AGL was born (1962) and bred in Taranaki, New Zealand and studied Chemical Engineering in NZ. Following graduation, worked for 3 years at an NZ food processing company doing general chemical engineering. In 1986, won a Prince of Wales Scholarship for PhD at Trinity College, University of Cambridge. Upon finishing PhD (awarded Danckwerts Prize for best PhD thesis), joined the Department of Chemical Engineering at Imperial College in 1990. Research into membrane separations, biotransformations, chemical and separations technology. Full Professor from 1999, published over 180 papers and granted 15 patents in chemical technology. Awards include Junior Moulton Medal (1993), Cremer and Warner Medal of IChemE (1997), and Silver Medal of Royal Academy of Engineering (2008). Leads a research group of 20 PhD students and Post-Docs, with current research interests in separations for chemical & pharmaceutical applications using solvent stable nanofiltration membranes. These membranes are able to separate at the molecular level, and remain stable in even very aggressive solvents. Elected a Fellow of the Royal Academy of Engineering in 2006, became Head of Department of Chemical Engineering at Imperial College in 2008.
In 1993, graduated with an MSc in Economics from London School of Economics (LSE) following part-time study. In 1996, founded Membrane Extraction Technology, a spin-out company which manufactures solvent stable nanofiltration membranes and carries out process development and commercialisation of membrane separation processes. On 1 March MET was acquired by Evonik Industries of Essen, Germany, and continues in business as Evonik MET Ltd.
