Prof. Jürg Fröhlich | Best Researcher Award

ETH Zürich | Switzerland

Jürg (Martin) Fröhlich is Professor Emeritus of Theoretical Physics at ETH Zurich, renowned for his foundational contributions to mathematical physics, quantum field theory, and statistical mechanics. He earned his Diploma (1969) and Ph.D. (1972, with honors) in Theoretical Physics from ETH Zurich under Professor Klaus Hepp, focusing on the infrared problem in nonrelativistic quantum field models. Following his doctoral studies, he held academic positions at the University of Geneva, Harvard University, Princeton University, and the Institut des Hautes Études Scientifiques (IHES), before joining ETH Zurich in 1982, where he later helped establish the Pauli Center for Theoretical Studies. His research has profoundly influenced the understanding of phase transitions, localization phenomena, gauge theories, and topological phases of matter. Professor Fröhlich has published over 400 scientific papers, with more than 31,000 citations and an h-index of 91. He has received numerous prestigious honors, including the National Latsis Prize, the Dannie Heineman Prize for Mathematical Physics, the Marcel Benoist Prize, the Max Planck Medal, and the Henri Poincaré Prize. He is a Fellow of the American Mathematical Society, a member of the Academia Europaea, and an International Member of the U.S. National Academy of Sciences, reflecting his lasting influence on mathematical and theoretical physics.
