Sebastian Baunsgaard

Sebastian Baunsgaard is a PhD student at TU Berlin supervised by Matthias Boehm. His research focus is exploiting data structures in programs via workload-aware compression. Sebastian is a frequent contributor to open source code and is a PMC member in Apache SystemDS with contributions ranging from high-level compilation techniques to low-level tight-loop optimization of kernels. Sebastian received his bachelor and master from ITU Copenhagen specializing in advanced computing and algorithms. His dissertation is on the subject of speech recognition. Before starting his PhD, Sebastian worked with automatic test setup and installation of high-end cameras in Phase One, and full-stack web development in Zen Data Aps.
