Summary
🤩
Rockstar🎓
Top SchoolMarcel Wever is a research group leader and applied machine learning researcher with nine years of experience bridging academic rigor and practical AutoML engineering. He holds a summa cum laude PhD in Computer Science from Paderborn University and has held research and coordination roles at institutions including L3S, Leibniz Universität Hannover, LMU Munich, and the Munich Center for Machine Learning. Marcel contributes to open-source AutoML tooling—notably integrating the MLPlan framework with WEKA and scikit-learn in the widely used OpenML automlbenchmark—bringing deep expertise in pipeline encoding, metric support, and prediction runtime analysis. He combines hands-on implementation skills with academic leadership, managing education programs and research projects that translate complex model selection problems into reproducible benchmarks. Based in Paderborn, Germany, he is comfortable operating at the intersection of software engineering, empirical evaluation, and ML systems research. An attention to detail in encoding and column handling underscores his focus on reliable, production-ready ML workflows.
