About me

I am currently working as a Ph.D. student, and my research focuses on strengthening techniques for existing steel-concrete bridges, particularly I-girder bridges with concrete decks, both with and without composite action. My study revolves around two main subjects: achieving box-action for steel I-girder composite bridges through implementing lateral bracing and exploring partial composite action in bridges.

I hold a Master of Science in Civil Engineering from LTU. During my master's thesis in 2015-2016, which I completed at Ramboll Sweden, I thoroughly investigated a strengthening technique for composite steel I-girder bridges. This involved increasing torsional stiffness to reduce sensitivity to fatigue stresses from eccentric loads.

In addition to my academic pursuits, I have worked as a consultant for Ramboll's bridge department in Luleå, specializing in steel and composite bridges. My responsibilities included system analysis and detailed designs for both steel and steel-concrete composite bridges. Furthermore, I had the opportunity to contribute to a European R&D project titled "Prolonging Life Time of Old Steel and Steel-concrete Bridges" where we developed and investigated various strengthening techniques for existing bridges.

Research interests

Anything within the field of steel bridges, but certainly strengthening and development of new- and existing methods for strengthening and design.

My objectives are to

• develop methods to strengthen existing bridges
• provide solutions to prolong the lifetime of steel and steel-concrete bridges
• engage in work that brings joy to myself and others

Professional expertise

• Design of steel and composite bridges
• Strengthening of steel- and composite bridges
• Finite element modelling
• Development and interpretation of standards for steel structures
