Steefan is a PhD candidate at Climate Change Research Center and ARC Centre of Excellence for Climate System Science, UNSW Sydney. He is interested in answering consequential research questions by applying novel statistical and computational analysis techniques to large geophysical datasets. His current research, for example, answers the question: How has rainfall changed across global land areas? Steefan’s approach involves investigating the changes in the entire distribution of precipitation alongside changes in the frequency. To facilitate this analysis, Steefan has also created a new global land-based gridded dataset of daily precipitation observations from 1950 to 2013 in collaboration with centre researchers A/Prof Lisa Alexander and Dr Markus Donat, The National Oceanic and Atmospheric Administration (US) and Deutscher Wetterdienst (Germany).
