Keith Still is what I term an intuitive mathematician. He is one of the most creative and original thinkers that I know. He adds drive and determination, as well as considerable intellectual power to any group of which he is a part…….His intuition for subtle patterns of behaviour in complex data is impressive, the best I've ever seen." Prof. Ian Stewart - Fellow of the Royal Society.

Professor Still has lectured at the UK Cabinet Office Emergency Planning College since 1999 and developed the EPC’s Crowd Dynamics and Crowd Science materials and workshops as well as contributing to several other safety-related courses. 

His mathematical, human behaviour modelling and simulation tools led to the development of a systematic blueprint for the crowd safety industry. He has developed educational workshops teaching the theory and applications of Crowd Science, applied it to major events around the world. His tools (Legion, Paramics UAF, Myriad - click here for link to current modelling tools) have been used for the analysis of crowds in complex and built spaces for over a decade.

Keith was made a Fellow of the Institute of Mathematics and its Applications (FIMA) in late 2007 and is the G4S Professor of Crowd Science at Buckinghamshire New University, near London. In August 2012 Keith was made a fellow of the Institute of Civil Protection and Emergency Management (FICPEM) and in May 2014 he was made a Specialist Fellow of the International Institute of Risk and Safety Management (SFIIRSM).
