I'm a final-year PhD candidate at the Instituto de Física Teórica (IFT UAM-CSIC) in Madrid, working on the largest scales in cosmology: the shape of the Universe, tests of the Cosmological Principle, and higher-order statistics of the CMB and galaxy surveys. I lead the Euclid team measuring the cosmic dipole and am a core member of the COMPACT Collaboration. I'm looking for postdoctoral positions starting in autumn 2027.
Research Interests
Collaborations
I have been part of the Euclid collaboration since 2024, when I joined the Homogeneity & Isotropy work package within the Theory Working Group.
I lead and coordinate the group of people within Euclid trying to measure the kinematic dipole using an Ellis & Baldwin test approach. The unprecedented quality and size of the Euclid photometric sample will allow us to make a first-of-its-kind measurement to test one of the fundamental assumptions in our field: the Cosmological Principle.
The COMPACT Collaboration is a group of ~25 cosmologists of different backgrounds and levels of seniority trying to answer one of the most basic yet profound questions about our Universe: what's its shape?
Since joining at the start of my PhD, I have worked on how the shape of the Universe would show up in the CMB, and I am currently leading a paper on lens spaces. I have also studied how much information the CMB and the 3D distribution of matter carry about topology, and how topology affects quantum fields. I am a co-author of our review The topology of the Universe in Nature Astronomy (2026).
About Me
Hi there!
I am originally from Hernani, a town in the Basque Country (northern Spain).
For my undergrad I spent 5 years at Universidad de Cantabria (Santander), completing a double degree in Physics and Mathematics.
From there I moved to Madrid to do my Master's at IFT, where I stayed afterwards to pursue my PhD in theoretical and computational cosmology.
Short-term goals include: running a sub-34 minute 10K, traversing the Pyrenees along the GR-11 and finding a postdoc.
