Biography

Harriet Åhlgren received her doctorate in Physics from the University of Helsinki Finland in 2015, two years after finishing her MSc in Physics. Her studies concentrated on ion irradiation response of graphene and were carried out under the supervision of Dr. Jani Kotakoski. She is currently a postdoctoral research fellow at the University of Nottingham UK in the group of Professor Elena Besley (August 2015-present).

Current Research Project

"Modifying and functionalizing 2D nanomaterials with ion irradiation" funded by the Young Scientist Scholarship from Emil Aaltonen foundation. Modeling electron beam induced dynamics in graphene.
