Postdoc

Postdoc at the Lund University. Former PhD student at the Institut de Ciències del Cosmos (ICCUB) at the University of Barcelona.
I study the dynamics of the Magellanic Clouds to understand the evolution and formation of galaxies. To do this I use Gaia data and make idealised pure N-body simulations (KRATOS suite). Currently, I am interested in the Magellanic Clouds as an exciting opportunity to tailor the astrometric requirements of GaiaNIR. I am also a member of the Gaia Data Processing and Analysis Consortium (DPAC) working on the validation of Gaia data at CU9.
