His educational training is in the areas of biomedical and mechanical engineering and applied mathematics. His lab is engaged in basic scientific research that uses fluid dynamics, solid mechanics, and intravital microscopy to study blood flow in the microcirculation and to elucidate mechanisms by which the lining of blood vessels can determine vascular health and disease. In addition to this research, he is also committed to creating and integrating technologies to build a bionic endocrine pancreas. His interest in a bionic pancreas is quite personal, and began when his fourteen-year-old son, David, developed type 1 diabetes before the age of one. His goal is to have the mathematical control algorithms that he developed with one of his postdoctoral fellows, Dr. Firas El-Khatib, hard at work closing the loop for his son and others with diabetes before David goes off to college.
