Xizeng Wu, Ph.D., DABR

Retired Professor Emeritus, Division of Physics and Engineering

Xizeng Wu, received his Ph. D. in theoretical high-energy physics in 1983 from City University of New York, and had his two-year postdoctoral training at Massachusetts Institute in 1983-1985, and another postdoctoral training at University of Cincinnati in 1985-1988. He received his medical physics fellowship training here at UAB in 1988, and he joined the faculty of the department in 1989.

Dr. Wu has a broad background and experiences in medical imaging physics. The mammography radiation dosimetry tables developed by him and colleagues have been adopted as the standard dosimetry tables in the U.S. since 1994. These dosimetry tables are used by medical physicists of this country in their routine works for the regulation compliance and mammography techniques optimization. In recent years his research focuses on the x-ray phase sensitive imaging, an emerging imaging field that attracts extensive research efforts over the world. He serves as the principal investigator or co-investigator for several federal grants to develop phase contrast imaging techniques. His works in this research field are widely cited. Dr. Wu participated in radiology resident teaching through several CT physics courses every year until his retirement in 2020.
