Overview
I joined COMSYS in April 2022 after completing my Bachelor’s and Master’s degree in Computer Science at RWTH Aachen University.
Research
As a member of our Cyber-Physical Systems group, my research interests include resilience and precision of sensor networks. My current focus lies in the area of smart home and home monitoring, with the goal to find reasonable compromises between intrusiveness, reliability, accuracy, efficiency, simplicity, (monetary) cost and maintenance overhead of the setup(s). Research projects of mine typically involve sensor setups, sensor networking and data collection, (pre-)processing, analysis and interpretation. If you are interested in working with me or writing a thesis, please contact me via E-mail.
