About
Xuejun Gu is a medical physicist and biomedical engineer whose research sits at the intersection of radiation oncology, robotic systems, and advanced imaging technologies. His most impactful contributions lie in stereotactic partial breast irradiation (S-PBI), where he has played a central role in pioneering single-fraction and 5-fraction treatment approaches for early-stage breast cancer through prospective multicenter phase 1 dose-escalation trials, work that has collectively garnered over 40 citations and helped establish new standards for minimally invasive, highly precise radiotherapy. Complementing this clinical focus, Gu has made notable strides in intelligent patient positioning, developing soft robotic and neuro-adaptive systems for maskless head-and-neck cancer radiotherapy — a technically demanding challenge where positioning errors can critically compromise treatment outcomes. His vision-based control frameworks and sensor-fusion methodologies represent meaningful advances in real-time, adaptive radiotherapy delivery. Gu has also contributed to quality assurance on robotic arm linear accelerators and explored ultrasound tomography guidance for breast irradiation, demonstrating a consistently innovative approach to improving treatment accuracy. With expertise spanning pediatric brain tumor radiotherapy and camera calibration algorithms, Gu's interdisciplinary body of work reflects a sustained commitment to translating engineering innovation into safer, more precise cancer care.
