Claas Fischer Section Tower, Foundation, Rotor Blade
TÜV NORD SysTec GmbH & Co. KG

I studied naval architecture at the Hamburg University of Technology (TUHH) from Fall 2003 until March 2010 and focused on structural analysis. After my graduation, I was with the Institute of Ship Structural Design and Analysis at TUHH as a research assistant and doctoral candidate, performing experiments and numerical analysis with respect to ultimate strength of propeller blades and fatigue estimation of welded joints. Beside this, I participated in commissions of the International Institute of Welding regarding fatigue. My doctoral thesis deals with the review of an energy-based approaches used for the fatigue assessment of welded joints. Since 2016, I am an expert at TÜV NORD for the evaluation of steel towers.
