معرفی
Nikolaj Louis Dahmen is a Lecturer at the Institute of Geophysics, ETH Zurich, within the School of Earth and Planetary Sciences. His research focuses on Martian seismology, leveraging data from NASA’s InSight mission to analyze seismic activity and crustal structure. Dahmen specializes in applying machine learning techniques for seismic denoising and event detection, significantly expanding the catalog of marsquakes and improving their analysis. He earned his Doctoral Thesis in 2024, titled 'The Seismicity of Mars Recorded by InSight,' supervised by Prof. Domenico Giardini. His work addresses challenges in low-signal-to-noise ratio environments and contributes to understanding Martian tectonic processes.
- Education: Doctoral Thesis (2024) at ETH Zurich
- Key Research Areas: Planetary seismology, machine learning applications, seismic data processing, Martian crustal structure
Dahmen’s research has led to advancements in detecting and cataloging marsquakes, including the discovery of the largest recorded marsquake (S1222a). His methods enhance seismic signal analysis by mitigating environmental noise, enabling precise event localization and waveform interpretation. Collaborations include the Marsquake Service (MQS) and projects like MarsQuakeNet, which automate event detection using deep learning.
His contributions extend to crustal studies through surface wave analysis and meteorite impact investigations, providing insights into Mars’ subsurface composition. Dahmen’s work bridges planetary science and computational methods, advancing our understanding of Mars’ geophysical dynamics.
