About Jens Ekengren

Jens is a senior lecturer in Mechanical Engineering and has been with Örebro university since 2013. He teaches courses in mechanics, strength of materials, materials engineering and technical analysis using FEA and CFD.

Research interests include, apart from those connected to his teaching, statistical evaluation of defects in steels (a question that has been nagging since the PhD project) and electrical, self-guided agricultural vehicles.
