I study the nature of dark energy from observational measurements of the shapes of galaxies. A phenomenon known as gravitational lensing distorts galaxy shapes and allows us, through its measurement, to study the composition and evolution of the Universe.

 

Gravitational tides can also leave a mark on galaxy shapes, and I have been studying them from multiple perspectives: analytical, numerical and observational to figure out why, how and which galaxies align across the structure of the Universe and how this interplays with the lensing effect.

I am involved in several major astronomical surveys, such as the ongoing Kilo-Degree Survey, and the upcoming Vera Rubin Observatory and Euclid. Within Rubin Observatory, I am most active in the LSST Dark Energy Science Collaboration, where I am currently "Deputy Analysis Coordinator" for cosmology with static probes.
