Civil and Environmental Engineering

I am a Senior Lecturer 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 explore advanced experimental methods in the laboratory and at full-scale to resolve applied and fundamental research challenges in hydraulic engineering including air-water flow phenomena, optimisation of water engineering infrastructure for flow conveyance, fish passage and environmental flows. 
I have successfully supervised four PhD students to completion and supervise currently six further PhD students. I have a strong track record of publishing in high-ranking journals comprising more than 50 journal papers and more than 50 peer-reviewed conference papers. I have been a chief investigator in a number of fundamental and applied research grants totaling more than $5.2M. I am a the Vice Chair of the Leadership Team of the IAHR Hydraulic Structures Committee and the Deputy Chair of the Engineers Australia's Sydney Water Panel. I have been member of the organization and scientific committees of a number of national and international conferences including the IAHR World Congress and the Hydraulics in Water Engineering conferences of Engineers Australia.

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)

- Leadership team Member. IAHR Hydraulic Structures Committee (2017-present)

- Vice Chair. IAHR Hydraulic Structures Committee (2021-present)

- Secretary. IAHR Hydro-Environment Division (2018-2019)

- Committee Member. Engineers Australia Sydney Water Panel (2015-present)

- Deputy Chair. Engineers Australia Sydney Water Panel (2021-present)

- Local Organizing Committee member. 34th IAHR World Congress 2011, Brisbane.

- Chair of Scientific Committee and Member of Local Organizing Committee. 13th Conference on Hydraulics in Water Engineering, 2017, Sydney, AU.

- Co-Chair of Scientific Committee and member of Local Organizing Committee. 14th Conference on Hydraulics in Water Engineering, 2020, Auckland, NZ.

- Member of International Scientific Committees for 6th, 7th, 8th IAHR International Symposium on Hydraulic Structures as well as the 5th, 6th, 7th and 8th IAHR International Junior Researcher and Engineer Workshop on Hydraulic Structures.
