Short presentation

I am a PhD student in Scientific Computing since 2011. My main interests are in efficient implementations of finite-element methods for modern processors such as GPUs, and in development of scientific software. My advisors are Jarmo Rantakokko, Gunilla Kreiss, and Sverker Holmgren.

Keywords: finite element methods gpu matrix-free methods

My courses


I develop matrix-free finite-element methods for graphics processors. Matrix-free methods are superior to classical sparse-matrix-based methods for elements of order higher than one. I am an active developer of the open-source finite-element library deal.II, and my methods are in the process of being included in the official code base.
