His research interests include host-pathogen interaction, the role of pathogen sensors in intestinal inflammation and cancer, pathogenic mechanisms of inflammatory bowel disease and colorectal cancer and identifying immune checkpoints of gastrointestinal disorders that could be targeted for therapeutic intervention and drug development. He earned his Undergraduate and Master\'s degrees in Microbiology at the University of Dhaka, Bangladesh. He then joined the International Center for Diarrheal Disease Research, Bangladesh, where he studied immune responses against enteric pathogens. He did his Doctoral research in the Department of Microbiology at Kumamoto University School of Medicine, Kumamoto, Japan, where he investigated the molecular mechanisms of host defense function of nitric oxide during gastrointestinal infection caused by Salmonella typhimurium.
