Research focus

Our research goal is to study other medications as an adjunct therapy to insulin in Type 1 Diabetes to improve blood glucose control, weight loss, decrease the risk of diabetic ketoacidosis (DKA), and cardiovascular complications.

Jeremy Hodson Pettus MD, Associate Professor of Medicine
Division of Endocrinology, University of California San Diego 
Jeremy Pettus MD was diagnosed with type 1 diabetes (T1D) at the age of 15 and since that time has dedicated his career to helping and treating others diagnosed with T1D.  His research now spans all areas of type 1 research including immunotherapies to treat the underlying disease, novel therapies beyond insulin to help improve blood sugars and improve quality of life, and new technologies including artificial pancreas devices. Through this research, Dr. Pettus's group has become internationally recognized as pioneers in new T1D therapies. 
In addition to his time in research, Dr. Pettus also sees patients in the UCSD T1D clinic that specializes in state-of-the art care.  Finally, Dr. Pettus is a well-known educator and works with the not-for-profit organization "Taking Control of Your Diabetes" (TCOYD.org).  This organization creates free educational content for individuals living with type 1 and type 2 diabetes.  This content includes original diabetes-themed songs (which he writes and performs) and entertaining videos that frequently feature Dr. Pettus is some new wig or ridiculous costume.
Dr. Pettus is truly passionate about T1D care and research and is extremely proud of the group he has the privilege of working with every day.
