Johan Iraeus

Researcher at Vehicle Safety

Johan’s research is focused on biomechanics, with emphasis on car crashes. The research is mainly carried out using computer simulations with human body models, but also includes database studies. A field of specialization is population based simulations, i.e. how system changes influence a population. The goal is to be able to predict the effect of new countermeasures in terms of saved lives/reduced harm, before the system is on the market. Johan defended his PhD thesis in 2015 and before that he worked for more than ten years with computer aided vehicle development, primarily crashworthiness.
