Dr. Xu received his Doctor of Medicine degree from Peking Union Medical College and his Ph.D. degree in Biomedical Sciences from the University of California, San Diego (UCSD). From 2005 to 2008, Dr. Xu was a postdoctoral fellow in Dr. Fred Gage’s laboratory at the Salk Institute, studying alternative splicing regulation in human and murine neural stem cells.
From 2008 to 2012, he completed the training in the Anatomic and Clinical Pathology at UCSD Medical Center. During 2011-2012, Dr. Xu has served as the Chief Resident in Pathology. During 2012-2013, Dr. Xu completed a fellowship in Hematopathology at Washington University in St. Louis.
In July 2013, Dr. Xu joined the faculty at VA San Diego Healthcare System and was appointed as Health Sciences Assistant Professor of Pathology at UCSD. Since then, he has served as the Pathology Site Director for Medical Education at VA San Diego. His clinical responsibilities include hematopathology, surgical pathology, flow cytometry and medical directorship of clinical laboratories.
Dr. Xu has received many honors and awards, including: American Heart Association Research Fellowship; Neurosurgery Neuroscience Consortium Fellowship; the Sidney Saltzstein Award for Patient Care; the David J. Epstein Award for Research Excellence; the Whitehill Prize for excellence in clinical teaching.
