Huijun Xu

Huijun Xu, PhD, is an Associate Professor in the Department of Radiation Oncology at the University of Maryland School of Medicine, where she serves as the lead physicist for the University of Maryland Capital Region Medical Center. She holds certification from the American Board of Radiology in Therapeutic Radiologic Physics (2016).

Education

• 2008: B.S. in Applied Physics, Shanghai Jiao Tong University
• 2013: Ph.D. in Medical Physics, Virginia Commonwealth University
• 2015: Medical Physics Residency, University of Maryland

Research Focus

Dr. Xu's research centers on advancing precision in radiation therapy through computational methods. Key areas include:

• Probabilistic treatment planning for managing anatomical uncertainties (organ motion, delineation variations)
• Robust optimization frameworks for IMRT/VMAT
• Automation of quality assurance processes
• Dosimetry innovations for brachytherapy and electron therapy

Publication Trends

Her recent work (2014–2021) demonstrates a progression from foundational research on uncertainty management in prostate radiotherapy toward clinical implementation of automation tools. Key themes include robust optimization algorithms, system-specific treatment planning validation (e.g., RayStation, CyberKnife), and efficiency improvements for lung SBRT and electron therapy workflows.
