Xin Chen, Ph.D., is an Assistant Professor in the Department of Pediatrics at UT Southwestern Medical Center. He joined the UT Southwestern faculty in 2018 after being in the medical field for more than 20 years.
Dr. Chen earned his medical degree at North China Coal Medical College in 1986, followed by a master’s in pathophysiology in 1989 at Hengyang Medical College. In 2000, he completed his Doctor of Philosophy in Biosignal Pathophysiology at Kobe University in Kobe, Japan. He then completed a fellowship at Case Western Reserve University.
The recipient of multiple investigator awards for research, Dr. Chen focuses his scientific efforts on developing adeno-associated virus (AAV) based gene therapy treatments for neurological diseases with the goal of translating preclinical results into clinical trials.
