Hongwei Li received the Ph.D. degree in the field of parallel computing from the institute of Software, Chinese Academy of Sciences, in 2002. From 2002 to 2005, he was with the Institute of Software as an Assistant Professor. In 2005, he joined the Center for Integrated Petroleum Research, University of Bergen, Norway, as a Post-Doctoral Researcher for image processing and inverse problem computing. Since 2008, he has been with the Department of Mathematics, Capital Normal University, Beijing, as an Associate Professor and then full Professor. His research is highly application oriented. Algorithms and methods for image enhancement, segmentation, and artifacts reduction developed by him have been utilized by CT equipment manufactures for improving image qualities. He is also deeply involved with the CT reconstruction community, and part of his research interest has been directed to develop reconstruction algorithms for dealing with challenging CT applications, such as low-dose CT and limited-angle CT. Currently, his research is supported by the projects from Natural National Science Foundation of China (NSFC) with granted numbers 61971292 (PI), 61901127 (Co-PI) and 61871275 (Co-PI), and he is also grateful to Beijing Higher Institution Engineering Research Center of Testing and Imaging as well as Beijing Advanced Innovation Center for Imaging Theory and Technology for funding his research work.
