Dan Graham is Professor of Statistical Modelling in the Department of Civil and Environmental Engineering (DCE) at Imperial College London (ICL) and Head of the ICL Centre for Transport Studies. He is also Director of the ICL Transport Strategy Centre (TSC) and he leads the Transportation Data Science theme within DCE.
Dan holds doctoral degrees from the Department of Mathematics at Imperial and from the London School of Economics. He is a Project Partner of the Data Centric Engineering Program at the Alan Turing Institute, a Fellow of both the Institute of Mathematics and its Applications (FIMA) and of the Royal Statistical Society (FRSS), and a visiting Professor at South East University in Nanjing.
Dan's research group works on mathematical and statistical models with applications in transportation. Key research themes include: statistical modelling for performance analytics; causal inference methods and applications; data centric engineering; mathematical modelling in economics, operations and planning; wider economic impacts; and resilience, risk and safety analyses. Dan has published extensively in these fields and he holds citation records for a number of his papers.
In addition to his academic roles, Dan provides public policy advice internationally and has served as Specialist Advisor to the UK Parliamentary Select Committee on Transport.
