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, headed 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 (Sep 2018–Jun 2022) and was very fortunate to be supervised by Prof. Nicholas J. Higham.
Broadly speaking, I work in Numerical Analysis and Numerical Linear Algebra, focusing on the design, development, and analysis of numerical algorithms, with attention to mixed-precision computation. I am currently a participant in research projects on:
- Matrix Functions and Exponential Integrators, funded by the DFG Scientific Networks programme, 2025.
- Matrix Functions and Equations, led by Prof. Awad H. Al-Mohy and funded by King Khalid University (grant RGP.1/318/45), 2024.
