Kort præsentation

My research revolves around the formation and evolution of the building blocks of the Universe we live in. This is best described as the ‘Life cycle of cosmic matter’, which includes the elemental ingredients synthesised in massive stars. When the stars explode as supernovae, the elements are released and become available for the formation of molecules and solid particles, so called ‘cosmic dust’. While I am interested in the physical processes which govern the evolution of dust, stars and galaxies, I pay particular attention to the different types of supernovae, their progenitors and their post-explosion evolution.
