Xiaolei Tang, MD, MSc, Ph.D

Associate Professor, Physiology and Immunology


Dr. Tang holds an MD degree from the Wannan Medical College, Wuhu, China; a Master's in Immunology from Shanghai Medical College Fudan University; and a Ph.D. in Microbiology and Immunology from the University of Arizona.

Following medical school, Dr. Tang practiced medicine as a radiologist for two years at Huangshan City People's Hospital, Huangshan, Anhui Province, China. He then received a Master's degree in immunology in the Department of Immunology at Shanghai Medical College, Fudan University, where he continued as a lecturer for four years following graduation. Afterward, Dr. Tang obtained his Ph.D. in microbiology and immunology at the University of Arizona. He was then trained as a postdoctoral fellow in Dr. Vipin Kumar's research laboratory at Torrey Pines Institute for Molecular Studies in San Diego, California, where he remained for four years. Subsequently, he accepted a Research Associate position in the laboratory of Dr. Harvey Cantor at the Dana-Farber Cancer Institute, Harvard Medical School, Boston, Massachusetts. After 3.5 years at Harvard, Dr. Tang was a faculty member at the University of Texas, El Paso, Texas, for three years. Later, he decided to move to the Division of Regenerative Medicine, Department of Medicine, School of Medicine at Loma Linda University in California, first as an Assistant Research Professor and then as an Associate Research Professor for a total of 6 years. Dr. Tang joined the Long Island University College of Veterinary Medicine in September 2019. 

Dr. Tang has considerable teaching experience. He has taught undergraduate and graduate students, medical students, and other professional students. He has developed syllabi and directed courses mainly in immunology. Dr. Tang often emphasizes essential basic science concepts in clinically relevant scenarios that students can easily understand with different levels of knowledge. Dr. Tang strives to convey his passion for discipline and promote a learning environment that fosters student participation and small group discussion during his interactions with students. 

Research Interests:

Dr. Tang's research interests include regulatory T (Treg) and adult stem cells. In Treg cells, his laboratory investigates strategies that harness immune cells ex vivo and in vivo to enhance Treg cell function, specifically in tissues with immune disorders.

In adult stem cells, Dr. Tang’s laboratory focuses on studying technologies that enhance the functions of adult stem cells to improve tissue repair. Currently, his lab is investigating the role of de novo synthesized locally high concentrations of the active vitamin D and retinoic acid in the functions of intestinal stem cells (ISCs).
