James has a long record of commitment to academic endeavors, initially cultivated through his chemistry and biochemistry experiences at Connecticut College, and subsequent technology-driven basic science research during his gap year at Aerodyne Research, Inc. in Boston, MA. He has since transitioned his efforts to clinical outcomes research while completing his training at the University of Maryland. Outside of work, he finds passion in outdoor activities and his continued involvement in athletics after his collegiate track and field career, and spends much of his free time participating in multiple recreational soccer leagues in Baltimore. He is not only proud to be a resident of the University of Maryland Radiation Oncology team, but describes his experience with much gratitude.
