Dr. Keith Still has always been a mathematician, and he has always enjoyed music. It was while standing in a queue for a rock concert 20 years ago that these two interests collided to produce one of those classic ‘lightbulb’ moments. In that moment his thinking crystallised and a new branch of applied science was born - his PhD (Crowd Dynamics) has had over 60,000 downloads since publication (available on this site). Since that moment he has focussed on his academic and professional career on understanding and developing crowd sciences. He is now considered the world expert in his chosen field and his initial interest in crowd sciences has developed into a lifelong passion for public safety. At the same time the global appetite for large scale public events has grown, making the crowd sciences (modelling sites, behaviour, movement, developing crowd management plans) indispensable to the events, sports and entertainment world.
