Professor Alejandro Ramirez Rojas did his undergraduate studies at the Faculty of Sciences of the Universidad Nacional Autónoma de México (UNAM), obtained his master's degree in Physics at the School of Physics and Mathematics of the Instituto Politécnico Nacional (IPN) and obtained his doctorate at the Faculty of Sciences of the Autonomous University of the State of Mexico with a specialty in Nonlinear Physics and time analysis of complex systems.

Since 1985, he has been a professor and researcher at the Universidad Autónoma Metropolitana (UAM) in Mexico City, attached to the Research Area of Physics of Irreversible Processes of the Department of Basic Sciences. He teaches physics and mathematics courses in engineering and graduate courses. He has been a thesis advisor at the undergraduate and Ph.D. levels and collaboration with a postdoctoral fellow.

He has made short stays at the International Center for Theoretical Physics (ICTP) in Trieste Italy and during the last 6 years at the Istituto di Metodology per l'Analisi Ambientale-Consiglio Nazionale delle Rcherche (IMAA-CNR) in Italy.

His field of research is nonlinear dynamics applied to various physical problems with emphasis on time series analysis for the study of complex systems such as tectonic dynamics in subduction zones, as well as experimental in the analysis of synthetic seismicity.

He has participated in publications focused on soft matter issues. So far, he has published about 40 articles in indexed journals and about ten as first author, five book chapters, and one scientific book. He has been responsible for theoretical and experimental projects at the University and also for bilateral projects with CNR of Italy. He has participated as a referee for indexed scientific journals such as Entropy, EPL, Physyca A, NHESS, Pure and Applied Geophysics, among others. He is a member of the national system of researchers of CONACyT (Level II) in Mexico, a regular member of the Mexican Academy of Sciences and the European Geosciences Union (EGU).
