Kort presentation
Mitt forskningsområde är experimentell kärnfysik och studier av strukturen hos atomkärnor som har ett underskott eller överskott av neutroner jämfört med de naturligt förekommande isotoperna för varje element. För närvarande är forskningen fokuserad på studier av neutronfattiga kärnor i massområdet omkring den dubbelmagiska kärnan 100Sn med 50 protoner och 50 neutroner.
