Welcome. I am a postdoctoral researcher in the Computational Methods in Systems and Control Theory Group at the Max Planck Institute for Dynamics of Complex Technical Systems, led by Prof. Peter Benner. Previously, I was a research associate in the Numerical Linear Algebra Group at The University of Manchester, where I also completed my PhD in June 2022 under the supervision of Prof. Nicholas J. Higham.

My research is largely concerned with the design, analysis, and development of algorithms in Numerical Linear Algebra. I studied the computation of Matrix Functions in arbitrary precision arithmetic during my PhD, and a part of my recent research has focused on Mixed-Precision Techniques.

I am currently a participant in the research project:

Matrix Functions and Exponential Integrators, funded by the DFG Scientific Networks programme, 2025.
