Junwei Du is a scientist at the Department of Biomedical Engineering, University of California at Davis (UC Davis). He obtained his B.S. degree in Applied Physics (2005) and Ph.D. degree in Electronic Science and Technology (2010) from the University of Science and Technology of China. His research focuses on developing high-resolution and high-sensitivity Positron Emission Tomography (H2RS-PET) for biomedical imaging. Dr. Du has published over 50 peer-reviewed research papers in the biomedical imaging field that cover detectors, electronics, system of PET.Krzysztof (Kris) Iniewski is managing R&D development activities at Redlen Technologies Inc., a detector company based in British Columbia, Canada. During his 15 years at Redlen he has managed the development of highly integrated CZT detector products in medical imaging and security applications. Prior to Redlen Kris hold various management and academic positions at PMC-Sierra, University of Alberta, SFU, UBC and University of Toronto. Dr. Iniewski has published over 150+ research papers in international journals and conferences. He holds 20+ international patents granted in USA, Canada, France, Germany, and Japan. He wrote and edited several books for Wiley, Cambridge University Press, Mc-Graw Hill, CRC Press, and Springer. He is a frequently invited speaker and has consulted for multiple organizations internationally.
