Senior🎓
Top SchoolWillem Klumpenhouwer is a transportation data scientist and principal consultant with nine years of experience turning complex urban mobility problems into clear, evidence-driven policy and operational insights. He holds a PhD in Transportation Engineering and an Honours BSc in Theoretical Physics, combining rigorous mathematical modelling with practical experience in rail operations and transit planning. Willem leads end-to-end analytics projects—research design, data wrangling, geospatial analysis, visualization, and web development—to help planners and policymakers make better-funded, better-communicated decisions. He has applied machine learning to railway delay analysis, built custom internal data tools for government use, and worked inside rail operations as a qualified Rail Traffic Controller, giving him a rare blend of frontline operational understanding and analytic depth. A practiced communicator, he has translated technical work for public audiences via media appearances and expert panels, and runs Klumpentown Consulting to scale that impact. Based in Calgary, he focuses on pragmatic, reproducible analysis that advances more reliable and equitable urban transit.
