Biography: Dr. Kaushal Kishor Prasad (KKP) is Professor and Chief of the Division of Gastrointestinal Histopathology in the Department of Superspeciality of Gastroenterology at Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India. KKP has modified the Marsh-Oberhuber classification of celiac disease, developed the grading system of histological lesions in celiac disease; histological scoring and grading system of lesions in ulcerative colitis; coined the term “Follicular esophagitis” for a novel histopathological entity in esophagus" and developed the rice based gluten-free composite flour cookies for celiac disease patients. His main research areas of interest are celiac disease, microscopic colitis, extrahepatic portal vein obstruction and inflammatory bowel disease. KKP is in international editorial board member for more than 60 international journals and reviewer for more than 110 international journals. He has received 32 awards in international and national scientific forums including V R Khanolkar and S R Naik award. KKP has authored 93 papers and has contributed 15 book chapter/ books in the field of Gastroenterology. KKP has published 16 papers on celiac disease in international journals of high repute and 3 articles in national journals. He had completed several research projects and he is member of ICMR expert group to review of research project proposals for extramural grant. Under his guidance 26 students (MD, PhD, MCh & DM) awarded their respective degrees and students has ongoing dissertation work. KKP has visited across the globe (more than 25 countries) to deliver invited lectures and to present scientific papers. He is life member/ member of 20 international and 11 national professional societies and holding key posts in several societies.
