Dr. Alejandro (Alex) Castillo is associate professor in the Department of Animal Science. He is also a member of the Intercollegiate Graduate Faculty of Food Science and Technology, and chair of this faculty since May of 2010. He teaches the graduate course in Microbiology of Foods at Texas A&M University. Before joining the Texas A&M faculty in 2002, he was a professor in the Department of Biology and Pharmacy at the University of Guadalajara, Mexico. Alex has taught courses in food safety at the graduate level as guest professor at the University of Buenos Aires in Argentina, the University of Guatemala Valley in Guatemala and the University of Central America in Nicaragua.

Alex’s research interests include the development of control measures for minimizing and reducing pathogens in fresh and fresh-cut produce and on beef carcasses, the prevalence of pathogens in fresh produce and the use of electron beam irradiation for food safety purposes. He has published numerous articles in peer-reviewed journals, has authored or co-authored 6 book chapters and has published two books as editor.  Is active member in various professional organizations and assists as reviewer in different scientific journals.
