Department of Information Technology

Since 2011, I am a PhD student Scientific Computing, and my advisors are Jarmo Rantakokko, Gunilla Kreiss, and Sverker Holmgren.


My research aims at developing efficient implementations of multiphase-flow simulations using heterogeneous computer systems. My main interest is in general-purpose graphics processing units (GPGPUs).
