Panagiotis E. Keivanidis was born in Pireas, Greece in 1976. In the period of 1995 – 2000 he studied Chemistry at the Chemistry Department of University of Crete in Heraklion, Greece. In 1998 he completed his practical work in the industrial sector (SaniCot SA, Pireas) and in 2000 he completed his Diploma Thesis in the Luminescence Group of Prof. A. Meijerink, at the University of Utrecht, the Netherlands. In 2001 he worked as a lab assistant in the Sol-Gel Lab of the Institute of Materials Science, at the National Centre for Scientific Research ‘Demokritos’ in Athens, Greece. In 2005 he received his PhD (magna cum laude) in Natural Sciences (doctor rerum naturalium) from Johannes Gutenberg University of Mainz in Germany for his studies on the electronic energy transfer processes in π-conjugated polymers, in the Solid State Chemistry Group of Prof. G. Wegner at the Max Planck Institute for Polymer Research (MPI-P). In the period of 2005 – 2008 he was a Research Associate in the Optoelectronics Group of Prof. Sir R. H. Friend in the Cavendish Laboratory at Cambridge, UK where he performed research on the development of low dark-current solution-processed organic photodetectors and on the study of perylene diimide derivatives as functional n-type materials in organic photodiodes and solar cells. In the period of 2008 – 2010 he was a Research Associate in the Group of Experimental Solid State Physics in the Blackett Laboratory at Imperial College London working with Prof. J. Nelson and Prof. D. D. C. Bradley. During his staying in London he performed transient absorption and delayed luminescence spectroscopic experiments (in the μs - ms time range), for correlating the efficiency of charge photogeneration and recombination in organic photovoltaic composites with their layer microstructure. In the period 2010 - 2014 he held a team leader position by establishing the Device Technology & Chemical Physics Group at the CNST@PoliMi of the Italian Institute of Technology (IIT).

His research interests include the electro-optical characterization of solution processable power-generating and photo-detecting devices and the optimization of device functionality through structure-property-performance correlations.
