Research Interests

I am currently undertaking my PhD thesis on "Tomographic Coupled Dark Energy with Euclid", under the supervision of Dr Valeria Pettorino. I am interested in studying modified LCDM models, specifically coupled quintessence models, by investigating their potential in alleviating tensions in cosmology. We foresee the ability to integrate such LCDM model extensions into the Euclid likelihood pipeline. 

I also work with Dr Martin Kilbinger to look at cosmic shear systematics in CFIS/UNIONS, ultimately aiming to develop a likelihood analysis pipeline to conduct cosmological parameter estimation with UNIONS shear data.

I am part of the Euclid and CFIS/UNIONS collaborations, and am involved in the PHC Pessoa Exchange with the Costar lab at CENTRA, Instituto Superior Técnico, Lisbon. I am also one half of the Cosmostat Journal Club organising committee: if you would like to give a seminar at the lab, please feel free to contact Denise or me!
