Welcome New Faculty!
Michelle Calvo-Lorenzo comes to OSU from the University of California, Davis where she received both her M.S. (2008) and Ph.D. (2012) degrees in the Department of Animal Science. She received her B.S. (Biology) in 2005 from Florida International University. Dr. Calvo-Lorenzo joined the OSU faculty in 2012 as the department’s animal behavior and well-being specialist. She will teach courses surrounding the topics of livestock behavior, handling, and welfare. Dr. Calvo-Lorenzo will conduct research on improving practical tools, management strategies, and environmental conditions that optimize animal well-being and behavior. Topics of interest include assessing heat stress, housing, transportation, and pain alleviation using current practices to help producers develop practical and sustainable systems of the future. Divya Jaroni joined the department as an assistant professor in January of 2012 after five years as an assistant professor at Southern University, Baton Rouge, La. She holds a B.S. in Chemistry and Biological Sciences from Devi Ahilya University, India; an M.S. in Animal Science and a Ph.D. in Food Science from the University of Nebraska-Lincoln. Dr. Jaroni’s research focuses on the development of pre- and post-harvest control strategies to reduce foodborne pathogens in food animals and fresh produce; development of culture methods and rapid molecular techniques for the detection, quantification and characterization of pathogenic microorganisms; and evaluation of natural antimicrobials (direct-fed-microbials and plant-derived products) used to improve food safety at pre- and post-harvest levels. Her work has resulted in a patent and the commercialization of pre-harvest feed additives that reduce E. coli and Salmonella in cattle.

Ranjith Ramanathan comes to OSU from the University of Connecticut where he received his Ph.D. degree in 2012. He received his B.S. (Bachelor of Veterinary and Animal Science) in 2004 from Kerala Agricultural University, India and his M.S. from the University of Connecticut. Ranjith joined the faculty at OSU in 2012. He is teaching Fundamentals of Food Science, Food Chemistry, and Food Analysis. Ranjith’s research focuses on both fundamental and applied factors that influence fresh meat quality; more specifically on postmortem biochemistry and meat color. Megan Rolf joined the extension faculty at OSU in June 2012. Megan grew up on a cow/calf operation in east central Kansas near LeRoy and received her B.S. from Kansas State University (Animal Science) in 2005. She worked as a graduate research assistant at the University of Missouri where she received her M.S. in Animal Science in 2009 and Ph.D. in Genetics in 2012. Dr. Rolf’s research has focused on the use of DNA marker data for genetic evaluation of beef cattle and identification of genomic regions influencing economically relevant traits. Her extension program focuses on the management of beef cattle genetics to maximize profitability as well as education on use of genomic technologies in the beef industry.
