Glyn Williams-Jones


Dr. Glyn Williams-Jones completed a B.Sc. Hons (1993) and M.Sc. (1997) in geology at the Université de Montreal. He followed this with a Ph.D. (2001) at the Open University (UK) in Volcanology and postdoc at University of Hawaii at Manoa (2003). He started as an Assistant Professor at the Department of Earth Sciences, SFU in 2003, became Associate Professor in 2009 and Full Professor in 2017. Glyn is also co-Director of the Centre for Natural Hazards Research at Simon Fraser University. Since 2012, he has also acted as Volcanic Situations Duty Officer, for the Canadian Hazards Information Service, Natural Resources Canada.

Glyn is a physical volcanologist whose multidisciplinary research involves geochemical and geophysical modelling in conjunction with remote sensing to investigate the processes responsible for triggering volcanic eruptions as well those controlling persistently active volcanism. The principal focus of this research is the investigation of the interaction between the intruding magma and that already residing in the reservoir along with their precursory signals.
