Reserach

My main research interest are in EDA tools for processor and accelerator design. I am currently developing a tool called NoGAP.

Upplysning Lecture Series

Upplysning is a lecture series arranged by the Lysator academic computer society. I've been invited to give one lecture to date.

Teaching

I have been involved in some way in almost all courses that we have. The following is a list of courses where I have been involved as more than a teaching assistant/lab assistant:

• TSEA26: Design of embedded DSP processors Course development
• TSEA44: Computer hardware - a computer system on a chip (2004-2008, course development), lecturer
