About Norm Robillard

Dr. Norm Robillard earned his Ph.D. in microbiology from the University of Massachusetts, Amherst, where he studied Bacillus anthracis and other Bacillus species. His post-doctoral research at Tufts University focused on antibiotic resistance and gene transfer between gut microbes, including Bacteroides fragilis and E. coli. Over the course of his career in the pharmaceutical and biotech industries, Dr. Robillard studied the genetics of antibiotic resistance, septic shock, viral illnesses, and both antimicrobial and antibody-based therapies. He later founded the Digestive Health Institute, where he developed the Fast Tract Diet—a science-based, root-cause approach to resolving functional gastrointestinal disorders, gut dysbiosis, other digestive and related health conditions. As the author of the Fast Tract Digestion book series and creator of the Fast Tract Diet mobile app, Dr. Robillard was the first to identify excess intestinal fermentation as a key driver of reflux. He also introduced the link between gas-producing gut bacteria, intragastric pressure, and nutritional malabsorption as a mechanism behind reflux symptoms. His latest work, the Fast Tract Digestion series, offers a safe, effective alternative to proton pump inhibitors (PPIs), H2 blockers, IBS medications, and antibiotics for conditions such as GERD, LPR, IBS, SIBO/IMO and related disorders.
