Rate My Professor Jens Jasche

Dr. Jens Jasche is a Senior Lecturer and Associate Professor in the Department of Physics at Stockholm University, where he is affiliated with the Oskar Klein Centre. He began his academic career with a physics diploma from Leibniz University of Hannover, researching the impact of cosmic rays on the formation of the first stars. He then completed his Ph.D. in physics at Ludwig Maximilian University of Munich, conducting his doctoral studies at the Max Planck Institute for Astrophysics, where he pioneered the field of cosmic field-level inference. This groundbreaking work enabled the reconstruction of the spatial distribution of cosmic structures and their gravitational formation history from large-scale galaxy surveys. Following his doctorate, Jasche held postdoctoral positions at the Argelander Institute for Astronomy in Bonn, the Institut d’Astrophysique de Paris supported by a Feodor Lynen Fellowship from the Alexander von Humboldt Foundation, and the Excellence Cluster Universe in Munich. In recent years, he has been appointed AI Coordinator for the Faculty of Science at Stockholm University.

Jasche's research focuses on observational cosmology, cosmic large-scale structure formation, dark matter, and dark energy, utilizing advanced Bayesian inference, machine learning, and statistical techniques to explore the origin and evolution of the universe. He founded the Aquila consortium, an international collaboration advancing cosmological inference through innovative methods, and leads efforts in creating digital twins of the universe. His contributions appear in major collaborations like Planck, Euclid, and SDSS, with key publications including 'Bayesian physical reconstruction of initial conditions from large-scale structure surveys' (Jasche & Wandelt, 2013, MNRAS), 'Physical Bayesian modelling of the non-linear matter distribution: new insights into the Nearby Universe' (Jasche & Lavaux, 2019, A&A), and 'Fast Hamiltonian sampling for large-scale structure inference' (Jasche & Kitaura, 2010, MNRAS). Jasche is an IAA Elected Fellow since 2020 and teaches courses such as Statistics for Physicists and Machine Learning for Physicists and Astronomers. His interdisciplinary approach fosters mentoring of next-generation cosmologists and public outreach.
