Director, Graduate Program in Biomedical Sciences
Associate Professor of Physiology and Pharmacology



Department of Bio-Medical Sciences

Dr. Chen is highly committed in using her medical knowledge and clinical/research experience to educate PCOM students. Since 2008, she has taught in pharmacology courses for the DO and biomedical sciences programs at PCOM, and since 2013 she has given biochemistry lectures to biomedical sciences students. Her teaching philosophy is student-centered and aims to provide students with accurate knowledge while nurturing them to develop critical thinking skills. She favors classroom dynamics that permit dialogue and foster student input, and she uses standardized practice questions in lecture to develop student problem-solving skills and to receive instantaneous feedback. Teaching also provides her the excellent opportunity to communicate with medical and graduate students, and to foster research work directed at meeting clinical needs. Additionally, she takes advantage of faculty strategic training lectures provided by PCOM to improve teaching skills by adapting to modern medical educational needs.

Dr. Chen has served as thesis advisor or committee member for several biomedical sciences master's students, and she also provides research training to DO and graduate work-study students in the lab. Moreover, she has established research collaborations with internal and external senior researchers, such as Dr. Greene, Dr. Barsotti, Dr. Young, and Dr. Hatcher at PCOM, and Dr. Weis at Texas Tech University. The collaborations have led to journal paper publications, abstract/poster presentations at national scientific meetings, and grant submissions.

For the past decade, Dr. Chen's research has been conducted in topics related to the cardiovascular system. Currently, she is interested in finding the key mechanisms involved in various cardiovascular diseases, such as myocardial infarction, stroke and diabetes. Vascular endothelial dysfunction and inflammation are two critical events initiating the pathogenesis of these diseases, and in her lab multiple animal models and biochemical techniques are combined to evaluate blood vessel biochemical properties (e.g., blood nitric oxide and hydrogen peroxide) in real-time, organ blood perfusion, and inflammation (i.e., leukocyte-endothelial interactions). Her research will clarify the roles of endothelial nitric oxide synthase, NADPH oxidase, damaged mitochondria, and key enzyme regulations and signaling pathways, which will provide new treatment strategies for cardiovascular diseases.
