Diego García-Sepúlveda is a theoretical physicist whose research investigates the fundamental principles that organize quantum field theory, a unifying framework for a wide range of physical phenomena. His work has focused on non-invertible symmetries, anyon condensation, and the topological and categorical structures underlying quantum field theory, aiming to clarify how deep categorical and algebraic frameworks give rise to physical phenomena. He is currently a Junior Fellow in the Harvard Society of Fellows, working within the Departments of Physics of Harvard University and participates actively in the broader theoretical-physics community of Cambridge. Diego earned his Ph.D. in Physics at the University of Chicago, under the supervision of Prof. Clay Córdova, where he worked on several aspects of generalized symmetries in strongly coupled gauge theories. Prior to his doctoral studies, he obtained a B.Sc. in Physics from the University of Chile (Chile), and a dual M.Sc. through UNESP (Brazil) and the Perimeter Scholars International program in charge of University of Waterloo along with Perimeter Institute for Theoretical Physics (Canada). The work of García-Sepúlveda has been recognized a number of times. In 2017, he achieved first place in the Premio IFT-ICTP para Jovens Físicos (IFT-UNESP / ICTP-SAIFR), an award recognizing the most promising young physicists in Latin America. At University of Chicago, he later received the Bloomenthal Fellowship (2023) for outstanding achievement in theoretical physics. Diego’s research seeks to understand how generalized symmetries extend and refine the conventional notion of symmetry in field theory, particularly in lower-dimensional gauge systems. His recent work explores how these structures govern phase transitions and dualities, including level–rank dualities, and particle spectra in two-dimensional quantum chromodynamics. Driven by an enduring curiosity about symmetry, duality, and topology, he seeks to reveal the organizing principles that structure quantum field theory.
