Dr. Xu currently Professor of Nuclear and Biomedical Engineering at Rensselaer (Troy, New York). He is also the director for Center for Engineering-Based Patient Modeling (http://cepm.rpi.edu). In addition, he holds adjunct faculty appointments in Medical Physics at Albany Medical College (Albany, New York). He is also a visiting guest professor of Biomedical Engineering at Tsinghua University (Beijing, China) and at Huazhong University of Science and Technology (Wuhan, China).
Dr. Xu's research and teaching have centered on the understanding of scientific principles and development of biomedical applications related to delivery, measurement, and dosimetry of ionizing radiation. His most recent work involved one of the world's finest whole-body dosimetry models, VIP-Man, developed from the famous Visible Human Project and several most widely used Monte Carlo simulation codes. This model allowed radiation dose to human to be more accurately studied for the purposes of radiation protection and therapy.
