Donald Lupo studied chemistry at Davidson College in North Carolina, USA and gained his Ph.D. in physical chemistry at Indiana University. Subsequently he worked as a post-doctoral fellow in the Laboratory for Physical Chemistry at the ETH in Zürich, Switzerland. He reinvented himself as a materials scientist after taking up a position in central research at Hoechst AG in Frankfurt am Main, Germany in 1986, where he worked in nonlinear optics based on Langmuir-Blodgett films, polymer OLEDs and solid state dye sensitised solar cells (DSSC). At Sony International (Europe) GmbH he built up the Materials Science Laboratory in Fellbach, Germany and continued his work on polymer OLEDs and organic solar cells. At NTera Ltd. in Dublin, Ireland he was head of display R&D for paper-like displays based on electrochromic nanomaterials. He then spent 8 years as a technology consultant working on mass printed electronics, roll to roll printable displays and dye solar cells with companies such as UPM Kymmene, Merck and G24 Innovations. In August 2010 he accepted a professorship in electronic materials in the Department of Electronics and Communications Engineering, at Tampere University of Technology. There he is head of the Laboratory for Future Electronics responsible for activities in electronics materials and manufacturing, with interests in printed diodes, transistors and solar cells and in the effect of printing processes on materials, interfaces and devices.
