Researcher biography

Dr Liu Ye is an Associate Professor at The University of Queensland in the School of Chemical Engineering. Her research focuses on sustainable and cost-effective water and wastewater treatment, including on-line process control, novel technology development, resource recovery and greenhouse gas (GHG) emissions (monitoring, modeling, and mitigation of N2O) from biological wastewater treatment processes. She has an established leadership in the research field of understanding and mitigating fugitive GHG emissions from urban wastewater systems.She has more than 120 publications, over 70 fully refereed journal papers (with over 3400 citation and an h-index of 32 (Google Scholar, June 08, 2021)), and is a co-inventor of four patents. A/Prof Ye has been awarded over $6M competitive research funding - including four Discovery Projects, Linkage projects, and the Discovery Early Career Researcher Award (DECRA) Fellowship from Australian Research Council - along with several other industry-funded projects. She has a broad research collaboration within academia and industry (e.g. Melbourne Water Corporation, South Australia Water Corporation, Western Water Corporation, Water Utilities, Icon Water etc) in the past 10 years. Liu’s research is having a substantive impact in gaining a deeper scientific understanding of the fundamental biological N2O production pathway during wastewater treatment. The research outcome not only offers a long-term cost-effective solution for water utilities to reduce emissions but also informs the development of new policy such as 2019 IPCC Guidelines for National and International Greenhouse Gas Inventories. Liu also received more than eight scientific awards (including Research Innovation Award from Australia Water Association, UQ Foundation Research Excellence Award, etc.), and the EAIT faculty teaching excellence award. She is an elected management committee member of the (IWA) Specialist Group on Instrumentation, Control, and Automation (ICA). She is also a member of the Australia Association for Engineering Education (AAEE) and Engineers Australia (EA).


Liu’s research includes greenhouse gas (GHG) emissions and mitigation from biological wastewater treatment processes; sludge minimization and biogas production enhancement by using free nitrous acid (FNA) based technology; advanced biological nutrient removal (BNR) technology development; on-line process control and optimisation and resource recovery from wastes.
