Welcome! I'm Ludvig Olsen

I'm an R and python developer with an MSc in Cognitive Science, working as a PhD student at the Department of Molecular Medicine (MOMA) at Aarhus University Hospital. Current projects revolve around detection and localization of cancers from cell-free DNA in blood samples.

I worked with deep learning on text at UNSILO and medical imaging data at Cercare Medical.

The aim of my career is to have a very big positive impact on this world of ours! 🌍
