Professor Laurence Gill

Professor (Civil Struct & Env. Eng.)

Professor Laurence Gill is Chair of Environmental Engineering in the School of Engineering, Trinity College Dublin. His research interests involve studying the fate and transport of both air and water-borne pollutants in the natural and built environment, as well as the development of passive treatment processes. Much of the work involves extensive field studies which are then used to develop mathematical models to gain further insight into the processes. Prior to joining at Trinity College in 1999, he spent several years working in the UK water industry on the design of water and wastewater treatment processes for urban populations.
