Andreas Bang Leed
Head of Data Science, Oxford Global Projects · PhD Fellow in Economics, Aarhus University
I measure what others leave to guesswork, from the cost and risk of large infrastructure projects to the price of nature. I lead the data science team at Oxford Global Projects, and my doctoral research in economics puts defensible numbers on questions that appraisals usually leave out.
