Academic Background

I am a researcher in astrophysics and cosmology. I work mostly on trying to extract information about fundamental physics from the distribution of galaxies in the Universe and from the statistics of the temperature fluctuations of the so-called Cosmic Microwave Background (CMB), the afterglow of the Big Bang. I am in particular very interested in employing new computational and statistical methods to approach these problems, and in finding novel ways of combining different datasets to learn more about physics. I do most of my work within two international collaborations: the Large Synoptic Survey Telescope and the Simons Observatory.

Undergraduate Teaching

In 2017-2018 I'll be tutor of Quantum Mechanics and Symmetries and Relativity at Christ Church.

Research Interests

Cosmology (large-scale structure, cosmic microwave background, observational cosmology, computational cosmology, dark-energy models). Fundamental physics (general relativity, quantum field theory, particle physics). Mathematics (differential geometry, group theory, functional analysis, statistics).


I have published scientific articles on topics mostly related to cosmology and fundamental physics. More information can be found here


Hiking, running, programming and beer.
