Xin Li is an Assistant Professor of Medicine at Tufts Medical Center. Dr. Li received her B.S. in Microbiology from Fudan University in China and her PhD in Molecular and Cell Biology from the University of Maryland School of Medicine where she completed her PhD dissertation under the guidance of Dr. Harry Mobley. It is during her postdoctoral training in the laboratory of Dr. Erol Fikrig at Yale University School of Medicine when Dr. Li entered the field of Lyme Disease research, which has remained an investigative focus of her current laboratory. Prior to joining Tufts Medical Center, Dr. Li was an Instructor in Medicine at Harvard Medical School and then an Assistant Professor at the Ohio State University.
