Ulrich Drepper joined Red Hat again in 2017, after a seven year hiatus when he worked for Goldmann Sachs. He is part of the office of the CTO and concentrates on developing new technologies for high-performance computing (and machine learning specifically), mostly in collaboration with university groups. In his last position at Goldman Sachs he focused on the development of models and various types of stochastic algorithms to aid in operation of the technology for the entire firm. He also taught internally various classes around machine learning and other computing topics. Additionally, Ulrich was internally a consultant for all aspects related to performance, low latency, and C/C++ compilers.
His previous stint at Red Hat lasted 14 years. The last position was as member of the office of the CTO to collect and disseminate information relevant to the Red Hat Enterprise Linux product, predominently in the high-performs area. His main interests are in the areas of low-level technologies like machine and processor architectures, programming language, compilers, high-performance and low-latency computing. In addition he is interested in using statistics and machine learning for performance analysis of programs and security of application and OS environments.
