My research focuses on addressing the practical issues that industry faces when dealing with soils, or soil-like materials that do not have the typical characteristics of clean quartz sands, or plastic clays. I use advanced laboratory element testing, large scale testing, and constitutive and numerical modelling to address these problems.
My research group works on quantifying the response of non-classic geomaterials such as widely graded gravelly soils, low plasticity clays and silts. The work starts by characterizing the fundamental behaviour of different materials through element testing in our lab and continues by developing constitutive models, analyzing the problems and validating them through large scale tests. The results are being utilized to analyze field characterization tools such as the Cone Penetrometer, to demonstrate how the interpretation of these tests would be affected by different soil properties. Once the in-situ soil conditions are known, full scale problems, including documented case histories of performance under extreme events are analyzed to investigate the influence of material-specific behaviour on system performance.

Mason has eight years of experience working as a geotechnical engineer before joining the faculty at the University of Toronto. He has worked on a range of projects involving embankment dams, lifelines, bridges and mines for BC Hydro, California Department of Water Resources, Los Angeles Department of Water and Power, California Department of Transportation and Golder Associates. His areas of expertise are monotonic and cyclic response of soils, liquefaction assessment, sampling and laboratory testing of soils, field investigation and site characterization, instrumentation, dynamic testing of piles, and numerical modelling.
