Dr. Guillermo Chacón-Acosta is a Mexican physicist and research professor born in Mexico City in 1981. He completed his undergraduate, Master's, and doctoral studies at the Universidad Autónoma Metropolitana (UAM). During his Master's program, he conducted a research stay at the Federal University of Paraná in Brazil working with Professor Gilberto Kremer, while during his doctoral studies he completed research stays at Johannes Gutenberg University Mainz in Germany and The Pennsylvania State University in the United States. In 2022, he carried out a sabbatical research stay at the University of Potsdam in Germany with Professors Ralf Metzler and Aleksei Chechkin, followed by a research stay at the University of Barcelona in Spain with Professor Miguel Rubi.

His research focuses on equilibrium and nonequilibrium statistical physics applied to diverse physical systems, with particular emphasis on high-temperature relativistic gases. He has applied these methods to quantum systems, exploring quantum-gravity phenomenology, as well as to social and economic processes, including model economies and option price dynamics. His current research interests encompass diffusion processes in confined systems, curved surfaces, and complex networks, focusing on the mathematical mechanisms underlying pattern formation.

He is the author of over 50 scientific articles, co-editor of four books, and has presented approximately 130 contributions at international scientific conferences, specialized research meetings, and outreach events. He has supervised ten undergraduate, Master's, and doctoral theses and organized about ten national and international scientific events, notably including the long-running Winter Meeting on Statistical Physics. He has served as a peer reviewer for several scientific journals and as a member of various academic evaluation committees.

In administrative and professional service, he served on the Board of Directors of the Division of Gravitation and Mathematical Physics of the Mexican Physical Society (2015–2017) and as Coordinator of the Graduate Program in Natural Sciences and Engineering at UAM Cuajimalpa (2015–2018). He is currently a member of the Editorial Board for the Complex Systems Section of the Revista Mexicana de Física for the 2026–2028 term. He has been a member of Mexico's National System of Researchers (SNII) since 2013, currently holding Level II status for the 2024–2028 term.
