Biography

Dr. Keith Ngan obtained his B.Sc. in Physics and Chemistry from the University of British Columbia and his M.Sc. and Ph.D. in Physics from the University of Toronto. Subsequently he was a postdoctoral fellow at the University of Chicago and a research associate at McGill University. In 2008 he moved to the UK Met Office, where he worked as a senior research scientist in the numerical weather prediction division. In 2013 he joined City University of Hong Kong as an Assistant Professor in the School of Energy and Environment.

Dr. Ngan's research seeks to improve understanding of basic dynamical processes in the atmosphere through high-resolution numerical modelling. He is especially interested in interdisciplinary research, more specifically the application of techniques and approaches from applied mathematics and fluid dynamics to practical atmospheric problems. His main areas of expertise are turbulence, data assimilation, atmospheric modelling and scalar mixing and dispersion. The current focus of his research is urban boundary-layer meteorology.
