Pampee P. Young is an Associate Professor in the Department of Pathology, Microbiology and Immunology at Vanderbilt University Medical Center. She serves as the Medical Director of Transfusion Medicine and Stem Cell Laboratory.  She completed her undergraduate at Rice University in Houston, Tx and obtained her M.D/Ph.D. degrees at UT Southwestern in Dallas, Tx.  She completed residency and fellowship training at Washington University Medical School in St. Louis.  There she began her studies in adult stem cell biology.  Her basic science research program in regenerative medicine addresses the role of stem cells and our endogenous repair mechanisms to drive wound healing.  An important long term goal of the laboratory is to translate our findings to help wounded military serviceman.  Our work is funded by the Veterans Affairs, pharmaceuticals and NIH.
