Dr. Rayhan Lal has lived with type 1 diabetes for several decades and studied electrical engineering and computer science at U.C. Berkeley. During his work in engineering his two younger sisters developed T1D and he decided to become an adult and pediatric endocrinologist. As an engineer and physician-scientist with diabetes, his primary research interest is the design, development and testing of new diabetes technology with his mentor, Dr. Bruce Buckingham. Rayhan collaborates with members of the Stanford Diabetes Research Center, industry, and open-source diabetes community to bypass the biological, technological, and human factor limitations of existing devices.
