Dr. Hilario Mantovani received an M.S. degree in Agricultural Microbiology from the Federal University of Viçosa (UFV) and earned a Ph.D. degree in Microbiology from Cornell University under the mentorship of the late James B. Russell. Dr. Mantovani developed several academic and scientific activities in Brazil as a faculty member of the Department of Microbiology at UFV and was a visiting scholar at the U.S. Dairy Forage Research Center. He mentored more than 40 graduate and 20 undergraduate students and served for five years as Coordinator of the Graduate Program in Agricultural Microbiology (UFV). Dr. Mantovani joined the Department of Animal and Dairy Sciences at the University of Wisconsin-Madison in 2022.

Dr. Mantovani’s research program is focused on understanding the functions and ecological interactions between anaerobic microbes that colonize the gastrointestinal tract of ruminants. Currently, special attention is given to screening and discovery of new bioactive molecules (notably AMPs) against bacterial pathogens and archaea (methanogens) and the development of microbiome-derived technologies (e.g., bioactive molecules, probiotics, inoculants) for animal health. His research group examines fundamental and applied questions related to the ecology, physiology, and genetics of rumen microbes aiming to unveil their roles in rumen function and host phenotypes. Dr. Mantovani’s research also seeks to understand the mechanisms and drivers of antimicrobial resistance and explore livestock microbiomes for biotechnological purposes, including alternatives to antibiotics. The research goal is to generate knowledge and develop approaches to improve animal health and productivity, promote food safety and enhance the environmental sustainability of livestock production.
