My research focuses on Astroparticle Physics and rare event searches in underground laboratories, particularly on the direct detection of WIMPs as Dark Matter (DM) candidates and the search for neutrinoless double beta decay (0¿ßß). I completed my PhD in Physics at the University of Zaragoza (UZ) in 2006. I held two post-doc positions: (1) INFN Milano-Biccoca, Italy [2007-2009] (0¿ßß with cryogenic TeO2 detectors, experiments CUORICINO and CUORE-0) and (2) Institut d’Astrophysique Spatiale (IAS), Orsay, France [2009-2011] (DM direct detection with hybrid light-heat cryogenic detectors, EURECA experiment). From 2011 to 2022, I was a tenured researcher at the Aragonese Agency for Research and Development (ARAID). Since 2022 I am a tenured professor (profesora titular) at the University of Zaragoza.
Additional research experience at foreign universities and laboratories includes: 2 months at Universita Roma-Tor Vergata (2005), 2 months at Laboratori Nazionali del Gran Sasso (LNGS, 2007), and 3 years at Universita Roma-La Sapienza (2015-2017).
Currently, I am co-PI of ANAIS-112, a DM direct detection experiment looking for DM annual modulation with 112 kg of NaI(Tl), installed at the Canfranc Underground Laboratory (LSC) in 2017 and taking data since then. The latest results, published in 2021, are the first direct refutation at almost 3 sigma C.L. of the DAMA/LIBRA signal (the only positive dark matter signal in direct detection so far).
Other main contributions:
2010-2014: Characterization with alpha particles of the PLANCK bolometers to determine the origin of the excess deadtime due to cosmic rays.
2015-2020: Analysis of the data from the 0¿ßß cryogenic experiments CUORE-0, CUPID-0, and CUORE (LNGS), including the calculation of the limit to the half-life of 130Te (CUORE: 1.3 x 10^25 years 90%CL).
2015-2020: CALDER experiment at Roma-La Sapienza (readout of cryogenic detectors for 0¿ßß with superconducting kinetic inductance detectors (KIDs), Roma-La Sapienza). Developed MC phonon simulation, analysis software, and data acquisition systems.
2019-present: DArT experiment at LSC (argon radiopurity assessment for DarkSide-20K dark matter experiment at LNGS). Acquisition system coordinator.
2018-present: MC simulation of phonon physics for optimizing bolometric detectors for DM/0¿ßß and other low-temperature devices, like qubits. Studied the loss of coherence in superconducting qubits due to environmental radioactivity and cosmic rays.
I am a member of the DarkSide collaboration, the institutional board of the CUPID collaboration, and the scientific committee of the Spanish Vacuum Society (ASEVA). Since 2020, I am coordinator of the Direct Detection working group of the Multidark Spanish Network and coordinator of the dark matter node of the Spanish Network of Astroparticles (RENATA). Since 2022, I have been a member of the executive committee of CPAN (Centro Nacional de Física de Partículas, Astropartículas y Nuclear) and coordinator of the Astroparticle area.
I am a co-author of over 130 peer-reviewed publications and more than 90 proceeding contributions, with an h-index of 33 (WoS database, ResearcherID K-4827-2012). I have presented my results at over 40 international conferences (over one-third invited) and given invited seminars and lectures at key institutions (~20). I am involved in many outreach activities (International Cosmic Day, Maratón de astropartículas, LSC Open Day, European Research Night, Dark Matter day..)

I have contributed largely to diffuse my results in international conferences (>40, 1/3 of them invited), invited seminars and lectures in key institutions (~20)
I have supervised 1 PhD thesis (Cintas, UZ, 2023) and I am currently supervising other 3 PhD thesis (Pardo, expected in 2025; Apilluelo, expected in 2026 and Perez, expected in 2026) and I have supervised 2 Master and 8 graduate students’ thesis.
