About

I am an astrophysicist specialising in the detection, characterisation, and evolution of exoplanets, with a particular interest in young planetary systems and the physical processes that shape planetary populations.

My research combines precision radial velocity measurements, space- and ground-based photometry, and advanced statistical modelling to measure planetary properties and disentangle planetary signals from stellar variability. I develop and apply Gaussian Process methods for the analysis of stellar activity and planetary signals, enabling robust characterisation of planets orbiting active stars.

A central focus of my research is understanding how planetary masses, radii, densities, and atmospheres evolve during the first stages of planetary evolution. By connecting observations of young planets with older planetary populations, I aim to distinguish the physical mechanisms responsible for shaping the diversity of planetary systems observed in the Galaxy.

I contribute to international exoplanet collaborations and observing programmes, including the PLATO mission. Alongside my research, I contribute to scientific software development, international training activities, public outreach, and the wider exoplanet community.
