About
Dr Liu’s research covers a wide range of topics from microbial fermentation, pyrolysis and gasification of organic wastes to wastewater treatment and resource recovery. She has undertaken many projects sponsored by the Singapore National Environment Agency, the Singapore Environment and Water Industry Programme, the Royal Society, the Royal Academy of Engineering, and BBSRC. She also conducted projects from the industry for technology demonstration and scaling-up.
Dr. Liu has published over 80 peer-reviewed journal papers with an H-index of 32 and over 3800 citations (Google Scholar). She is the author of three book chapters titled “Aerobic treatment of organic compounds in wastewater”, “Biological phosphoru removal processes”, and “Combusion, pyrolysis and gasification of sewage sludge for energy recovery”. Dr. Liu is an editorial board member/associate editor for journals Processes and Frontier in Energy Research, respectively, meanwhile, she is a technical reviewer serving for a number of international journals for years. Dr. Liu is also an active reviewer of research proposals for BBSRC, EPSRC, Royal Academy of Engineering, Royal Society and research councils in Canada, Finland, Switzerland, Croatia etc.
Dr Liu has an established and growing international reputation evidenced by being listed by Standford University as the top 2% of the world's leading scientists in recent consecutive years, i.e., 2022, 2021 and 2020.
