Doctor Guillermo Chacón Acosta (CDMX, 1981) is a Mexican research professor. He studied from undergraduate to a doctorate at the Universidad Autónoma Metropolitana (UAM). During his master's degree, he stayed at the Federal University of Paraná with Professor Gilberto Kremer, and during his doctorate at the University of Mainz and the Pennsylvania State University.

He has specialized in the study of the in- and out-of-equilibrium statistical physics of various systems, particularly relativistic high-temperature gases. He has also worked on applying these tools to quantum systems for the study of the phenomenology of quantum gravity and recently on social processes such as model economies and option price variation. Currently, he has started to work on the study of diffusion theory in confined systems, curved surfaces, and networks, being of interest the mathematics behind pattern formation.

He has 51 scientific articles and four collective book editions. He has presented about 130 papers, from specialized international forums to scientific dissemination talks. He has supervised ten theses at all levels, from undergraduate to doctoral. He has organized around ten national and international events. He has been a referee in several scientific journals and has been part of several evaluation committees. From 2015-2017 he was a member of the board of directors of the Division of Gravitation and Mathematical Physics of the Mexican Society of Physics, and from 2015 to 2018, he was the Coordinator of the Graduate Program in Natural Sciences and Engineering at the Universidad Autónoma Metropolitana (UAM).

He has been a National System of Researchers member since 2013 and currently holds the Level I distinction.
