Victor O.K. Li was born and raised in Hong Kong. He joined the University of Southern California (USC), Los Angeles, California, USA in February 1981, and became Professor of Electrical Engineering and Director of the USC Communication Sciences Institute.  Since September 1997 he has been with the University of Hong Kong (HKU), Hong Kong, where he is Chair of Information Engineering, and Cheng Yu-Tung Professor in Sustainable Development. He served as Head of the Department of Electrical and Electronic Engineering from 2012 to 2018,  and Assoc. Dean of Engineering at HKU from 2007 to 2012. He was the first Managing Director of Versitech Ltd. (http://www.versitech.hku.hk/), the technology transfer and commercial arm of HKU, and is now serving on the board of Sunevison Holdings Ltd, listed on the Hong Kong Stock Exchange. He served as the Convenor of the Strategic Research Theme of Information Technology at HKU, and as Co-Director of the Area of Excellence in Information Technology funded by the Hong Kong government.  He is the Chair of the Executive Committee, HKU Initiative on Clean Energy and Environment, an interdisciplinary research project with researchers from Engineering, Science, Architecture, and Social Science.  With colleague Dr. Jacqueline CK Lam, he established the HKU-Cambridge Clean Energy and Environment Research Platform, and the HKU-Cambridge AI to Advance Well-being and Society Research Platform.  The research focus is the development of AI technologies to solve important societal problems, or AI for Social Good. In Jan 2018, the team co-led by Dr. Jacqueline CK Lam and Prof. Victor OK Li was awarded a USD 6.3M RGC Theme-based Research Project to develop deep learning techniques for personalized and smart air pollution monitoring and health management.  More recently, the team was awarded the 2021 US National Academy of Medicine Healthy Longevity Catalyst Award. The co-author of seven US patents licensed for commercial exploitation, he is very active in technology transfer.  He is the Chairman of the Board and Co-Founder, with his PhD student Dr. Miles Wen, of Fano Labs (www.fano.ai), an award-winning AI Automatic Speech Recognition and Natural Language Processing Company. Sought by government, industry, and academic organizations, he has lectured and consulted extensively around the world.  Prof. Li chaired the Computer Communications Technical Committee of the IEEE Communications Society 1987-1989, and the Los Angeles Chapter of the IEEE Information Theory Group 1983-1985.  He co-founded the International Conference on Computer Communications and Networks (IC3N), and chaired its Steering Committee 1992-1997. He also chaired various international workshops and conferences, including IEEE INFOCOM 2004 and IEEE PIMRC 2015. Prof. Li served as an editor of IEEE Network, IEEE JSAC Wireless Communications Series, ACM/Springer Wireless Networks, IEEE Communications Surveys and Tutorials, Telecommunication Systems, and Springer Networking Science.  He also guest edited special issues of Elsevier Environmental Science and Policy, IEEE JSAC, Computer Networks and ISDN Systems, and KICS/IEEE Journal of Communications and Networking.  Prof. Li has been appointed to the Central Policy Unit and to the Hong Kong Information Infrastructure Advisory Committee by the Chief Executive of the Hong Kong Special Administrative Region (HKSAR).  He has also served on various other HKSAR advisory committees, including the Innovation and Technology Fund (Electronics) Vetting Committee, the Small Entrepreneur Research Assistance Programme Committee, the Engineering Panel of the Research Grants Council, and the Task Force for the Hong Kong Academic and Research Network (HARNET) Development Fund of the University Grants Committee.  He was a Visiting Professor at the Department of Computer Science and Technology, The University of Cambridge, Distinguished Lecturer at the University of Texas at Dallas, at the University of California at San Diego, at the University of London, at the National Science Council of Taiwan, and at the California Polytechnic Institute. Prof. Li has also delivered keynote speeches at many international conferences. He has received numerous awards, including the PRC Ministry of Education Changjiang Chair Professorship at Tsinghua University, the UK Royal Academy of Engineering Senior Visiting Fellowship in Communications, the Outstanding Researcher Award of HKU, the Outstanding Research Student Supervisor Award of HKU, the Croucher Foundation Senior Research Fellowship, and the Bronze Bauhinia Star, Government of HKSAR, China.  He is a Fellow of the Hong Kong Academy of Engineering Sciences, the IEEE, the HKIE, and the IAE.
