Andreas Bang Leed, Head of Data Science at Oxford Global Projects

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. One strand examines how estimation noise and project selection produce systematic cost overruns in public projects. Another puts a price on nature, estimating how the ecological quality of nearby nature is reflected in Danish house prices.

My advisory work has taken me to more than 25 countries, collaborating with governments, multilateral organisations and leading consultancies on projects ranging from nuclear energy and transport to space exploration and artificial intelligence.

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

Selected impact

A few examples of where the work has changed decisions.

UK transport appraisal. I authored analysis for the UK Department for Transport that informed appraisal guidance shaping how billions of pounds of public investment are assessed.

Hong Kong early warning. I helped build the Project Supervision System, an AI early-warning system that monitors Hong Kong's public-works portfolio and flags projects drifting toward cost overrun or delay, early enough to act.

Global advisory. I have advised governments, multilateral organisations and consultancies across six continents, on projects from nuclear energy and transport to renewable power, artificial intelligence, and biodiversity.

What drives my work

The projects I work on are among the largest investments a society ever makes, whether a railway, a hospital, a power station or a motorway. Each one shapes how people live for decades and reshapes the land, water and wildlife around it for far longer. The same investment can pay back many times over or waste vast public sums, and when it goes badly the natural world, which is rarely counted in the accounts, tends to lose the most.

That is what drives me. Big investments and the environment are the same problem, which is how to make large decisions under deep uncertainty where you have to put a number on something instead of guessing at it. The methods are technical but the reasons for caring about them are not. Better evidence means less public money wasted on major projects and more of the living world left standing. That is where my research increasingly points, towards giving biodiversity the weight that these decisions have almost always denied it.

I'm always keen to connect with organisations and individuals who share a passion for evidence-based decision making.
