Professor Shane D. Johnson has worked within the fields of criminology and forensic psychology for over fifteen years. He has particular interests in exploring how methods from other disciplines (e.g. complexity science) can inform understanding of crime and security issues, and the extent to which theories developed to explain everyday crimes can explain more extreme events such as riots, maritime piracy, and insurgency. He has published over ninety peer-reviewed papers and book chapters and his work has been covered in The Economist, New Scientist, and by the UK press.
