About
Prof. Ingo Leya is a Professor at the Department of Space Research & Planetary Sciences at the University of Bern. His research focuses on cosmic ray physics, meteoritics, and planetary science with emphasis on cosmogenic nuclide dating, isotopic analysis of meteorites, and early Solar System processes. He leads studies on terrestrial age determination of meteorites using 14C and 10Be systems, and investigates irradiation effects in calcium-aluminum-rich inclusions (CAIs) and chondrules.
Key research topics include the shielding dependence of cosmogenic isotopes, spatial origins of micrometeorites, and lunar magma ocean solidification. His work integrates experimental data with advanced computational models, such as Bayesian parameter optimization for spallation processes. Leya’s team operates cutting-edge facilities like the MASCOT mass spectrometer for cosmogenic noble gas analysis and the EGT time-of-flight spectrometer for multielement isotope analysis.
Recent projects address pre-accretionary irradiation effects in Allende meteorites, potassium isotope studies in iron meteorites, and the constancy of galactic cosmic rays over time. His research contributes to understanding Solar System formation, planetary evolution, and cosmic ray exposure histories of extraterrestrial materials.
