Leon Weber-genzel is a Machine Learning Research Engineer with over a decade of experience building ML models, evaluation pipelines and application software—especially in NLP and biomedical information extraction. He holds a summa cum laude Doctor of Science in Computer Science and has published at top venues (ACL, EMNLP, NeurIPS, ISMB) while turning research into state-of-the-art tools used in real workflows. At Humboldt and LMU he led projects on representation learning, novelty detection and bio-NER, and now applies that research pragmatically at smedo GmbH. A significant open-source contributor to the widely used flairNLP framework, he integrated multiple biomedical corpora and improved multi-tagger and performance-critical components. Motivated by creating software that directly improves people’s lives, he brings a rare blend of rigorous academic research, production-focused engineering, and hands-on dataset craftsmanship.
