Homepage of Per-Olov Åsén

I now work at COMSOL (but I still check the email-address above).
I completed my PhD in 2007 at the department of numerical analysis and computing science (Nada) at the royal institute of technology (KTH), Stockholm, Sweden.
Dissertation was May 25th 2007 and my supervisor was Gunilla Kreiss.

Teaching

No, not now.
