Born in Castellón, Spain, on November 9, 1966. PhD in Physics from the University of Valencia (UV) in 1994 (supervised by Prof. J.M. Ibáñez). After postdoctoral appointments at the Max Planck Institute for Gravitational Physics (Potsdam) and the Max Planck Institute for Astrophysics (Garching), I joined the University of Valencia, where I was Associate Professor from 2003 to 2018 and where I am currently Full Professor since 2018. I served as Head of the Department of Astronomy and Astrophysics (2015–2018) and have been UV group leader in the Virgo Collaboration since 2016, currently serving as Chair of the Virgo Editorial Board. I lead the Gravitational Wave and Numerical Relativity research group at UV.

My research focuses on Relativistic Astrophysics, Numerical Relativity, and Gravitational-Wave Astronomy. My work has received wide international recognition. Results from my research are implemented in numerical-relativity codes based on high-resolution shock-capturing schemes and are used by most numerical relativity groups worldwide. The relativistic hydrodynamics and magnetohydrodynamics formulation developed by our group (known as the Valencia formulation) has become a standard in the field of numerical relativity. I have published around 300 peer-reviewed articles and given over 80 international conference talks. My H-index is 94 (NASA ADS, as of January 2026).

I have led and participated in numerous national and European research projects, contributed to widely used numerical-relativity codes (GR3D, CoCoA/CoCoNuT, Nada, CACTUS/WHISKY, Einstein Toolkit), supervised or co-supervised 11 PhD theses, and regularly serve as reviewer for major funding agencies and leading journals. I am active in scientific outreach and have chaired major international conferences, including the 2019 GR22–Amaldi 13 conference in Valencia.

He obtained his PhD in Physics from the University of Valencia in 1991 and subsequently carried out a long postdoctoral stay (1991–1995) at the Max Planck Institute for Astrophysics (MPA, Garching, Germany), funded by a postdoctoral fellowship from the Spanish Ministry of Education and Science and a Marie Curie contract from the European Commission. The research conducted at MPA (1993–1995) was selected by the European Commission for its “particular interest”. He is currently Full Professor of Astronomy and Astrophysics at the University of Valencia.

He has published more than 80 papers in indexed journals (over 20 in the last decade), with 4899 citations, an h-index of 40 and an I100 index of 18 (ADS). His scientific output averages 125 citations per year (213 citations per year over the last ten years) and an average of four authors per publication. He holds six research merit periods (“sexenios”).

His main research lines include: (1) numerical methods in relativistic hydrodynamics and magnetohydrodynamics, (2) the physics of extragalactic jets, and (3) magnetic fields in Cosmology. He has participated uninterruptedly in competitive research projects since 1987, contributing to the establishment and consolidation of the Relativistic Astrophysics group at the University of Valencia. After returning from MPA, he initiated within the group the research line on extragalactic jets. Since 2007, he has also participated in Cosmology projects, studying the influence of jets on galaxy evolution and the evolution of the primordial magnetic field. In 2022 he contributed to the creation of the new research group High-Energy Outflows in Astrophysics.

Throughout his academic career, he has taught Mathematics in several engineering degrees, as well as Algebra and Geometry, Fluid Physics and Astrophysics in the Physics degree. He has taught courses on Numerical Techniques in Astrophysics and Computational Astrophysics in various master’s programmes. He is co-author of an Algebra and Geometry textbook published by the University of Valencia. He is the local coordinator of the Double Degree in Physics with Johannes Gutenberg University Mainz (Germany). He has coordinated the organisation of several Physics Summer Schools in collaboration with various European universities in the Forthem Alliance. He holds six teaching merit periods (“quinquenios docentes”).

He has supervised or co-supervised four PhD theses. He has also held several academic management responsibilities, including serving as Secretary of the Department of Astronomy and Astrophysics for more than five years (2001–2006) and as Head of the same department for six years (2006–2012). Since November 2022 he has been Vice-Dean for Quality and Internationalisation at the Faculty of Physics.

