I have been working with steel- and composite structures during the last 13 years, mainly with a focus on bridges. I have spent the first seven years as a bridge designer and the last years as a steel specialist on the client side. My research is focused on composite bridges in general and the steel parts in particular. At the moment, I´m employed as a Technical Steel-specialist at Trafikverket – The Swedish Transport Administration and part time as a reseracher at LTU.
