Ragnar E. Löfstedt (born 1964) is an academic variously described as Swedish and American. Since 2002, he is the Professor and Director of King's Centre for Risk Management, King's College London. He is an author of several Risk books especially on risk communication.
Löfstedt has been appointed by the UK Coalition Government to look at occupational safety and health and in particular, the bureaucracy faced by those self-employed whose work activities do not pose a risk to others.
Until 2002 Löfstedt was reader at the Centre for Environmental Strategy, University of Surrey where he worked with Berkeley academic David Vogel. Their paper was published in the Journal of Risk Management.
