Biographical Sketch 
Dr. Feng graduated from Medical College of Jinan University and received his PhD from Guangdong Cardiovascular Disease Research Institute in China. He pursued his postdoctoral research training in the Vascular Biology and Hypertension Program in UAB, under the supervision of Dr Oparil between 2002 and 2006. In 2008, Dr Feng joint Division of Nephrology as research associate. He was promoted to Instructor in 2012, and assistant professor in February 2016.

Research/Clinical Interest
The Role of Transcription Factor ETS-1 in Hypertensive Renal Damage and Vascular Disease
Dr Feng’s research interest has been focused on the role of transcription factor ETS-1 in the acute vascular injury response. The major achievements, published in 2010 in Hypertension, were the demonstration that ETS-1 is up-regulated in acute arterial injury, triggering a robust inflammatory response followed by vascular remodeling and neointima formation. He showed that blocking ETS-1 with a dominant negative peptide reduced the expression of inflammatory mediators and neointima formation in a rat model of acute carotid injury. In another project he demonstrated the role of ETS-1 in renal injury and inflammation induced by angiotensin II. In this study, Dr Feng demonstrated that blockade of ETS-1, not only decreased angiotensin II induced macrophage infiltration, but also reduced TGF-beta; and CTGF expression, reduced oxidative stress and improved renal function. These studies were also recently published in Hypertension 2012. Since 2012, we has focused his efforts on defining the role of the ETS-1 in the pathogenesis of the neointima formation in a mouse model of arteriovenous fistula (AVF). AVF dysfunction is extremely important complications of hemodialysis patients with end stage kidney failure. The long term goal of this study is development of novel therapeutic strategies for the treatment and prevention of AVF dysfunction.
