Dr. Kaushal Kishor Prasad (KKP) is Professor 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 is in the panels of experts for the World Association of Societies of Pathology & Laboratory Medicine (WASPaLM), and SAARC Academy of Cytopatology & Histopathology (SACH). KKP has modified the Marsh-Oberhuber classification of celiac disease, developed the grading system of histological lesions in celiac disease, 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. KKP is reviewer for the extramural including ICMR and intramural research project proposals especially on celiac disease. His main research areas of interest are celiac disease, microscopic colitis, extrahepatic portal vein obstruction and inflammatory bowel disease. He published sixteen articles on celiac disease in international journals of high repute and three articles in national journal. KKP is international editorial board member for more than 30 international journals and reviewer for more than 60 international journals. He travelled across the world and delivered invited lectures and presented more than 160 scientific papers in more than 100 conferences.
