Short Description

Dr Wei Liu is currently an Associate Professor and Associate Head, and Presidential Young Scholar at the Department of Aeronautical and Aviation Engineering, The Hong Kong Polytechnic University. Prior to this, Dr Liu was a faculty member at UNSW Sydney in Australia and University of Glasgow in the UK, and was a Researcher at Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland. Dr Liu received his PhD in Transportation from the Hong Kong University of Science and Technology in 2014, and his BEng in Civil Engineering and Bachelor of Laws both from Tsinghua University in 2010. Dr Liu is a recipient of the Discovery Early Career Researcher Award from the Australian Research Council. His research group mainly works in data-driven decision analytics; large-scale transport system modeling, optimization and computing; aviation and rail system modeling; transport and aviation economics. Dr Liu’s research has been funded by Research Grants Council of Hong Kong, Australian Research Council, National Natural Science Foundation of China. His research mainly appears in leading international journals in the field such as Transportation Research Series (Part A/B/C/D/E) and Transportation Science. Dr Liu was the awardee of The European Transport Innovation Challenge 2017 under European Commission, and received a Best Paper Award from the International Transportation Economics Association (ITEA) for young scholars in 2015.
