Ge Wang

Clark and Crossan Endowed Chair Professor, School of Engineering

Ge Wang’s Biography: Ge Wang is Clark & Crossan Endowed Chair Professor and Director of Biomedical Imaging Center, Rensselaer Polytechnic Institute, Troy, New York, USA. He published the first spiral/helical cone-beam/multi-slice CT algorithm in 1991 and has then systematically contributed many papers on this particular topic. Currently, there are 100+ million medical CT scans yearly with a majority in the spiral/helical cone-beam/multi-slice mode. Dr. Wang’s group and collaborators developed interior tomography theory and algorithms to solve the long-standing “interior problem” for high-fidelity local reconstruction, enabling omnitomography (“all-in-one” and “all at once”) with simultaneous CT-MRI as an example. He initiated the area of bioluminescence tomography with a significant impact on biophotonics. He has published 480+ journal publications, receiving a high number of citations and academic awards. His results were featured in Nature, Science, PNAS, and news media. In 2016, he published the first perspective on deep-learning-based tomographic imaging as a new direction of machine learning, and with his coauthors the first book on deep learning based tomography and the Nature Machine Intelligence paper on the superiority of deep learning over iterative reconstruction. His team has been continuously well-funded by federal agencies and leading companies, actively translating deep learning techniques into imaging products. His interests include medical imaging and machine learning. He is the Lead Guest Editor for five IEEE Transactions on Medical Imaging Special Issues, Founding Editor-in-Chief of International Journal of Biomedical Imaging, Board Member and Senior Editor of IEEE Access, and Outstanding Associate Editor of IEEE Trans. Medical Imaging, Medical Physics, and Machine Learning Science and Technology. He is Fellow of IEEE, SPIE, OSA, AIMBE, AAPM, AAAS, and NAI.
