Dr. Banikalyan Swain obtained his Ph.D. in Biotechnology from Utkal University in 2015, Bhubaneswar, India. He joined University of Florida as a Postdoctoral Associate in 2015. Currently he is working as a Research Scientist in Department of Infectious Diseases and Immunology, University of Florida. Dr. Swain focused on innate and adaptive immune mechanism of fish and he has published his research in different reputed peer reviewed journals. He is working on the design, construction and evaluation of genetically modified derivatives of Edwardsiella piscicida, as vaccine vectors to deliver protective antigens encoded by genes from other pathogens as well as DNA vaccines encoding such protective antigens. Dr. Swain and his group has designed a regulated delayed attenuation and programmed self-destructing Edwardsiella piscicida strains that efficiently colonize fish lymphoid tissues, allow release of the bacterial cell contents after lysis and exhibit complete biological containment. These technologies are being used to reduce morbidity and mortality caused by bacterial, viral and parasite infectious disease agents of fish.
