I develop accurate, robust and efficient numerical methods and turn them into high-quality software for research and operational use. Since my PhD, my main arena has been flow in porous media. Open source has been my strategy for close to 20 years, with reproducibility and open innovation as the goals. I set research direction, mentor younger researchers and build strong research groups. My current interest is how agentic AI is changing research and software development.
