Dr. Siddhartha Thakur is an Associate Professor in the College of Veterinary Medicine at NC State University. He is the Associate Director at the Comparative Medicine Institute where he leads the Emerging and Infectious Diseases Research program. He received his Veterinary Science degree and Master in Veterinary Public Health from India. He earned his Ph.D. in Population Medicine at the College of Veterinary Medicine, NC State University. Prior to joining the faculty at NC State University, he was an Oakridge Research Fellow at Center for Veterinary Medicine, FDA, Maryland. Dr. Thakur espouses the concepts of “One Health” and uses its principals to study the impact of interplay between animals, humans and their environment on the dissemination and persistence of antimicrobial resistant bacterial strains. He was awarded the Larry Beuchat Young Researcher Award by the International Association for Food Protection in 2012 and is a NC State Chancellor faculty scholar. Dr. Thakur has authored or co-authored 35 peer reviewed publications. His lab consists of three PhD candidates (including one funded through the T32 grant and another through the USDA0NIFA training grant), one visiting scientist from China and an ORISE fellow.
