Iris van der Giessen is a Research Fellow in the UKRI project "Structure vs. Invariants in Proofs" under supervision of Anupam Das. Van der Giessen obtained her PhD at the Utrecht University, the Netherlands, under supervision of Rosalie Iemhoff and Nick Bezhanishvili with her thesis titled "Uniform Interpolation and Admissible Rules. Proof-theoretic investigations into (intuitionistic) modal logics".

Her research focuses on structural proof theory, cyclic proof theory and (intuitionistic) modal logic. Her interests also include proofs-as-programs, proof-theoretic semantics, and ecumenical systems. She investigates interpolation properties (i.e. Craig, uniform, …) of logics from a proof-theoretic point of view and by using semantic reasoning. She aims to bridge the proof-theoretic research to applications in computer science.
