Per Olof Arnäs has been working in, around, and with the logistics industry since the late 1980s, both as a professional and as a researcher. He holds a PhD in logistics from Chalmers University of Technology (where he now is a researcher) and has also worked as a developer building sustainability tracking systems for the freight industry. His main focus of research is the digitalization of the industry, both how it can be accelerated and also the effects/implications of it. Apart from his research he is a podcaster.
