We are a collaboration of mathematicians and historians from the Universities of York and York St John, with interests spanning 20th century international and military history, operations research and warfare analysis. Current collaborative research topics include the Battle of the Atlantic, the dynamics of insurgency, US use of survey data in Vietnam, the game theory of nuclear deterrence (including the 1983 Able Archer scare), and inter-war gaming, especially of naval aviation.

Changepoint Analysis of Historical Battle Deaths (arXiv:1909.02626 [stat.AP]) introduces an algorithm built from the latest techniques for finding changes in time series of heavy-tailed data and uses it to find the moments at which the historical pattern of war deaths changed significantly.

Bootstrapping the Battle of Britain introduces weighted bootstrapping, the statistical technique of weighted resampling with replacement, as a tool for exploring alternative histories, and is in the January 2020 edition of theJournal of Military History.

Dr Ian Horwood
is a historian at York St John University. His principal interests are in US military history, airpower history, and the wars in Indochina.

Professor Niall MacKay
is a mathematician and theoretical physicist at the University of York. He has interests in military history, operations research and combat modelling.

Dr Christopher Price
is a historian at York St John University. His main areas of interest are financial, economic and military history in the twentieth century, especially the inter-war period.

Dr Jamie Wood
is a mathematician and systems biologist at the University of York. He specializes in the simulation and analysis of complex systems, and has interests across a range of modern international history and the analysis of warfare.


We offer PhD projects across our full range of interests, for historians and mathematicians. The only additional qualification needed is sympathy with the other discipline and an interest in the techniques it can bring to the project. If you're interested, get in touch!
