BIOGRAPHY

Ir. Dr. Adeline Chua Seak May is a Professor at the Department of Chemical Engineering, University of Malaya. A PhD graduate from The University of Tokyo, Japan, she specialises in biological nutrients removal and resource recovery. She has published more than 40 papers in ISI-indexed journals and has supervised over 15 PhD and master students. Adeline is also a Chartered Engineer of IChemE, UK and a Professional Engineer of BEM, Malaysia. She works closely with the local wastewater treatment operators to improve the energy efficiency and performance of the wastewater treatment plants. The academia-industry research collaboration has earned her the award of international funding Newton Fund Impact Scheme. Her international research partners include NIES, Yokohama National University (Japan), SCELSE (Singapore), Kasetsart University (Thailand), and Newcastle University (UK). Adeline was also a visiting research fellow at The University of Tokyo (2012) and Newcastle University (2016-2019).

Her current research interests are related to the development of sustainable wastewater treatment process in the tropical climates, microbial ecology in tropical wastewater treatment plants, and resource recovery (biopolymer, biochemicals, biofuel and nutrients) from agro-industrial waste(water) streams.
