My research has been focused mostly on the Dark Energy Survey (DES) and more recently on the Dark Energy Spectroscopic Instrument (DESI). I lead the DES galaxy evolution working group, and the DESI time domain working group.
My main interests include gravitational waves, ‘ripples’ of spacetime that are produced, in the most violent cases, by catastrophic events such as black holes or neutron stars merging. I am involved in the search of the sources of these events with DES, more generally with DECam and other instruments, and I use host galaxies data to understand the formation of these sources and the expansion of the Universe.
Another of my science interests is galaxy clusters, and how galaxies evolve within them. Clusters of galaxies are the largest gravitationally bound structures in the universe and they carry a lot of interesting information about gravity, the universe, and the galaxies within them. I "weigh" galaxy clusters using the light from clusters galaxy members that we see through DES data. I study how much mass in clusters ends up building stars and how this relates to the total cluster mass, mainly the dark matter that we do not directly see from DES. Such estimate is a first step towards inferring cosmological parameters using the abundance of galaxy clusters.
