David's background is in invasive species invasive species
An invasive species is any plant or animal that has spread or been introduced into a new area where they are, or could, cause harm to the environment, economy, or human, animal, or plant health. Their unwelcome presence can destroy ecosystems and cost millions of dollars.

Learn more about invasive species and physiological ecology. He is interested in how organisms and populations respond to ecological challenges induced by human activity. David worked for 12 years as our Southwest Region's Aquatic Invasive Species Coordinator before moving to San Marcos to work with threatened and endangered species.

David completed a Bachelors of Science degree in Zoology from Northern Arizona University. He earned a Master of Science degree in Biology from the University of Texas at Arlington, examining bioenergetic resource allocation in pond snails exposed to thermal stress. He began his coursework for a Ph.D. at the University of Hawaii in Manoa, where he studied invasive apple snails, but returned to Texas to complete his Ph.D. in Quantitative Biology from the University of Texas at Arlington. His dissertation focused on adaptation in a population of Western Mosquitofish in response to warming temperatures.
