Alexandre Langlois

Alexandre Langlois is a Professor at the University of Sherbrooke specializing in Arctic cryospheric research. His work bridges geomatics, hydrology, and climate science with a focus on winter extreme events and remote sensing applications.

His research interests center on Arctic snow and ice processes, particularly rain-on-snow events, extreme precipitation, and the development of remote sensing methods for quantifying surface changes in snow, sea ice, and glacier mass balance. Key areas include passive microwave radiometry, radar applications, UAV-based snow monitoring, and avalanche risk assessment.

Langlois' recent publications demonstrate strong trends in Arctic climate monitoring, with emphasis on microwave remote sensing techniques for snow water equivalent retrieval, freeze-thaw cycle detection, and climate change impacts on northern ecosystems. His work frequently integrates field measurements with satellite observations and numerical modeling.

Langlois has secured substantial funding as Principal Applicant for projects including NSERC Discovery grants on Arctic winter extreme events ($225,000), CFI Innovation Fund for Arctic climate monitoring ($4.26M), and multiple FRQNT and NSS contracts for avalanche hazard assessment. His research directly supports Indigenous knowledge integration for caribou habitat conservation and operational avalanche forecasting systems.

He leads the MOACC (Multidisciplinary Observatory for Arctic Climate Change) initiative and collaborates internationally with UK, Sweden, USA, and France on polar research. His lab develops specialized instrumentation including portable FMCW radars for snow stratigraphy analysis and UAV-based snow depth mapping systems.
