Sanna Alwmark

Sanna Alwmark is an Associate Senior Lecturer in the Department of Geology at Lund University. Her research focuses on impact cratering processes, planetary geology, and the application of advanced analytical techniques to study impact structures. She leads projects such as the 'Tracing Catastrophic Collisions' initiative funded by the Crafoord Foundation and the 'Collisional Chaos and Magnetic Mayhem' project supported by the Swedish Research Council.

Her work involves analyzing impact structures like the Siljan and Tvären structures in Sweden, as well as Martian geology through collaborations with NASA's Perseverance rover mission. Key areas of expertise include shock metamorphism, zircon geochronology, and noble gas analysis in impactites.

• Research Interests: Impact cratering dynamics, Martian sedimentology, planetary tomography, and meteoritic classification.
• Grants: Active grants include the Swedish Research Council (Collisional Chaos, 2023–2027) and Crafoord Foundation (Tracing Catastrophic Collisions, 2024–2026).
• Recent Projects: U-Pb dating of the Hummeln impact structure and studies of the Jezero Crater's stratigraphy using RIMFAX radar.

Alwmark has published 37 peer-reviewed articles and co-authored reviews on non-destructive tomography techniques in planetary geosciences. Her work bridges terrestrial and extraterrestrial geology, with a focus on understanding solar system evolution through impact processes.
