Academic research

I was in academia from 2012 to 2020, first as a doctoral student and then as a postdoctoral researcher at Linköping University. I worked in the Information Coding Group at the Department of Electrical Engineering under Prof. Jan-Åke Larsson, focusing on the security of quantum key distribution protocols.
