The field of diabetes research continues to grow at a rapid and exciting pace. The diabetes team at Johns Hopkins is committed to finding and developing methods to help people live a full and healthy life with diabetes. Over the past 20 years, we have conducted research in a number of important areas, including glucose monitoring, hemoglobin A1c, and diabetes technologies such as continuous glucose monitoring and implantable insulin pump therapy. All of these efforts are made possible with the help of volunteers, who by participating in these studies help us answer important questions about diabetes. Below is a list of the current research taking place at the Diabetes Center. If you would like to participate in one of our studies, please contact the research program coordinator listed for each study for more information.
