Dr. Hawley received a B.S. in Chemical Physics from Queen’s University in Kingston, Ontario, Canada in 1979 and, after graduate studies at the Ontario Cancer Institute under the supervision of Dr. Nobumichi Hozumi, obtained his Ph.D. in Medical Biophysics from the University of Toronto in 1984. Following three years of postdoctoral training in developmental hematopoiesis with Dr. Beatrice Mintz at the Fox Chase Cancer Center in Philadelphia as a Fellow of the Medical Research Council of Canada, Dr. Hawley returned to Canada where he was a Career Scientist of the Ontario Cancer Treatment and Research Foundation, first at the Ottawa Cancer Center and subsequently in the Cancer Biology Division of the University of Toronto’s Sunnybrook Health Science Center. In January 1996, Dr. Hawley moved to the Toronto General Hospital where he was Scientific Director of the Oncology Gene Therapy Program and Head of the Oncology Research Laboratories. He held these positions and was an Associate Professor of Medical Biophysics and Medicine at the University of Toronto until January 1999, when he joined the Jerome H. Holland Laboratory for the Biomedical Sciences in Rockville, Maryland—the national research and development division of American Red Cross Biomedical Services—to lead the newly created Hematopoiesis Department. Dr. Hawley was appointed to the faculty of The George Washington University School of Medicine and Health Sciences as Professor of Anatomy and Cell Biology in December 1999 in accordance with an Affiliation Agreement between GW and the Red Cross. In January 2002, Dr. Hawley was named Executive Director of Cell Therapy Research and Development at the Red Cross, assuming leadership of the Holland Laboratory’s Blood and Cell Therapy Development Department while maintaining his position as Head of the Hematopoiesis Department.
