I’m a research associate and 4th year PhD student at TU Berlin, working in the research group on Distributed and Operating Systems (DOS) by Prof. Odej Kao. Before that, I’ve worked as a Software and Data Engineer at different companies in Berlin. My research focus is on carbon-aware computing: Aligning the power consumption of computing systems with the availability of renewable energy. Besides that, I’m interested in research on systems for machine learning as well as the co-simulation of computing and energy systems.
