Overview

Dr. Richey is currently a faculty member in the department of Physiology and Biophysics at Keck School of Medicine of USC and a member of the diabetes and obesity research groups. Dr. Richey conducts research examining the relationship between diabetes, obesity and hypertension.

She has received research grants from the National Institute of Digestive, Diabetes and Kidney Disorders; National Institute of Heart, Lung and Blood; American Heart Association and the American Diabetes Association. Her research has resulted in publications in peer-reviewed medical journals. She is the immediate past president of the Los Leadership Council of the American Diabetes Association; chairperson of the Los Angeles African American Diabetes Task Force; and a peer grant reviewer for the Western and National Affiliates of the American Heart Association.
