Maximilian Böther

Hey, nice to meet you! 👋

I am pursuing a Ph.D. in Computer Science at ETH Zurich Systems Group and the Efficient Architectures and Systems Lab (EASL), supervised by Ana Klimovic and Gustavo Alonso. My interests include data management for machine learning, machine learning pipelines and deployments, and data selection techniques.

I am currently working on Mixtera (Github), a lightweight data plane for LLM/VLM training, and on Modyn (Github), a platform for training machine learning models on datasets that grow over time. In all projects, we emphasize the importance of data for machine learning, and explore how we can build systems supporting data-centric ML.

I obtained B.Sc. and M.Sc. degrees in IT-Systems Engineering from Hasso Plattner Institute, Potsdam, Germany in 2020 and 2022. I published several papers at renowned venues, e.g., SIGMOD, VLDB, MLSys, and ICLR, have received a Best Paper Award at GECCO’21, and interned at Google on the CoreML team. Please find my CV here.
