I am a physicist and I work on cosmology, astrophysics and data analysis in roles that bridge people with different expertise.
I work on using data from ground and space missions to test theoretical models that describe the evolution and content of the Universe. Topics I have been working on include: Dark Energy, Dark Matter, Modified Gravity, Cosmic Microwave Background, Neutrinos, Supernovae. I have coordinated the Planck analysis for Dark Energy and Modified Gravity and I lead the Inter-science Taskforce for forecasts and Likelihood within the  ESA Euclid international space missions.
