Research Topics
My research interests focus on the large-scale structure (LSS) of the Universe. I am not only interested in these structures themselves, but also their roles in the evolution of galaxies and supermassive black holes, using LSS to probe the nature of dark energy and new physics, and new observational, computational and statistical tools for investigating LSS. Here is an overview of my main research topics.
Cosmology with Large Scale Structure (BAO & DESI)
The Universe is expanding, and its expansion is accelerating. To understand why, we map the 3D distribution of millions of galaxies. By studying the patterns in this cosmic web—specifically a feature called Baryon Acoustic Oscillations (BAO)—we can measure the expansion history of the Universe. I work within the Dark Energy Spectroscopic Instrument (DESI) collaboration to extract precise cosmological measurements from these vast cosmic maps.
Weak Gravitational Lensing
Most of the mass in the Universe is invisible dark matter. Although we cannot see it directly, we can feel its gravity. According to Einstein’s General Relativity, massive objects bend the space around them, distorting the light from distant background galaxies. This effect is called weak gravitational lensing. I use this “cosmic mirage” to weigh dark matter halos and study how structures form and grow over cosmic time.

Black Hole and Galaxy Evolution in the Context of Large-Scale Structures
Galaxies and their central supermassive black holes do not evolve in isolation; they are deeply influenced by the enormous dark matter halos that surround them and the broader large-scale structure of the Universe. By combining galaxy surveys with weak lensing, I measure the dark matter halos of Active Galactic Nuclei (AGN) and study how these central black holes co-evolve with their host galaxies across cosmic time.
