of northern Madagascar, many never previously explored or surveyed. Dr. Raxworthy also has conducted fieldwork in Vietnam, Ghana, and Mali. His broader research interests include the applications of Geographic Information Systems (GIS) for identifying conservation priorities, and exploring patterns of speciation and endemism in Madagascar.
