Dr. Asit Ranjan Ghosh is a Professor (Higher Academic Grade) of the Department of Integrative Biology, School of BioSciences and Technology of Vellore Institute of Technology (VIT), Vellore since 2005. He has worked in the field of diarrheal and enteric infections since 1986 leading to Ph.D. with ICMR fellowships at the ICMR-National Institute of Cholera and Enteric Diseases, Kolkata (1986-1991) under the University of Calcutta, Kolkata with the understanding of pathogenic mechanisms and molecular epidemiology of major etiologies, for their better diagnosis to enhance the rate of recovery among hospitalized pediatric subjects, in community, related environmental intervention, vaccine development with experience in molecular microbiology and immunodiagnostics. He has earlier served as Scientist B and Scientist C in ICMR-Regional Medical Research Centre, Port Blair between 1994-2003; Visiting Research Associate at Johns Hopkins School of Hygiene and Public Health, Johns Hopkins University, Baltimore, USA (1991-1993); Visiting Professor & COE Researcher at Obihiro University of Agriculture and Veterinary Medicine,Obihiro, Japan (2003-2004); Assistant Director in Centre for Infectious Diseases and Control, VIT University (2010-2015). His recent focus of research is on Gut health infection, diagnosis, and control. Gastroenteritis is an event of infection but disease like irritable bowel syndrome is because of dysbiosis. In both cases, microbial populations, especially bacteria play a key role to maintain/ disturb homeostasis. Hence, host interaction with pathogens, commensals, and probiotics are the area of research to understand their common and special behavior and to find therapeutic solutions for the control of infection, inflammation, colon cancer, and obesity. He is a member of more than 10 national and international scientific bodies and a reviewer of several Scopus-indexed journals. He has more than 18 years of teaching experience inMicrobiology, Immunology, Immunotechnology, Cell Biology, Molecular Biology, Diagnostic Microbiology, Medical Biotechnology, Probiotics Technology, Food Nutrition, and Health. He has also published more than 120 research articles in peer-reviewed international journals and authored or co-authored 12 book chapters.
