Briefly about me and my research: During the end of my MSc in Mechanical Engineering with specialisation in machine design, I had the opportunity to write my master’s thesis at the division of Machine Elements, where I dived into the interesting field of tribology. Here, I continued as a PhD student in a project related to crankshaft roller bearings under supervision of Professor Roland Larsson, where my main focus is simulation of elastohydrodynamic lubrication (EHL) under transient loading conditions.

Specialities: Machine elements; Tribology; Numerical simulations; Product development; Computer-aided design; Programming.
