​Dr. Castillo  graduated from the Universidad Autonoma de Chihuahua with a B.S. in Ecology. He later got a Ph.D. in Microbial Ecology from Penn State University studying the changes in microbial communities in wastewater treatment systems. After that the returned to his old school where he taught several chemistry and microbiology courses and set up a laboratory to study ways to improve forage digestion in dairy cows by manipulating the microbial communities in their rumen. More recently, he spent several years at New Mexico State University, including close to 1000 hours at an underground laboratory, where he focused his research on studying the effects of ionizing radiation on cellular gene expression. He currently is starting a Radiation Biology Lab at the Human Factors Department where he’ll continue exploring how organisms adapt their genome’s expression in response to fluctuating amounts of radiation at the International Space Station, and beyond.
