Brief Bio:

Dr. Mulder’s CIHR-funded graduate studies focused on the role of antigens in driving GI inflammation. After residency, Daniel joined the pediatric gastroenterology clinical fellowship program at the Hospital for Sick Children where he completed a CIHR-funded postdoctoral fellowship in the laboratory of Dr. Aleixo Muise, researching translational and computational approaches to genomic analysis in the pathogenesis of inflammatory bowel disease.

Research Interests:

Dr. Mulder is a pediatric gastroenterologist who studies the effects of the immune system on the gastrointestinal tract. Inflammatory bowel disease (IBD) is a life-long chronic disease that has profound impacts on the gastrointestinal tract. IBD is becoming a major health issue with 1 in 100 Canadians projected to have IBD by 2030. IBD is believed to be caused by dysregulation of the immune system through a variety of disrupted processes. These processes and their connection to disease characteristics are complex and poorly understood. Dr. Mulder’s research program aims to use laboratory-based immunophenotyping techniques to create molecular “fingerprints” of individual IBD patients. This “fingerprint” will allow for a personalized approach to treatment, directly targeting the aberrant pathways. Ultimately, through redefining IBD classification by the underlying molecular processes, Dr. Mulder hopes to improve IBD treatment success rates and improve patient outcomes.
