Sebastian Boblest studied physics at the University of Stuttgart and earned his PhD in Theoretical Physics. He then worked as a postdoctoral researcher at the Institute for Visualization and Interactive Systems at the University of Stuttgart.

His research interests were visualization in special and general relativity, as well as the visualization of flow simulations on supercomputers. He now works with Robert Bosch GmbH, Reutlingen, in the field of embedded artificial intelligence.
