Biography

Richard Wan is a Professor of Civil Engineering with the University of Calgary. He received a Civil Engineering degree from École Nationale des Travaux Publics de l’État, France in 1983, an MSc in Geotechnical Engineering from the University of Ottawa in 1985, and a Ph. D in Geomechanics from the University of Alberta in 1990.  

His research is mainly focused on modern analytical, computational and experimental methods for studying the mechanical behaviour of geomaterials. This has involved theoretical work on the description of failure within contemporary approaches that exploit the theory of bifurcation and micromechanics so that various forms of ruptures and material instabilities can be explained coherently. On the other hand, he has also worked on more practical issues in the application of Geomechanics Principles and Computational Mechanics to solve energy resource extraction and geo-environmental problems in the oil industry. Another avenue of his research work is in Biomedical Engineering where he has applied basic Geotechnical Engineering knowledge of frost heave and clay swelling to both model prostate cryosurgery and study the cryopreservation of cartilage respectively. He currently has over 150 publications (refereed journals, conference proceedings and edited books), with a successful track record in research grants, as well as graduate student supervision. 

He is very much involved with the geomechanics society having organized and led several important technical meetings. He currently sits on the editorial board of several well known geotechnical engineering/geomechanics journals, technical committees, and has also served as a scientific reviewer for various international organizations including NSERC (Natural Sciences and Engineering Research Council of Canada), among others.  

He was the first recipient of the prestigious R.J Melosh medal in finite element modelling, Duke University, USA, and earned several research excellence accolades from his peers. As a distinguished visiting professor, he also collaborates with several renowned institutions in the UK, France, the Netherlands and Japan.
