Biography

I’m interested in numerical methods for PDEs, and their efficient implementation on current and future HPC architectures. My background is in applied mathematics, including PDEs, functional analysis, numerical analysis, and HPC. I am also interested in modern software design and testing, with the goal to enhance code readability, maintainability, and extensibility.
