Background and activities

I am senior engineer at the Section for Applied Physics, NTNU IFY. My primary task is to provide assistance in experimental work such as optical measurement, data acquisition, programming, thin film deposition and other types of research based activities.

I have strong skills in instrumentation and programming languages such as Python, C, Matlab, Fortran. Furthermore, I have experience in quasi-optical experiments and microwave design techniques.

I am electronics engineer from the Technical University of Denmark (DTU). After I received my masters degree I was employed in a telecommunication company as an  RF engineer. In my next job I worked with plasma diagnostics at Risø National Laboratory, Denmark. I was awarded a PhD degree at Risø and afterwards a post doc at the University of Chalmers working on active and passive microwave integrated circuit design and simulations.
