Lecturer

I am a lecturer at the School of Engineering and Information Technology (SEIT), UNSW Canberra. Prior to this, I was working at the University of Queensland and the University of Stuttgart. My background is in Environmental Engineering and I am interested in open-channel hydrodynamics, including multiphase flows, hydraulic structures and measurement instrumentation.

Scholarships of $35,000 (AUD) are available for PhD students who achieved High Distinction (H1) in their undergraduate program and/or have completed a Masters by Research.

If you are interested in working on the topics listed under My Research (or closely related areas), please perform a self-assessment (https://selfassessment.research.unsw.edu.au/) and send me your me your CV, academic transcripts and a research proposal consisting of motivation, (brief) literature review, research objectives and proposed methodology.
