Dr. Johann Rafelski, theoretical physicist, formerly a scientist at CERN, Professor at the Universities of Frankfurt and Cape Town, Guest Professor in Paris and Munich, has been working for more than 35 years at The University of Arizona (Tucson, USA). He works in several disciplines of subatomic physics to further the understanding of the nature of the quantum vacuum. He investigates the behavior of matter under extreme temperature conditions and the effects of the strongest forces both in laboratory experiments and in early Universe. He is also pursuing nuclear `table-top' fusion and has contributed to development of numerical neural activity models. Rafelski is author or editor of more than a dozen (text)books and author of 400+ research works. Dr. Rafelski is a Fellow of the American Physical Society (APS), a Fulbright Fellow Summers of 2019 to 2021, hosted by the Wigner Research Center for Physics in Budapest, elected foreign member of the Academia Europea, and Hungarian Academy of Sciences. He has been elected to the Senate of The University of Arizona for the periods 2018-2020-2022 representing his College of Science and in 2023-2025 representing general University faculty.
