Dr. Mark Sandfoss is the local project lead for invasive species research on reptiles in south Florida.
Dr. Mark Sandfoss is a Biologist with the USGS Invasive Species and Biothreats Branch of Fort Collins Science Center and stationed in Everglades National Park. He works as part of the team in south Florida researching invasive reptiles to improve methods of detection and species management. Dr. Sandfoss is broadly interested in the physiological ecology of reptiles, primarily snakes, within the context of conservation. His previous research experiences involved both venomous and nonvenomous snakes and projects focused on many aspects of physiological ecology including water balance, reproductive physiology, immune performance, and stress physiology.
