Professor Simon Michael Papalexiou’s research is at the forefront of hydroclimatic variability and extremes, bridging advanced space–time stochastic modeling, downscaling, and climate change diagnostics.
At UNU-INWEH, he serves as the Hydroclimatic Diagnostics Lead, developing innovative tools to detect, attribute, and project shifts in extreme events and assess their impacts on critical systems. He also heads the Storms Module within the UNU Sustainability Nexus AID program.
Throughout his career, Prof. Papalexiou has pioneered stochastic modeling frameworks, most notably CoSMoS, a widely used open-source software suite with a global user base. He has authored nearly 100 peer-reviewed papers in acclaimed journals and delivered hundreds of presentations worldwide. He is currently Professor of Natural Hazards in the Department of Civil Engineering at the University of Calgary.
Prof. Papalexiou is Vice-President of the International Commission on Statistical Hydrology (ICSH-IAHS) and serves as Associate Editor for Water Resources Research (AGU) and the Journal of Hydrology (Elsevier). His contributions have earned him several honors, including the 2024 AGU Natural Hazards Early Career Award and multiple Best Paper Awards.
