Dr. Li is a registered engineer in Ordre des ingénieurs du Québec (OIQ). He obtained a bachelor degree and a M.Sc.A. degree both in mining engineering in China, and a doctorate degree in France.

Dr. Li has been working in geotechnical engineering for many years. He passed about 4 years as post-doc and 7 years as Research Associate in geomechanics at Polytechnique Montréal. After then, he passed two years in Genivar (now WSP) as consulting engineer in geotechnics. From 2010 to 2012, he was an Associate Professor in geotechnics at École de technologie supérieure (ÉTS). Since 2012, he becomes Associate Professor in mining engineering at Polytechnique Montréal.

Dr Li is interested in several fields in geotechnical engineering (rock and soil mechanics). Since last ten years, he is particularly active in research on mine backfilled stopes for estimating the stresses in backfilled stopes and pressures on backfill barricades, sizing barricades made of waste rock, and assessing the required strength of cemented backfill with exposed faces.

Dr. Li was the Head of Mining Program from June 2020 to June 2023. Starting from May 2023, he serves the RIME at Polytechnique as the Scientific Director (
