Qiuwen Wu
Professor of Radiation Oncology

My research interests include intensity-modulated radiation therapy (IMRT), volumetric modulated arc therapy (VMAT), electron arc therapy (EAT) and image-guided radiation therapy (IGRT). For IMRT, my work include the development of the research platform, fast and accurate dose calculations, optimization based on physical and biological objectives such as generalized equivalent uniform dose (gEUD), and delivery with dynamic multi-leaf collimator (DMLC). For VMAT, I am interested in the optimization, quality assurance and novel applications. For EAT, I'm interested in the treatment planning and delivery verifications. For IGRT, my work include development of the infrastructure of the online and offline image guidance, characterization of patient anatomic changes and treatment uncertainties, margin calculations, and adaptive treatment planning.

My clinical interests include prostate cancer, head and neck cancer, breast cancer and lung cancer.