[Biography, english version]

My main scientific research focuses on stellar structure and evolution and on the characterisation of exoplanetary systems. I lead two main research lines: (1) stellar characterisation using Machine Learning and Artificial Intelligence techniques, and (2) non-linear asteroseismology in classical pulsating AF-type stars. Since completing my PhD in 2003, I have published nearly 104 papers and book chapters, around 67 of them in first-quartile international journals (more than 4,500 citations, h-index = 35, according to ADS). I am first author of 16 publications, 11 of them in first-quartile journals (378 citations, h-index as first author = 12). These works cover topics ranging from exoplanet characterisation and habitability to stellar characterisation using ML/AI, as well as theoretical and observational asteroseismology. I am also the developer of one of the most up-to-date stellar pulsation codes, GraCo. I collaborate in two ongoing international projects focused on the detection and characterisation of exoplanets orbiting K-type stars. These results have been presented at more than 60 international conferences, including six invited talks, and I have delivered 18 seminars at international research centres.

Since September 2025, I have been a Senior Lecturer at the University of Valencia. Between 2021 and 2025, I held a contract for excellent researchers at the University of Valencia, funded by the Generalitat Valenciana under the GenT programme. This project enabled the creation of a new research group within the Department, led by me and devoted to asteroseismology and stellar characterisation. Previously, I was an Ayudante Doctor at the Polytechnic University of Madrid (2019–2021) and a Marie Skłodowska-Curie Individual Fellow at the University of Birmingham (2017–2019). Earlier in my career, I held several postdoctoral positions at the Instituto de Astrofísica de Andalucía–CSIC (2000–2004, 2006–2009), the Centro de Astrobiología–INTA/CSIC (2009–2013), and the Observatoire de Paris–Meudon (2004–2006), including a Juan de la Cierva fellowship.

I have been involved in nearly all major space missions related to asteroseismology and exoplanet science, including CoRoT (France/ESA), Kepler and TESS (NASA), and Cheops, Ariel, Plato, and HAYDN (ESA). I have led several work packages in CoRoT and Plato, and in particular, within Plato, I am responsible for the MSAP1 module (one of five) of the stellar pipeline. I am currently the Spanish Principal Investigator (PI) of the ESA mission proposal HAYDN, which was submitted to the ESA M7 call, reached Phase 0/CDF, and has been resubmitted to the ongoing ESA M8 call. HAYDN aims to perform asteroseismology in open and globular clusters. Spain is the third-largest contributor to this mission, and I am a member of its core team. I am also PI of the Spanish National Project “IP y coordinador en España de la propuesta de misión espacial M de la ESA, HAYDN”. Previously, between 2010 and 2012, I was the PI of the ESA S-mission proposal PlanetVision, an international project on exoplanetary system characterisation involving six countries, 25 institutions, and over 125 researchers, with Spain as both the scientific leader (under my coordination) and the industrial prime. PlanetVision reached the final evaluation stage, although the selected mission was Cheops.

My teaching experience includes courses at the Polytechnic University of Madrid, the University of Valencia, the University of Birmingham, and the Valencian International University (VIU), where I served as Head of the Master’s programme in Astronomy and Astrophysics. I have co-supervised two PhD theses and am currently co-supervising and mentoring two additional PhD candidates. In addition, I have supervised 10 Master’s theses and participated in eight PhD examination committees, as well as numerous Master’s and Bachelor’s thesis juries. In terms of outreach, I have written several popular science articles in magazines and blogs, including one that appeared on the cover of AstronomiA Magazine (December 2017). I have also delivered outreach talks and seminars in various initiatives (e.g. Pint of Science, Pub La Goma) and participated in public engagement events such as Caos y Ciencia, Expociencia, and Open Days at the University of Birmingham.

I regularly serve as a referee for international journals (including MNRAS, A&A, ApJ, ApJ Letters, New Astronomy, and Physics and Astronomy Reports) and as a member of Time Allocation Committees for facilities such as the Hubble Space Telescope (Cycle 27), the Liverpool Telescope, and the James Webb Space Telescope (Cycles 2 and 3). I am also a reviewer for the European Commission and the Spanish State Research Agency (AEI), including programmes such as Juan de la Cierva and the National Space Plan. I have organised more than ten international conferences as a member of the Scientific and/or Local Organising Committees (including the Iberian Meetings in Asteroseismology I–X and special sessions at EAS meetings), chairing three of them.

Finally, I am a member of the European Astronomical Society (EAS), the Spanish Astronomical Society (SEA), the International Astronomical Union (IAU), and the Royal Spanish Society of Physics (RSEF). Between 2013 and 2015, I also worked in the R&D department of the private company SapTools, focusing on Big Data analysis.
