W. Knap obtained his master degree from Faculty of Physics – Warsaw University Poland and got a permanent assistant professor position at Experimental Solid State Physics Department . His PhD concerned the Terahertz (Far infrared) properties of narrow gap semiconductors HgTe and InSb. In 1987 he left to France and worked at University of Montpellier, Grenoble High Magnetic Field Laboratory, Toulouse Pulsed High Magnetic Field Laboratory. Between 1999 and 2001 he worked at– Rensselaer Polytechnic Institute USA. He obtained also a long term grant from Japan Society of Promotion of Science and spent a year at Tohoku University 2007-2008. He currently leads International Research Agenda -CENTERA at IHPP- Polish Academy of Sciences. His main scientific interests are : i) Fair Infrared-FIR (Terahertz – THz) properties of semiconductors, ii) Quantum phenomena in transport and iii)Terahertz Plasma excitations in nanostructures. He published more then 400 papers and his H factor is > 50. He is 2022 laureate of ERC advanced grant on THZ plasmonics.
