About Me

I am a senior postdoctoral fellow at KU Leuven in the Department of Computer Science. I was previously a research fellow in Computer Science and Informatics at Liverpool John Moores University. Before that, I was a research associate at both TU Wien and the University of Oxford.

My academic interests lie in computational aspects of Algebraic Dynamical Systems and their applications in Verification and Program Analysis. My research advances scientific frontiers in the Theory of Computation through the design and analysis of algorithms.
