Nick Vlachopoulos obtained a degree in chemical engineering from the National Technical University of Athens, Greece (1979), and two doctorates from the University of Pennsylvania, PA, USA (1984), and the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland (1990). He worked as researcher in the group of Professor Michael Grätzel at EPFL (1986–1999). In 1988-89 and in 2000-2014 he was employed in as researcher in France, Denmark, Germany, and Sweden in several areas of analytical and physical electrochemistry as well a research and development scientist in Ntera Ltd., Ireland in electrochromic devices. In 2014, he returned to EPFL as Senior Research Scientist and Lecturer in the group of Professor Anders Hagfeldt. His activities have been mainly related to the application of electrochemistry in energy conversion, with particular emphasis to molecular electrochemistry of chemically modified mesoscopic oxide electrodes and their application to solar energy.
