Dr. Lal Samarasekera is an assistant lecturer at York University in the Lassonde School of Engineering. His primary interest at present is engineering education. Dr. Samarasekera has been interested in the use of technology in engineering education, including web-based teaching and learning. Sustainable development in Engineering Education is a new area of interest for Lal. Dr. Samarasekera’s area of specialization is in Geotechnical Engineering.

Lal did his Master’s degree at University of British Columbia specializing in the area of geomechanics and constitutive relations. For his doctoral degree at University of Alberta, Lal used numerical modelling to analyze the behaviour of tunnels and excavations. Following his graduate research, Dr. Samarasekera had worked as a researcher and instructor for over 20 years and then joined the industry. He has also been interested in unsaturated soils mechanics and influence of vegetation on slope stability.

Prior to joining York University this year, Dr. Samarasekera had worked as a consultant for SNC Lavlin and Golder Associates.
