Jannek Squar got his B.Sc. in Computing in Science with focus on physics and obtained his M.Sc. in Computer Science at Universität Hamburg. As a student he worked for several years as a teaching assistant in various fields like “Formal Foundations of Computer Science” and “Algorithms and Data Structures”. Since November 2016 he has been employed as a scientific researcher at the working group Scientific Computing for the project “i_SSS - integrated Support System for Sustainability”. His research interests include intra-node and inter-node parallelism and high performance computing in general.
