Kevin Joseph Costello is an Irish mathematician, currently the Krembil William Rowan Hamilton Chair of Theoretical Physics at the Perimeter Institute for Theoretical Physics. He is renowned for his profound contributions to mathematical physics, particularly in the areas of quantum field theory, string theory, and the mathematical structures underpinning them. His work often involves sophisticated techniques from algebraic geometry, homological algebra, and category theory to address fundamental problems in physics. He is particularly known for his work on the renormalization of quantum field theories and the development of the theory of factorization algebras (with Owen Gwilliam), which provides a powerful framework for understanding observables in quantum field theory.
Kevin Joseph Costello's work history includes a series of influential roles in various companies. Here is a detailed list of his professional journey:
Awarded the 2017 New Horizons in Mathematics Prize for his profound contributions to mathematical physics, specifically for his work on the mathematical foundations of quantum field theory.
Co-developed (with Owen Gwilliam) the theory of factorization algebras, providing a rigorous mathematical framework for perturbative quantum field theory and its renormalization. This work culminated in their influential book 'Factorization Algebras in Quantum Field Theory'.
Made significant contributions related to topological string theory and integrable systems, including connections between Chern-Simons theory and the Korteveg-de Vries (KdV) hierarchy, often referred to as Costello-Witten theory.
Appointed as the Krembil William Rowan Hamilton Chair of Theoretical Physics at the Perimeter Institute, recognizing his leading role in the field.
Held a professorship at Northwestern University, where he mentored numerous students and postdoctoral researchers, significantly influencing the next generation of mathematical physicists.
