Andreas Bang Leed

Head of Data Science & PhD Fellow

I lead the data science team at Oxford Global Projects, where we develop evidence-based tools and analytical solutions to help organisations make better decisions on complex, high-stakes projects. Our work draws on the world's largest database of project performance, spanning thousands of projects across dozens of countries and sectors.

I am also a PhD Fellow in Economics at Aarhus University, where my research focuses on econometrics and the economics of large-scale infrastructure and environmental policy. My current work examines how estimation noise and competitive selection produce systematic cost overruns in public projects.

My advisory work has taken me across continents, collaborating with governments, multilateral organisations and leading consultancies on projects ranging from nuclear energy and transport to renewable power and artificial intelligence.

I am co-author of How to Measure Anything in Project Management (Wiley, 2025), a #1 bestseller. I regularly speak at international conferences and teach a master's-level course on cost-benefit analysis in the public sector at Aarhus University.
