Konstantin Lübeck is a graduate research assistant at the Chair for Embedded Systems of the University of Tübingen. He received B.Sc. and M.Sc. degrees in Computer Science from the University of Tübingen in 2015 and 2018 respectively with a major focus on computer engineering and embedded systems. In 2016, he studied at the Uppsala University as an Erasmus exchange student. In 2017, he received a scholarship for master’s thesis from the Stiftung Industrieforschung. Since 2018, he is a lecturer of computer architecture for the Bosch Learning Company initiative at the technology transfer center Tübingen. In addition to his academic work, he is a trained mechatronics technician (certified by the German chamber of industry and commerce, IHK) and worked as a self-employed software developer.

Research Interests

Modeling, evaluation, and prediction of machine learning accelerator performance (end-to-end latency, throughput, roofline) using analytical models based on computer architecture descriptions (from register-transfer level to abstract block diagrams) and deep neural network parameters (layer types and their hyperparameters) for fast design space explorations used in neural network-hardware co-design algorithms.
