Zongwei Zhou obtained his PhD degree from Arizona State University (ASU) supervised by Dr. Jianming Liang. Zongwei holds a perfect GPA (4.0/4.0) and has received the University Graduate Fellowship twice from ASU. Drawing upon the realms of biomedical informatics, computer vision, and deep learning, his research focuses on developing novel methodologies to minimize the annotation efforts for computer-aided diagnosis and medical imaging. In addition to 11 U.S. patents pending, Zongwei has published 4 peer-reviewed clinical abstracts and over 10 peer-reviewed journal/conference articles, two of which have received the MICCAI Young Scientist Award and Elsevier-MedIA Best Paper Award. Two of his journal publications have been ranked among the most popular articles in IEEE TMI and the highest-cited article in EJNMMI Research, respectively. Furthermore, Zongwei has been awarded as the co-PI of the Bridges AI program from XSEDE. Zongwei also plays an active role in the leading societies of the computer vision and medical imaging field. He serves as a reviewer of IEEE TPAMI, MedIA, IEEE TMI, etc. and he was on the program committee for MICCAI in 2020, 2021; AAAI in 2020, 2021.
