Background
Priv-Doz Dr-Ing Dipl-Inform Jörn Mehnen has a background in machining technology (PhD) and soft computing (MSc) from TU Dortmund, Germany. He studied computer science and mathematics and took his PhD in manufacturing.
In 1995 he began his research career at the Department of Machining Technology (ISF) at the University of Dortmund, Germany. There he obtained his PhD (Dr-Ing) and received admittance for teaching (venia legendi, Habilitation) in 2005 as a Privatdozent (Priv-Doz).
In 2007 he joined Cranfield University as a Senior Lecturer within the Manufacturing Department. He is also still Privatdozent (Priv-Doz) at TU Dortmund (Germany).
