I am a Juan de la Cierva postdoctoral fellow at the Institut de Física d'Altes Energies in Barcelona, Spain. I'm interested in the major questions in cosmology: what are dark energy and dark matter? How can the large-scale structure we observe today tell us about the past and future of the universe?
I focus on studying the large-scale network of matter in the universe called the Cosmic Web. I'm interested in the information that the complex extended structures within this "web," such as filaments and superclusters, hold about the history of our universe. By working at the intersection of simulations and observations, I aim to increase the information we can extract from existing data and preparing for future sky surveys.
Below are the four main projects I am currently working on.
Working within the Cosmo-LYA group at IFAE and the DESI Ly-α working group, I am making measurements and inferring cosmological and intergalactice medium physics from the P× ("P-cross") statistic: the correlations between separated lines-of-sight of Lyman-α absorption at redshifts 2-4.
In this paper, I generated new Websky simulations for different cosmological and gas parameters, and tested the sensitivity of oriented stacks to the varied parameters. I am continuing to test the power of various directional- and environmentally-dependent statistics to alternative cosmologies.
In works like "Boundless baryons: how diffuse gas contributes to anisotropic tSZ signal around simulated Three Hundred clusters" and "Here, There and Everywhere: How AGN jets affect galaxy cluster environments", collaborators and I are using hydrodynamic simulations to explore how feedback mechanisms, like AGN jets, affect the state of gas in the warm-hot intergalactic medium in proto-cluster environments.

I am making measurements of filamentary structure by combining data from the Atacama Cosmology Telescope (ACT) and the Dark Energy Spectroscopic Instrument (DESI), and comparing them to simulations.
