Hubert Chanson is Professor of Civil Engineering at the University of Queensland, where he has been since 1990, having previously enjoyed an industrial career for six years. His main field of expertise is environmental fluid mechanics and hydraulic engineering, both in terms of theoretical fundamentals, physical and numerical modelling. He leads a group of 5-10 researchers, largely targeting flows around hydraulic structures, two-phase (gas-liquid and solid-liquid) free-surface flows, turbulence in steady and unsteady open channel flows, using computation, lab-scale experiments, field work and analysis. He has published over 1,100 peer reviewed publications including more than 20 books. He serves on the editorial boards of International Journal of Multiphase Flow, Flow Measurement and Instrumentation and Environmental Fluid Mechanics, the latter of which he is currently a senior Editor. http: //www.uq.edu.au/ e2hchansDr Xinqian (Sophia) Leng is a postdoctoral research fellow at the University of Queensland. Her research interests include experimental investigations of unsteady rapidly-varied open channel flows, computational fluid dynamics (CFD) modelling of bores and hydraulic structures, and field investigations of tidal bores. She authored 45 peer-reviewed papers, including 20 international scientific journal articles. Dr Leng is the recipient of the 2018 Baker Medal, Institution of Civil Engineers, UK for the paper in the journal Engineering and Computational Mechanics, Proceedings of the Institution of Civil Engineers, UK. She was awarded a 2019-2021 Idex international research fellowship from the University of Bordeaux (France). Xinqian is actively involved in international collaborations with overseas research institutions such as the University of Bordeaux and Zhejiang Institution of Hydraulics and Estuary (China), as well as inter-disciplinary cooperation with industrial partners e.g. the New South Wales Department of Primary Industries Fisheries (Australia) and Queensland Department of Transport and Main Roads (Australia).
