Research
My main interest is interface evolution (multiphase) problems and calculus of variations, but I am also open to any interesting problems in numerical analysis and scientific computing (theory and/or applications) — not limited to my research interests. Feel free to contact me for possible thesis topics and/or collaboration.
“I like crossing the imaginary boundaries people set up between different fields — it’s very refreshing. There are lots of tools, and you don’t know which one would work. It’s about being optimistic and trying to connect things.”
