Preethi Srikanthan, MD, MS is an attending Endocrinologist and Professor of Medicine at the David Geffen School of Medicine at UCLA. She is the clinical director of research programs at the UCLA Research center at Alhambra where she oversees several large multicenter epidemiologic studies.

Dr. Srikanthan is an active investigator with Multiethnic Study of Atherosclerosis, a multicenter study evaluating modern risk factors impacting the progression from subclinical to clinical atherosclerosis. Further, her important work as a part of the Diabetes Prevention Program Outcome Study (DPPOS), has proven that even 10 years after a period of active lifestyle change or metformin use, these treatments can still delay type 2 diabetes and cardiovascular risk factors by as much as 34% in a group of obese Americans, at risk for diabetes. Further, Dr. Srikanthan's epidemiologic studies evaluating the metabolic and cardiovascular import of changes in body composition (specifically increased muscle mass) have lead to multiple highly cited manuscripts which have had significant public health impact.

Dr. Srikanthan's clinical interests include treating and preventing obesity and type 2 diabetes in addition to managing thyroid autoimmune disease/nodules and thyroid cancer.
