Research

Our team's current research involves demonstrating the feasibility of onsite measurement of calprotectin by a Smart Sampling Toilet. Funded through an NIH Phase I Small Business Technology Transfer grant to Coprata, Inc., from the National Institute of Diabetes and Digestive and Kidney Diseases, the research is being done in collaboration with Dr. Amy Barto at the Duke University Gastroenterology IBD Clinic. Together, we seek to advance the development of a Smart Toilet with artificial intelligence that will enable remote monitoring of gastrointestinal illnesses such as Inflammatory Bowel Disease.
