Dennis Stello

Professor Dennis Stello is a Professor at the University of New South Wales (UNSW) in the School of Physics. He earned his PhD in Astrophysics from the University of Sydney (2006), MSc in Astronomy from Aarhus University (2002), and BSc in Math/Physics from Aarhus University (2000).

Professor Stello leads the Asteroseismology Group at UNSW, focusing on stars, planets, and the Milky Way. His research utilizes asteroseismology—vibrations from star quakes—to infer the physical properties of stars. His group is pioneering the development of Artificial Intelligence software to analyze large complex datasets from NASA space missions like Kepler and TESS, extracting intricate signatures of stellar vibrational frequencies.

His recent publications (2023-2025) demonstrate a strong emphasis on asteroseismology of red giants and subgiants, stellar evolution, galactic archaeology, and advanced data analysis techniques. His work frequently involves major international collaborations and utilizes data from surveys like GALAH and space missions including TESS and Kepler, significantly advancing our understanding of stellar structure and galactic evolution.

Professor Stello has made substantial contributions to the field through his leadership in asteroseismology research and numerous publications in top astronomy journals. His work has refined methods for determining stellar ages, masses, and evolutionary states using asteroseismic techniques.

He leads an active research group that develops AI-driven tools for stellar data analysis and collaborates with international teams on major astronomical surveys. His laboratory work focuses on processing and interpreting data from space-based observatories to extract fundamental stellar parameters and understand galactic evolution through galactic archaeology approaches.
