Rockstar🎓
Top SchoolStéphan Tulkens is a Principal Machine Learning Engineer based in Antwerp with 11 years of experience building ML systems that bridge research and product. He holds a PhD in Computational Linguistics and has shipped applied models across startups and scale-ups—from semantic vector models and compact embeddings at The Minish Lab to production ML work at Metamaze, Dataprovider and Slimmer AI. Currently at Ecosia he combines model-building with an environmental mission, and as cofounder of The Minish Lab he’s produced practical research artifacts like Model2Vec and Semhash. His background in software engineering and cognitive models of reading gives him an unusually strong grasp of both low-level systems and human-centered language modeling.
