Luis   Cruz-Martinez DVM, MSc, PhD

Assistant Professor of Veterinary Medicine

Dr. Luis Cruz-Martinez graduated from veterinary school in Costa Rica wanting to work with wildlife and conservation. Pursuing this goal, he completed a 2-yr clinical internship and a 3-yr clinical residency at The Raptor Center of the University of Minnesota. Concurrently, he studied for an MSc at the University of Minnesota focused on zoonotic diseases and conservation biology.Dr. Luis then continued towards a PhD at the University of Calgary on wildlife ecotoxicology and ecosystem health. In his current position, his teaching focuses on wildlife medicine (avian species primarily) and case-based studies. The research question he’s most passionate is: how to motivate people to change (influence human behavior) for sustainability and conservation?
