Profile
I am a UKRI Future Leaders Fellow and a lecturer in cosmology at Queen Mary University of London. My main research interest is cosmology with radio and optical galaxy surveys, mainly the Euclid satellite mission and MeerKAT/SKA.
I completed my PhD at the University of Nottingham in 2011, followed by a postdoc at the Univesrity of Manchester (2012), a postdoc at Bologna University (2014), and a Dennis Sciama Fellowship at the Institute of Cosmology & Gravitation in Portsmouth (2017). I have an MSc in Elementary Particle Theory from Durham University and a degree in Physics from the University of Athens.
My Github repository with code and lecture material.

Project Title
Cosmology Theory Meets Data: Modelling Non-Linear Scales for Dark Energy Experiments
During the last few years, we have entered the “golden era” of observational cosmology. The standard cosmological model fits the data extremely well, but requires the existence of two exotic constituents, namely dark energy in the form of a cosmological constant, and cold dark matter. Dark energy currently dominates the Universe and it is responsible for its accelerated expansion.
