2012- Senior Development Engineer, Special Advisor (Technical director of McStas)
at the DTU Physics
Major projects
Simulation package for investigating parameter significance in
tomographic imaging - for my masters thesis
d3view - 3D visualisation package for brain images -
developed for Neurobiology Research
Unit. The 'Viden
om' TV show on science has had two features
about brain imaging and brain
surgery once available in REAL video format in which d3view is
used for visualisation. Also used for front cover illustrations in
Neuroimage
