I have directed students to completion of masters and doctoral degrees in studies of the systematics and ecology of both amphibians and reptiles. My special research interest for over 30 years has involved all aspects of the biology of lizards of the genus Aspidoscelis (Cnemidophorus) found in the United States, Mexico, Central America, and South America.
