Academic Career - an overview

Prof. Józef Spałek is Professor of Physics in Department of Condensed Matter Theory and Nanophysics in the Institute of Theoretical Physics of the Jagiellonian University, in Kraków. His postdoctoral work was carried out in England (at Imperial College of Science, Technology, and Medicine), in USA (at Purdue University), and in France (CNRS, Université Paris-Sud, and Université Paris-Nord). He was also a visiting professor at Purdue University (1988-1990), visiting scholar at Harvard University (1995-1996), and professor at Warsaw University (1991-1998). His research interests are concentrated on quantum materials with strongly correlated electrons and in particular, on theory of high temperature ad heavy-fermion superconductivity. He is also interested in nanophysics. In both topics he an original theoretical approach taking into account the strong correlations among the electrons. Recently, he has become interested also in the subject of emergent phenomena in Nature and related philosophical questions. He published over 280 scientific papers and a number of chapters in specialized monographs.

For his work he was awarded the Maria Skłodowska-Curie Prize of the Polish Academy of Sciences in 1997 and a special fellowship from the Foundation for Polish Science in the years 2003-2007. He is a foreign member of Accademia di Scienze e Lettere based in Milano since 2006. In 2005, Professor Spałek received the Polish Order of Merit, the Polonia Restituta Cross from the President of Poland. He was also awarded the Alessandro Volta Silver Medal by Universita di Pavia for his work for the School "European Doctorate in Physics". In the period 2004-10 he was a member of the Science Council to the Minister of Science and Higher Education. For the years 2011-15 he has received a special grant TEAM from the Foundation for Polish Science (FNP). He is also recipient of a prestigous Grant MAESTRO for the years 2012-18 from the National Science Centre (NCN). In 2016 he received the two highest awards in science: the Foundation for Polish Science Prize and Prime Minister Award.
