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 200410 he was a member of the Science Council to the Minister of Science and Higher Education. For the years 201115 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 201218 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. In 2019 he received The Marian Smoluchowski Medal in Science, the highest award of the Polish Physical Society. Also, in the same year he has become a member of Academia Europaea.
