About Me

Hello! I'm Arthur Loureiro, a researcher interested in Observational Cosmology. My research focus is Large Scale Structure of the Universe, Fourier analysis of Galaxy Surveys, Neutrinos in Cosmology, Bayesian Methods applied to Observational Cosmology, and cross-correlations between photometric and spectroscopic surveys.
In other words, I am a data scientist with a strong passion for Cosmological data.
Currently, I am an active member of the Euclid Consortium.

When I'm not using images of the sky to study the fundamental physics of our Universe, I'm using my (much smaller) camera to take pictures of the streets around me.


A summary of the scientific projects and collaborations I am working with.

Some sort of CV.

  • 2009-2013

    Undergraduate (UFRGS)

    Porto Alegre - Brazil
    I graduated in Physics with emphasis in Astrophysics at the Universidade Federal do Rio Grande do Sul in my hometown.

  • 2012

    Undergraduate Exchange (UdeM)

    Montréal - Canada
    Under the Science Without Borders Undergraduate fellowship, I pursed an exchange at the Université de Montréal during one semester.

  • 2013-2015

    Masters (USP)

    São Paulo - Brazil
    I did my masters in Physical Cosmology at the Department of Mathematical Physics at University of São Paulo under the supervision of Prof. Luis Raul Abramo.

    PhD (UCL)

    London - United Kingdom
    I obtained my PhD at the Department of Physics & Astronomy at University College London working with Dr. Bruno Moraes, Prof. Ofer Lahav, Dr. Lorne Whiteway and others. My thesis was entitled "The Universe in Harmonic Space: Neutrinos and Dark Energy".

  • 2019

    Euclid Research Assistant (UCL)

    London - United Kingdom

    I have worked in a 12 months post-doc with Dr. Benjamin Joachimi at University College London to develop and validate Weak Lensing analysis pipelines for the future Euclid Mission.

  • 2019-2020

    Research Associate (Imperial College)

    London - United Kingdom
    I am working on a short project at Imperial College London with Prof. Alan Heavens and Prof. Andrew Jaffe; we are currently developing a bayesian hierarchical model for power spectra estimation on the sphere.
