Dr. Lucius Fekonja
Lucius Fekonja studied Knowledge Visualization at the Art Academies in Lucerne and Zurich and worked in earlier projects on neurosurgical and evolutionary biological topics.
He received his doctorate from Charité - Universitätsmedizin Berlin on the topic of diffusion MRI based dissection of fiber bundles in tumor patients.
His research in the project Cutting is dedicated to the analysis and representation of the brain’s white matter based on MRI data. This is achieved in particular by tractography, which also centrally guides image-based surgical planning.
Lucius' analyses and visualizations translate the activity of functional networks. He is therefore interested in how images represent complex knowledge and how they acquire their own instructive character. The studies and prototypes that are created in this work process move in the field of tension between analog drawing and digital modelling.
