ASTRONOMY

My research focuses on high-energy and relativistic transients: short-lived astronomical events that provide unique opportunities to study some of the most extreme environments in the Universe.

A major part of my work is devoted to gamma-ray bursts (GRBs) and their optical and near-infrared counterparts, with a particular interest in their early-time emission. By observing these events as rapidly as possible after their discovery, I study the physics of relativistic outflows, the interaction of the ejecta with their environment, and the mechanisms powering their afterglows.

I am also interested in the growing diversity of fast and unusual transients being uncovered by modern surveys and high-energy missions. My research includes fast X-ray transients (FXTs) and fast blue optical transients (FBOTs). An important part of this work is determining how these events relate to the known populations of stellar explosions and compact-object mergers.

Much of my work relies on rapid-response observations with facilities at the Observatorio Astronómico Nacional in San Pedro Mártir, Mexico, including COATLI and DDOTI, as well as COLIBRÍ, a 1.3-m robotic telescope designed for the rapid study of transient phenomena.

I also use observations from major international facilities, including the Very Large Telescope (VLT), the Gran Telescopio Canarias (GTC), the VLA, Chandra, HST, Swift, Fermi, and Einstein Probe.

My work combines rapid observations, multi-wavelength data analysis, and physical modeling to understand the origin and evolution of these transient sources.

I regularly participate in national and international conferences, workshops, and collaborations devoted to high-energy and time-domain astrophysics. In 2026, I organized the COSPAR scientific session “"Exploring the Zoo of Transients in the Era of Big-Data Astronomy") in the COSPAR 2026 in Florence, Italy. ” in Florence, Italy.

I am also involved in organizing scientific meetings and activities that bring together researchers and students working on transient and high-energy astrophysics. For example Deciphering the Violent Universe). 

One of the things I enjoy most about astronomy, besides discovering something new about the Universe, is sharing it with others. I regularly participate in outreach talks, public workshops, and science-communication activities aimed at making astrophysics accessible beyond the research community.

For me, research and outreach are closely connected: the excitement of observing an explosion billions of light-years away is even better when you can explain why it matters to someone seeing that science for the first time.
