Amphibians, Reptiles, & Natural History

Naturalist, Photographer , Zoologist
After retiring from a career teaching biology and anatomy & physiology and science administration, I study reptiles and amphibians (but focus mostly on squamates). My current interest are in snake phylogeny and diversity, highly aquatic snakes (that are non-sea snakes), the herpetofauna of Trinidad and Tobago, and giant snakes. I have been on the Board of Directors of the Chicago Herpetological Society, the Board of Directors of the Tucson Herpetological Society; a research associate at the Field Museum in Chicago. I have been a member of the International Union for the Conservation of Nature’s (IUCN) Snake Specialists Group International Society for the History and Bibliography of Herpetology (ISHBH); and on the board of directors of Friends of Madera Canyon.
