At the moment, I´m working both as a part time PhD Student at LTU (50%) and as a Technical Steel-specialist at Trafikverket – The Swedish Transport Administration (50%). I have been working with steel- and composite structures during the last 10 years, mainly focused on bridges. I have spent seven years as a bridge designer and the last years as a steel specialist on the client side. Today, my research is focused on composite bridges in general and the steel parts in particular. During the time period 2016-2018, I will work part time at LTU with main focus on the European R&D-project Prolife (Prolonging life time of old steel and concrete-steel bridges), which is coordinated by LTU.
