Biography: 

Dale DeNardo is the Attending Veterinarian and director of the Department of Animal Care and Technologies at ASU. In this role, he oversees the husbandry and health of all animals on campus.  

He is also a professor in the School of Life Sciences. His research focus is in environmental physiology where he studies the interaction between an organism and its environment. He and his research team use both laboratory and field-based experiments to investigate how physiological state, behavior, and environmental conditions interact to enable an animal not only to survive but also to thrive and reproduce in challenging environments such as deserts. Professor DeNardo and his collaborators are particularly interested in how organisms deal with limited resources, such as energy and water, and how their coping strategies will be affected by climate change.

Service: 

1. Research experience for undergraduates:  I currently have 6 undergraduate researchers intimately involves in research projects within my lab, and I have had 50 such students over the past 5 years.  Many of these students remain in the lab for over a year, and some for three years.  The students reflect the culturally diverse population at Arizona State University. 

2. Enhancement of career guidance mechanisms: Currently a faculty representative working with the School of Life Sciences advising office to revise our approach to guidance from one focusing on the acquisition of a degree to one emphasizing effective preparation for the chosen career.

3. Dissemination of scientific knowledge to the general public: Utilize the inherent curiosity of reptiles to build an appreciation for the animals, the environment, and the biological sciences.  Examples of my involvement in television documentaries, which have the broadest reach of the various mechanisms:

National Geographic: United States of Animals (2016). 30-minute show that includes a segment on our research on Gila monsters.

BBC America - Wild Things with Dominic Monaghan (2014). My research with Gila monsters featured as one of 5 Sonoran Desert topics. Airdate TBD.

Discovery Channel Canada - Daily Planet. (2010). 6-minute segment featuring our research on Gila monsters (Heloderma suspectum).  Airdate: January 20, 2010.

ASU Research Review: Tracking the Gila Monsters. 8-minute segment featuring our research on Gila monsters (Heloderma suspectum).  Airdate: November 16, 2005.

National Geographic: Reptile Wild with Dr. Brady Barr, Arizona Rattlers (2003). 30-minute show predominantly featuring our field research (mostly Gila monsters, but also western diamond-backed rattlesnakes)

Arizona Wildlife Views: Gila Monsters (2003). 10-minute segment on our Gila monster field research

Discovery Channel: Tracking Deadly Vipers (2002) – 60-minute show, with our western diamond-backed rattlesnake field research being one of six pit viper studies featured.

National Geographic: Gila Monsters (2001). 30-minute show with our research on Gila monsters being the primary focus.
