Maria is an expert in stellar spectroscopy and stellar atmospheres. She developed methods and pipelines to characterize stars, including the use of machine learning techniques. She is interested in the chemical evolution of the Galaxy and the origin of stellar populations. In particular, she studies the statistical properties of exoplanets and their hosts. She is postdoc at INAF-Arcetri working on the scientific preparation and conceptual study of HRMOS. Her postdoc is funded by the INAF-Large grant. 

Riano is an expert in stellar spectroscopy, usign methods that provde very precise stellar parameters and stellar ages, in particular in the metal poor regime. He has a wide expertise in the determination of heavy element abundances. He devlopperd a method permit to diagnose the the dominance of the different neutron capture processes responsible for the nucleosynthesis of the heavy elements. He is postdoc at INAF-Arcetri working on the conceptual study for the realisation of HRMOS. His postdoc is funded by the PRIN-MUR 2022.  

José is a young stellar astrophysicist with expertise mainly in the chemical characterisation of stellar clusters using different spectroscopic techniques. He is postdoc at INAF-Arcetri working on the conceptual study for the realisation of HRMOS. We participate to the design and realization of the HRMOS ETC.  His postdoc is funded by the PRIN-MUR 2022.  

Leda Berni is a PhD student in our group. She is working on the survey plan strategy for WST, and on the characterisation of the Galactic halo stellar populations. She already published her first paper! 

Camilla is the recipient of the INAF Astrofit 2023 fellowship (first place) and a leading expert on the connections between stars and planets. At the Arcetri Observatory, she works on a variety of topics, including leading the group characterizing the host stars for the Ariel space mission. Starting September 2025, Camilla will take up a permanent position in Valencia. Congratulations, Camilla!

Marco is a postdoctoral researcher at the University of Bologna and will join our group in November 2025. He received his PhD in 2022 from the University of Trieste, with a thesis focused on chemical evolution modeling across diverse cosmic environments, ranging from the Milky Way to high-redshift systems.

Our collaboration focuses on reconstructing the Milky Way’s past history by comparing chemo-dynamical models with open cluster data. During his postdoctoral tenure at Arcetri, Marco will contribute to the preparation of the WST Survey Plan.

Mathieu's research focuses on two main themes: the search for binary (or multiple) systems and the use of high-resolution spectroscopy for the study of abundance in particular of electron capture elements. Mathieu has dedicated the last few years to the Gaia-ESO survey and the preparation of pipelines for analysing the data from WEAVE and 4MOST. His postdoc was funded by INAF-WEAVE.
