I have been working with steel- and composite structures during the last 13 years, spending 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.
Research interest
- Steel- and composite bridges
- Composite bridges with prefabricated deck elements
- Steel fatigue
- Shear connections in composite structures
- Integral abutment bridges
- Strengthening of steel- and composite bridges
- Development of codes and standards for steel- and composite structures
Professional expertise
- Design of steel- and composite structures
- Assessment of steel- and composite structures
- Prefabrication of bridges
- Steel fatigue
- Execution standars for steel structures
- Finite element modelling
