Carolyn Keever-Taylor, PhDCarolyn Keever-Taylor, PhD

Director, Blood and Marrow Transplantation Processing Laboratories


Dr. Carolyn Keever-Taylor has is a recognized expert in the field of Cellular Therapy with over 100 full length publications, including journal articles and book chapters. She is an active in a number of professional societies including the American Society for Hematology (ASH) the International Society for Cellular Therapy (ISCT) the American Society for Blood and Marrow Transplantation(ASBMT) and the World Wide Network for Blood and Marrow Transplantation (WBMT) where she has served on various committees, advisory boards, and executive boards.  Dr. Keever-Taylor has also participated actively in the Foundation for the Accreditation of Cellular Therapy (FACT) since its founding in 1996 to set standards, perform inspections, and provide education for inspectors and programs. She currently serves as the FACT Vice President.  She additionally serves on the steering committees of several multi-center clinical trials involving novel methods of cellular therapy product processing or use of such products for new indications.


Dr. Keever-Taylor's primary research interests have been focused on immune reconstitution after BMT and the use of immunotherapy to improve transplant outcomes. She has been a principle or co-investigator on several protocols conducted under investigational new drug (IND) approvals.  The most recent project uses cytotoxic T cell lines from transplant donors prepared in the laboratory to recognize common viral pathogens (EBV, CMV, Adenovirus) that cause considerable morbidity and mortality in BMT patients who have not yet recovered a fully functioning immune system.
