Piotr Smolarkiewicz received M.Sc. and Ph.D. degrees from the University of Warsaw, in geophysics and physical sciences in 1973 and 1980, respectively. In 1981, he went to Boulder, Colorado, to join as a post-doctoral fellow in the Advanced Study Program at the National Center for Atmospheric Research (NCAR). Since 1973, he has been an assistant professor at the Department of Physics, University of Warsaw. After the post-doctoral appointment, since 1983 he has been a scientist at NCAR, in the rank of Senior Scientist since 1994. In 2005-2006, he served as an NCAR Science Advisor, and since 2007 he has been the Head of the Computational Mathematics Group at the Institute for Mathematics Applied to Geosciences (IMAGe) of NCAR. In 2013 he joined the Research Department of the European Centre for Medium-Range Weather Forecasts (ECMWF) as a consultant. Piotr's research centres on computational fluid dynamics (CFD), with particular emphasis on all-scale geophysical circulations and basic fluid dynamic of rotating stratified flows. He is the principal developer of the multi-scale, multi-physics, high-performance research code EULAG built on high-resolution transport methods MPDATA, which he has originated and developed at NCAR. Piotr’s interests include scientific computing, geophysical flows of all scales, solar dynamo, physics of plasmas, non-Newtonian fluids, and dynamics of continuous media. His current activities at ECMWF focus on the development of an interdisciplinary forecasting system (PantaRhei) for simulating multi-scale fluid flows.
