The primary goal of my research is to identify the physiologic mechanisms which regulate the function of microscopic blood vessels. One project area addresses the high incidence of kidney failure among diabetic patients. The research seeks to identify the role of insulin to regulate the constrictor function of kidney arterioles. The second focus area is the regulation of blood flow to bone. The research addresses important orthopaedic problems such as osteoporosis, delayed fracture healing and smoking-related orthopaedic complications by assessing changes in bone arteriolar function associated with aging and nicotine consumption.
