Kevin Franz Stehle, M.Sc.

Kevin Franz Stehle is a PhD student at the Computing Systems Group at the Institute of Computer Engineering at Heidelberg University. His thesis encompasses the research of time-series anomaly detection using machine learning, with a focus on deep learning methods, and the evaluation of the efficiency of currently used detection methods.

Kevin earned his Bachelor’s degree in Mechatronics Engineering at Ulm University of Applied Sciences in 2017. He subsequently enrolled as a Master’s student in Computer Engineering at Heidelberg University, graduating in 2020. He then joined the ATLAS Experiment at CERN as a PhD student funded by a German Federal Ministry of Education and Research Wolfgang Gentner Scholarship, with Heidelberg University as his host university, and Prof. Dr. Holger Fröning as his advisor. At ATLAS, he started his work of developing a practicable anomaly detection method for the ATLAS High-Level Trigger cluster that forms part of the data acquisition and processing pipeline of the experiment. After the end of the scholarship in 2023, he joined the Computing Systems Group, where the work on High-Level Trigger anomaly detection continues, and is now expanded by the investigation of the computational and memory intensity/efficiency of contemporary anomaly detection approaches, with the ultimate goal of not only expanding possible application settings for deep anomaly detection.
