Gabriel S. Koch is a Senior Lecturer in Mathematics at the University of Sussex, within the School of Mathematical and Physical Sciences. He has been at Sussex since 2011, first as a Lecturer (2011-2016) and then promoted to Senior Lecturer (2016-present). His academic journey includes positions at the University of Zürich (2012), Oxford University (2009-2011), and the University of Chicago (2006-2009).
Dr. Koch's educational background includes:
- B.A. in Mathematics with honors (Magna Cum Laude) from Brandeis University (1996-1999)
- Ph.D. in Mathematics from the University of Minnesota (2000-2006), supervised by Vladimír Šverák
Professor Koch's research focuses on the analysis of nonlinear partial differential equations, with a particular emphasis on the Navier-Stokes equations that describe fluid motion. His work investigates regularity theory, singularity formation, and mathematical properties of these fundamental equations in fluid mechanics. He employs advanced techniques from mathematical analysis, including profile decomposition methods, harmonic analysis, and functional analysis in various function spaces. His research addresses one of mathematics' most challenging open problems - the regularity of solutions to the Navier-Stokes equations, which is a Clay Mathematics Institute Millennium Prize Problem.
The publication record shows a consistent focus on Navier-Stokes equations and related partial differential equations, with recent works examining partial regularity, blowup rates in Besov spaces, and parabolic fractal dimensions of singularities. His publications appear in prestigious journals including Acta Mathematica, Communications in Mathematical Physics, and Mathematische Annalen, with his 2009 paper in Acta Mathematica receiving over 240 citations.
Professor Koch has received research funding through an EPSRC 'First Grant' for his project 'Analysis of the Navier-Stokes regularity problem' (2015-2017), which supported both research and a workshop on the topic in September 2017. His collaborative work with researchers including Isabelle Gallagher, Fabrice Planchon, and Carlos Kenig demonstrates an international research network focused on advancing the mathematical theory of fluid dynamics.
His academic service includes mentoring students and maintaining an active research program addressing fundamental questions in mathematical fluid dynamics. Professor Koch's methodological approach combines techniques from harmonic analysis, functional analysis in critical spaces, and profile decomposition methods to investigate the deep mathematical properties of fluid flow equations.
