Dr. Graham's research has had an extensive program examining the impact of caffeine or coffee ingestion on carbohydrate metabolism and insulin sensitivity. However, now it is focused on muscle glycogen with a particular focus on the roles of regulatory proteins that are associtaed with the glycogen granules. This critical store of carbohydrate exists in highly organized granules in specific locations within the cell. There is a large group of proteins/enzymes that bind to the granule and are vital to the regulation. The nature of these actions are very likely to be key to carbohydrate regulation in not only exercise, but in health and disease states. Due to his retirement in 2013, Dr. Graham will not be accepting anymore students.
