David Rydh

David Rydh is a Professor at the Department of Mathematics, Royal Institute of Technology (KTH), specializing in algebraic geometry. His research focuses on algebraic stacks, moduli problems, birational geometry, blow-ups, and derived algebraic geometry.

Recent research includes Mayer–Vietoris squares, Artin algebraization for stacks, and canonical stabilizer reduction for good moduli spaces. His work intersects with topics like non-reductive geometric invariant theory, valuation theory, and motivic homotopy.

Current projects include participation in the Mittag-Leffler program on Moduli and algebraic cycles and organizing workshops on Motives and Hodge theory and Moduli spaces and log geometry.

He has supervised several PhD students, including Jeroen Hekking, Eric Ahlqvist, and Daniel Bergh, and Master’s students such as Axel Sarlin and Fabian Carlström.
