Hello

I am an expert in high-precision spectroscopy of Sun-like and M dwarf stars. This technique enables the determination of robust stellar properties such as atmospheric parameters, ages, stellar activity, radial velocities, and rotation. Since 2016, I have been working on how stars like our Sun produce magnetic fields, and how these magnetic fields and stellar rotation evolve over the stars lifetimes.

My research interests

The major goal of my research is to place our own Sun into context to better understand the origins and evolution of its magnetic fields. The interplay between stellar rotation, activity, and age drives the dynamo evolution and has applications in many areas of astrophysics. For instance, the magnetic variability of stars is currently the dominant obstacle to discovering Earth-like planets. I addressed the long-standing issue of the magnetic evolution of old stars that was first questioned 18 years ago. I provided solid evidence that stellar activity and rotation can be used as reliable chronometers for solar analogs. I have published 24 peer-reviewed articles, including 14 as first author or major contributions (H-index=14, Google Scholar) in high-profile journals. From the observational side, I had a crucial experience involving observations, project development, pipeline construction, and data analysis. My projects have been approved in several telescopes worldwide (notably 14 nights of HARPS time awarded as PI). I have given 11 invited talks worldwide (including NASA, ESO, AIP-Potsdam, and Exeter) and contributed talks at international conferences. Recently I have been invited to give a review talk about stellar chromospheric chronometers at the conference Fifty Years of the Skumanich Relations, celebrating the 50th anniversary of the most impactful paper in my area of research (Skumanich, 1972, ApJ, 171, 565).
