Associate Professor in the School of Civil and Environmental Engineering
I am an Associate Professor in hydraulic engineering and applied fluid mechanics in the School of Civil and Environmental Engineering. I hold a Dipl.-Ing. from RWTH Aachen University, Germany and a PhD in Hydraulic Engineering from the University of Queensland. I joined UNSW in 2014 and established the hydraulic engineering research group at the UNSW Water Research Laboratory. I am an expert in hydraulic engineering and applied fluid mechanics with internationally recognised research in air-water flows, hydraulic structures engineering and fish passage. I have pioneered the use of remote sensing technology for flow observations in hydraulic structures and, together with myÌý international collaborators, have made important changes to the way we measure and interpret air-water flows in the laboratory as well as in prototype structures.
I am the primary UNSW School of Civil and Environmental Engineering academic in hydraulic engineering and fluid mechanics, enabling me to transfer my passion for hydraulic engineering to the next generation of water engineers. Using my leadership positions in relevant committees of the International Association for Hydro-Environment Engineering and Research (IAHR) and Engineers Australia, I actively pursue changing the profession’s traditions towards the sustainable development goals.

I am leading the hydraulics research group and the cross-faculty Tube Fishway research collaboration at the Water Research Laboratory (WRL). Since joining WRL in 2014, I have continuously increased the research output and profile of the hydraulic research activities at WRL. I have been leading the development of advanced air-water flow instrumentation which is now used at several laboratories around the world. I have also pioneered the use of LIDAR technology in air-water flows in hydraulic engineering applications improving the design methods for physical modelling of water infrastructure and enabling remote sensing of air-water flows in field-scale settings. Using my air-water phase-detection intrusive probes, I have established research collaborations with researchers at several leading hydraulic engineering laboratories including ETH Zurich and the Utah Water Research Laboratory. Recently these air-water probes have been successfully employed in a prototype tunnel chute providing unique high-velocity data for the validation of scale effects. I am also leading the UNSW tube fishway project to enable fish migration across low to high head barriers.
I am engaged in a number if activities both at School level (Chair of the Research Management Group at WRL, Deputy Chair of the School's Technical Service Committee) as well as in a number of professional organisations including:
- Member of Engineers Australia (MIEAust)
- Member of International Association for Hydro-Environment Engineering and Research (IAHR)
