Joan's Research

Your guide to my academic and professional journey in science, technology, and beyond.

About My Journey So Far

Curiosity has always been the driver of my scientific adventure, with coding and computers as key tools to accomplish my projects. Participating in the Youth and Science program by Fundació Catalunya La Pedrera has been one of the most transformative experiences in my journey. It opened doors to the world of research and allowed me to gain first-hand experience in a professional research environment.

For as long as I can remember, I've been fascinated by the biggest, most energetic, and exotic phenomena in the Universe. My interest in cosmology stems from this curiosity to understand how the Universe works on the largest scales. I've focused on measuring the Hubble–Lemaître constant H₀ — the expansion rate of the Universe — whose exact value is still unknown. I began in 2023 by recomputing H₀ using Cepheid luminosity data, and in 2024 I used Type Ia Supernovae (Ia SNe) for this purpose during a research stay at the ICE-CSIC-IEEC under the guidance of Dr. Lluís Galbany.

In summer 2025, I completed my Youth and Science scholarship with a research stay at the Osservatorio Astronomico di Brera-Merate (INAF-OAB). There, I focused on the study of Gamma-ray Bursts (GRBs) as cosmological probes, extending our capabilities to observe the high-redshift Universe in the search for constraints on cosmological parameters.

Outside "the office," I love to share my enthusiasm for science with others by volunteering in science outreach activities, such as the CosmoCaixa Explainers by CosmoCaixa. Additionally, I graduated in May 2025 with a 1.0/1.0 Abitur and 13.334/14 Selectividad (German and Spanish high school diplomas) from the German School of Barcelona, along with a distinction in physics from the Deutsche Physikalische Gesellschaft.
