Xiao Chen, MD, PhD
Assistant Professor of Medicine
Dr. Xiao Chen is Assistant Professor of Medicine at the Medical College of Wisconsin (MCW), Division of Hematology and Oncology. He obtained his medical degree from Fujian Medical University in China and his PhD degree in immunology from Technical University of Dresden in Germany. Dr. Chen came to the United States in 2001 and worked as a post-doctoral research fellow in the Department of Pediatric Surgery at MCW and was promoted to Research Scientist in 2004. He worked in the bone marrow transplantation program at MCW as a research scientist for several years, prior to joining the faculty in the Department of Medicine in 2010.
Dr. Chen's current research focuses on graft-versus-host disease (GVHD), which is a serious, frequently fatal complication following allogeneic hematopoietic stem cell transplantation. Specifically, he is investigating the role of retinoic acid in the pathophysiology of GVHD. This project is supported by prestigious Amy Strelzer Manasevit Research Award from the National Marrow Donor Program (NMDP). He also has a strong interest in tumor immunology and immunotherapy. His long term research goal is to find ways to augment the beneficial graft-versus-tumor (GVT) effect while minimizing GVHD in order to make allogeneic hematopoietic stem cell transplantation a more effective and safer treatment option for cancer patients.
