Dr. Cossel has had a lifelong interest in studying organisms in their natural environments and has always been drawn to the “creepy crawlies” of the animal kingdom, particularly the combined taxa of amphibians and reptiles (herpetofauna). At the Quetzal Education Research Center, Dr. Cossel teaches the Herpetology module of our Tropical Ecology and Sustainability Course. He also leads a herpetology research project each semester.

The education/conservation outreach efforts of Dr. Cossel’s lab group includes the design and installation of a rainforest exhibit (See a video clip) that is the best of its kind in the northwest. This and other live animal exhibits see over 1,000 visitors annually. Dr. Cossel is also an accomplished photographer with photographs appearing in magazines, books and in a curated photo exhibit called Naked Canaries that traveled to various universities (including a visit to Southern Nazarene University).
