Julian was a PhD student at IPVS. He had worked on B-splines since his bachelor’s thesis, which was about spline approximation of scattered data using quasi-interpolation with B-splines. His master’s thesis treated gradient-based optimization using different types of hierarchical basis functions on sparse grids, one of which were B-splines. His PhD thesis with the title “B-Splines on Sparse Grids: Algorithms and Applications to Higher-Dimensional Optimization” continued this work, but focused solely on B-splines. During his time as a PhD student, he developed a profound “B-spline mania” (which is yet to be diagnosed by a doctor), keeping claiming that “B-splines are the best basis functions of the world” and propagandizing their alleged superiority at any given opportunity.
