I'm Professor at the Department of Computer Science, Electrical and Space Engineering performing research on electromagnetic modeling. In this area, we have been working with developing the Partial Element Equivalent Circuit (PEEC) method since 1999. Our main academic partner is University of L'Aquila (IT). We have performed a multitude of projects in the areas of:

  • power systems,
  • antenna systems,
  • device modeling etc.

For futher information on my work, please browse through the publications below, look at the presentation (here), and contact me for further discussions.

Since 2009, I am acting as Head of the Department often referred to as Prefect. This means that I am responsible for all activities, centres, and development associated to the Department.
