I am an observational astrophysicist with broad, multidisciplinary interests spanning supernova physics, stellar and galaxy evolution, and cosmology. I obtained a PhD in Physics from the Universitat Autònoma de Barcelona in 2011 under the supervision of Prof. Ramon Miquel at the Institut de Física d’Altes Energies (IFAE). I have held postdoctoral positions at CENTRA/IST in Lisbon under the supervision of Dr. Vallery Stanishev and Prof. Ana M. Mourão, as a FONDECYT postdoctoral fellow at the Astronomy Department of the Universidad de Chile working with Prof. Mario Hamuy, as a research associate in the Department of Physics and Astronomy at the University of Pittsburgh with Prof. Michael Wood-Vasey, and as a Marie Sklodowska-Curie fellow at the Universidad de Granada, integrated in Prof. Inma Domínguez’s group. After a couple of years as a Ramón y Cajal Fellow, I am currently a Científico Titular at the Institute of Space Sciences (ICE-CSIC), also affiliated with the Institut d’Estudis Espacials de Catalunya (IEEC). During my career in astrophysics, I have been concerned with key observational aspects of supernova (SN) science that have a direct impact on other fields of astrophysics such as stellar evolution, galaxy enrichment, and cosmology. The prime goal of my research is to deepen the understanding of the systematic uncertainties in the SN light-curve standardization for measuring cosmological distances by using the information retained in their environment. My research has significantly advanced our knowledge regarding the characteristics of the local environment of SN and their connection with the observed SN properties, as well as the characterization of their progenitor systems. The topics I have been investigating can be listed as: (1) Improving the use of SNe Ia as distance indicators; (2) Characterizing SN Ia subgroups; (3) Constraining SN progenitors via Integral Field spectroscopy of their environments; and (4) Exploring multiple alternative probes to measure extragalactic distances. Although these topics cover different scientific goals, they share a common drive to develop innovative data mining techniques and can be handled with the same kind of observations. In addition to these main lines of research I have also been contributing to i) understanding the nature of the extragalactic extinction towards SN observations, which is another important source of uncertainty in SN standardization; ii) a wide range of galaxy enrichment, formation, and evolution studies; and iii) observation and interpretation of gravitational wave counterparts. In the near future I would like to break new ground in these fields in various directions. So far, I have published 423 articles, 13 as a first and 17 as a second author (most led by students I mentored), with over 27,000 citations and an h-index of 73 (ADS, Feb 2025). My work has been presented at international conferences giving more than 82 talks, including 35 invitations to deliver seminars at different institutions. I have been the PI of 93 successful observational proposals, awarded on a competitive basis at the largest observatories worldwide, and have actively participated in more than 100 other observational campaigns. I have led analyses within major international collaborations (SDSS-II SN, CALIFA, PESSTO, DES, HSC-SSP, MaNGA, J-PLUS, LSST, ROMAN, DESI, ZTF, LS4), including PISCO and AMUSING in which I am the PI. I had the opportunity to mentor 15 graduate students, and 14 undergraduate students, including two funded 3-month PhD research visits and 2 ERASMUS+ undergraduate programs, directed 9 of them in their Master thesis (TFM) and 6 of them in their Bachelor final project (TFG). I currently supervise 6 PhD students (3 of which co-supervised) and 3 postdocs at ICE. I have been in the LOC/SOC of 5 conferences and led the organization of up to 11 workshops focused on SN science topics (including two Special Sessions at EAS 2020 and 2024, and one at SEA 2024).
