Dr. Liwen Xiao

Assistant Professor (Civil Struct & Env. Eng.)

Dr. Liwen Xiao received his PhD degree at NUI Galway and worked as a lecturer there before joining the Department of Civil, Structural and Environmental Engineering at TCD as Assistant Professor in 2013. Since joining TCD, Dr Xiao has continued his research work in the following areas: (1) sustainable treatment of wastewater, (2) emerging contaminants (microplastics, antibiotics) detection and removal and (3) impacts of human activities on water quality and ecology. He currently has 4 PhD students in his research group and is involved in a number of research projects funded by national and international funding agencies. Dr Xiao is a college tutor and a deputy director of the research centre TrinityHaus. He is the director of MSc in Engineering
