G. Keith Still lectured at the UK Cabinet Office Emergency Planning College (EPC) from 1999 - 2013 contributing to a wide range of crowd safety related courses and teaches short courses around the world.

His tools (Legion, Paramics UAF, Myriad, Dwell AnalysisProgressive Crowd Collapse and Tawaf models - click here for a link to the modelling projects page) have been used for the analysis of crowds in complex and built spaces for ove two decades. Although he has developed and used some of the most sophisticated crowd modelling and simulation tools, his work remains true to the core principles of his original research. As stated in Chapter 2 of his PhD The objective of this research is to develop standards for crowd safety.

Keith was made a Fellow of the Institute of Mathematics and its Applications (FIMA) in late 2007. In August 2012 Keith was made a fellow of the Institute of Civil Protection and Emergency Management (FICPEM).  In March 2014 a Specialist Fellow of the Institute of Risk and Safety Management (SFIIRSM). In August 2015 he became a member of the Expert Witness Institute (MEWI) and in December 2015 Keith became a Fellow of the Institute of Place Management (FIPM). In June 2017 Keith became a Fellow of the Higher Education Academy (FHEA).
