Hello! I am a La Caixa Junior Leader fellow. During my stay at ICCUB, I aim to reveal the mysterious formation channel of metal-rich RR Lyrae stars. The RR Lyrae are a well known class of variable stars with periods between 0.2 and 1 day. They are usually found in old and metal-poor envoroinment, however a substantial metal-rich population has been recently found in the Milky Way disk. The existence of such stars challenges our current understanding of stellar evolution. I will produce the first comprehensive study of these objects from both theoretical and observational point of view. The solution to this problem will have an important impact not only on the study of RR Lyrae, but also on the stellar and binary evolution models, and on the formation and evolution of our Galaxy. Apart from my main focus, my research interests and expertise span a wide range of topics including the study of the property, formation and evolution of our Galaxy and its neighbourhood (I am part of the WEAVE collaboration), the study of HI kinematics in external galaxies, stellar and binary evolution processes, and the astrophysical interpretation of gravitational weave (I am part of the LVK, Einstein Telescope, and LISA collaborations). I also very active in scientific software development. In particular, recently I released a new state-of-the-art population synthesis code (SEVN, https://gitlab.com/sevncodes/sevn). I am interested in testing machine learning/deep learning methods applied to astrophysical problems. I am open to collaborations (including interdisciplinary projects). If you find my expertise useful and/or you just want to chat about projects pass by my office or contact me. I enjoy supervising students. If you are one of them and you are interested on the topics I work on don't esitate to contact me.
