Paul Kiefer

Dr. Paul Kiefer is a Researcher at the Department of Mathematics, University of Antwerp, under the supervision of Prof. Ignacio Barros. His research focuses on modular forms, theta lifts, and their applications to number theory and geometry. He is affiliated with the SFB/TR 358 'Integral Structures in Geometry and Representation Theory' at Bielefeld University, contributing to projects on lattices, theta lifts, and hyper-Kähler varieties.

Recent research activities include organizing the conference 'Modular in Bielefeld' (June 2025), serving as a tutorial assistant for the Theta Summer School (July 2025), and presenting at the Siegel-Weil Summer School (September 2025). His work bridges algebraic geometry and analytic number theory, with a focus on automorphic forms and their arithmetic implications.

Key publications explore Eisenstein series, Borcherds products, and Poisson summation formulas. Kiefer's articles often intersect harmonic analysis, L-functions, and spectral theory, reflecting his interdisciplinary approach to modern number theory challenges.
