Ravi Kulkarni

Asst Professor

CVM Main Building NA


Dr. Ravi Kulkarni joined the College of Veterinary Medicine, North Carolina State University in January 2019 as an Assistant Professor in the Department of Population Health and Pathobiology. Dr. Kulkarni obtained his BVSc (eqv. DVM) from Karnataka Veterinary, Animal and Fisheries Sciences University, India, and Masters in Parasitology and Immunology from Indian Veterinary Research Institute. Subsequent to working in the pharmaceutical industry (Drug Discovery, Torrent Research Center) for a few years in India, he joined University of Guelph, Ontario Veterinary College, Canada, to pursue his PhD in the area of immunology and microbiology. Following his PhD, he did his post-doctoral training in avian immunology for two years with a fellowship supported by the Ontario Ministry of Research and Innovation, Canada. Subsequently, to gather further training in vaccine immunology and microbiology, he worked at the Emory University Vaccine Center, Atlanta, Georgia, for three years. He once again joined University of Guelph, Department of Pathobiology, as an Adjunct professor and Associate graduate faculty to research in the areas of avian health, disease and vaccines. He also served for three years as the Research Coordinator for the Poultry Health Research Network (PHRN) at Guelph.

Kulkarni laboratory focuses on studying ‘host-microbe interaction’ with a focus in the areas of immunology, microbiology, Probiotics and vaccines that are crafted into on three major research programs:
1. Improving gut health and developing alternatives to antibiotics:
The traditional use of antibiotics as feed supplements to control enteric infections in poultry production has come under greater scrutiny in recent years. While this has pushed the industry to grow birds without antibiotics, it also has caused increased spikes in the incidences of enteric diseases. My laboratory focuses on studying three such diseases that have severe economic impacts on the poultry industry. These are Necrotic enteritis (NE) caused by Clostridium perfringens, Clostridial dermatitis (CD) caused by Clostridium septicum and Coccidiosis caused by Eimeria protozoa. The two specific research areas related to this topic are:
i. Understanding immune responses against Clostridial and Eimeria pathogens:
ii. Probiotics and Vaccines against NE and CD:

2. Viral immunology and boosting vaccine-induced immunity in poultry:
Understanding immunity to viral diseases and mechanisms to boost virus-induced immunity in poultry enables advanced research-based intervention strategies for effective disease control. Kulkarni laboratory studies virus/ vaccine-induced responses against Marek’s disease (MD) and Infectious Laryngotracheitis (ILT) in chickens. This work also includes identifying molecular adjuvants to boost MD and ILT vaccine-induced responses.

3. Precision Health technologies:
Precision Livestock Farming in poultry production is on the rise in recent years targeted at early detection of diseases using sensor-based tools. Through collaboration with Ag- engineering faculty at CALS-NCSU, Kulkarni laboratory works on developing sensor-based precision tech tools to detect volatile organic compounds (VOC) released in the air during early disease development of necrotic enteritis, coccidiosis and clostridial dermatitis in poultry.
