Resume

Xiaochuan Pan received his B. S. in Physics from Beijing University, his M. S. in Physics fromthe Institute of Physics of Academia Sinica, his M. S. and Ph. D. in Physics from The University of

Chicago. He is currently a Professor in the Department of Radiology, Department of Radiation

and Cellular Oncology, the College, the Committee on Medical Physics, and the Cancer

Research Center at The University of Chicago. Dr. Pan's research interest centers on imaging

physics and mathematics, signal processing, image quality assessment, and their applications

to a wide range of medical imaging problems. Dr. Pan has authored and co-authored more

than 290 journal and proceedings papers and several U.S. patents. He has received numerous

awards, including the Early Achievement Award of IEEE NPSS and is a fellow of AIMBE, IEEE, OSA and SPIE. Dr. Pan is serving, and has served, as a member of the technical committees for and as a program, track, symposium, or session chair for a number of professional conferences. He is currently serving as an Associate Editor or an Editorial Member for several professional journals, including IEEE Transactions on Medical Imaging and IEEE Transactions on Biomedical Engineering.He is also a regular reviewer for a large number of journals in the field.
