Cheng-Shie Wuu’s research focuses on clinical radiation dosimetry. He has been working on the verification of absorbed dose to the target volume for radiation therapy using 3-D gel and radiochromic dosimeter in conjunction with an optical CT scanner, electronic portal imaging device (EPID), as well as Cerenkov radiation. He has developed a fast optical CT scanner for the 3-D diosimeter readout. He has worked on the relative biological effectiveness (RBE) of various types of ionizing radiation in clinical use based on microdosimetric modelling.

Wuu’s main research interest is on the measurement and verification of 3-D dose distribution for complex radiotherapy techniques. He has used gel and radiochromic plastic phantom for radiation measurement. With optical CT scanning of the phantom and 3-D reconstruction software he has successfully demonstrated 3-D dose verification with high resolution and accuracy for advanced radiotherapy techniques. He has developed real-time monitoring of patient transit dosimetry using a commercial EPID. This technique was applied to patient treatment monitoring with an institutional review board (IRB) approved study. He is the Director of Medical Physics, Department of Radiation Oncology, at the Columbia University Medical Center and a Professor of Applied Physics in the School of Engineering and Applied Science at Columbia University. He is also the Co-Director of Medical Physics Graduate Program in the Applied Physics and Applied Mathematics Department. Wuu received a BS in physics from National Tsinghua University in Taiwan and a PhD in biophysics from the University of Kansas in 1985. He is a fellow of the American College of Radiology (ACR 2006), and a fellow of the American Association of Physicists in Medicine (AAPM 2007).
