Deyin Xing, M.D., Ph.D., joined our faculty as an assistant professor in the Division of Gynecologic Pathology in July 2016. Dr. Xing earned his medical degree in 1999 from Nankai University in Tianjin, China. Following medical school, he spent three years completing a doctoral degree in oncology, under the supervision of Dr. Dongxin Lin, at Peking Union Medical College in Beijing. In 2003, he joined the laboratory of Dr. Sandra Orsulic as a research fellow in the department of pathology at the Massachusetts General Hospital/Harvard Medical School where his research focused on the development of genetically engineered mouse models of ovarian cancer and of leiomyosarcoma. In 2007, Dr. Xing joined the laboratory of Nobel Prize Laureate Dr. Phillip Sharp at the David H. Koch Institute for Integrative Cancer Research at Massachusetts Institute of Technology where his translational research involved the delivery of siRNAs to silence genes in genetically defined murine ovarian tumor models.

Dr. Xing resumed his clinical career as an anatomic pathology resident in 2011 in the department of pathology at the University of Alabama at Birmingham. In 2014, he came to Hopkins for a gynecologic pathology fellowship training mentored by Dr. Robert Kurman, Dr. Biggy Ronnett and Dr. Russell Vang. Dr. Xing’s clinical and translational research centers on novel diagnostic and prognostic markers of gynecologic neoplasms and molecular alterations of these tumors. more
