Simon Michael Papalexiou is an Assistant Professor of Statistical Hydrology and Stochastic Processes at the University of Saskatchewan and affiliated with the Global Institute of Water Security, Canada. His research focuses in advanced stochastic models, downscaling schemes, climate change diagnostics in hydroclimatology, and performing global analyses on hydroclimatic extremes. He has more than 20 papers published in the top journals of his field and more than 80 conference publications. Simon is Associate Editor in Water Resources Research (top journal in the field), has managed as Guest Editor a special issue on hydroclimatic extremes in Advances in Water Resources, and actively serves as reviewer in more than 25 journals. He has administered more than 10 conference sessions, including one of the most popular at the EGU General Assembly (2015-2017), has organized and been invited to give workshops on timeseries modeling and extreme events. He has served as Vice-president of the International Commission on Statistical Hydrology (ICSH-IAHS) and is currently the representative for USask to the Consortium of Universities for the Advancement of Hydrologic Science (CHUHSI). Simon conceived and leads the development of the CoSMoS R-package which is an innovative time series generation software in R with more than 5000 downloads within a year. His research has appeared in more than 100 news sites, mentioned in radio/tv news, and recognized as Editor’s choice in Science Magazine (2018), Editor’s highlight in Earth’s Future (2018) and AGU Eos Research Spotlight (2019).
