Senior🎓
Top SchoolKrzysztof Maziarz is a Principal Researcher at Microsoft Research in London with nine years of experience at the intersection of machine learning and drug discovery, teaching AI to do real science in collaboration with pharma partners. His work specializes in graph neural networks for generative chemistry, property prediction, and reaction planning, building on a strong theoretical CS background from Jagiellonian University. Previously he advanced large-scale model research during multiple influential internships at Google—coauthoring early work on sparse Mixture-of-Experts—and developed novel multi-view and AutoML approaches in industry and research roles. Comfortable moving between research and engineering, he combines deep theoretical grounding with practical skills in model design, architecture search, and production-facing systems. Colleagues describe him as someone who turns principled ideas into tools that accelerate real-world scientific discovery.
