He has 20 years’ experience in research and teaching. He is an executive committee member of IWA-India Chapter and represents South-Asia in IWA specialist group for METRAL and related substances. He has won several accolades including Best Research Award (2013) at 4th Asia Pacific Water Young Professional Conference, two Best Poster Awards (2013 and 2016), DST young scientist grant, JSPS Research Fellowship, COE Young Researcher Fund, and Linnaeus-Palme Grant from SIDA, Sweden. He is associate editor for Elsevier’s Journal of Groundwater for Sustainable Development and Japan Society for Water’s journal Hydrological Research Letters. He was the lead editor for four virtual special issues for international journals including Journal of Hazardous Material. Most recently, he has joined a global collaboration of 51 institutes on Wastewater-Based Epidemiology of COVID-19. Dr. An is an Associate Professor in the School of Energy and Environment at the City University of Hong Kong (CityU). She received her PhD in Civil and Environmental Engineering at the Hong Kong University of Science and Technology (HKUST). Her dissertation on sludge minimization mechanisms in Oxic-Settling-Anaerobic process in wastewater treatment system was well received and cited. Since 2009, Dr. An has extended her research and education career with Sustainability concepts at the University of Tokyo, Japan. She has conducted several research projects and field work focused on sustainable water management and urban development. Dr. An is a member of the Hong Kong Institution of Engineers (MHKIE), registered Korea civil engineer, member of the association of energy engineers (MAEE), certified carbon auditor professional (CAP), and member of the international water association (IWA). Her research emphasizes the development of emerging membrane technologies and innovative approaches to solving pressing water quality and quantity issues. Dr. Cetecioglu is Asscoiate Professor in the Department of Chemical Engineering-KTH, Sweden. Her research has centered on resource recovery from wastewater by combining wastewater engineering and molecular microbiology ecology. She applied her knowledge recently is carbon neutral wastewater treatment plants, which has attracted a huge amount of interest during recent years due to the potential of turning waste into resources and for the potential of securing a future supply of bio-based products. She is developing resource recovery units which are exchangeable in existing wastewater treatment plants in one of her ongoing projects, CarbonNextGen. This project has recently been listed in the top 100 projects by the Swedish Royal Academy of Engineering Sciences. There is still a lot of work required to develop environmentally and economically sustainable processes capable of closing the circular economy loop and turning waste into resources. She has contributed more than 80 publications to leading international peer‐reviewed journals, conference proceedings, and books. One of the books to which she contributed was awarded by Turkish Academy of Science and this book is still used as course material in universities. She is member of both IWA and ISME and she is the leader of Circular economy Cluster at KTH Water Center.
