 Mihail Nedjalkov, born in Sofia, Bulgaria received a master'​s degree in semiconductor physics at the Sofia University "Kl. Ohridski",​ a PhD degree (1990), habilitation (2001) and D.Sc. degree (2011) at the Bulgarian Academy of Sciences (BAS). He is Associate Professor at the Institute of Information and Communication Technologies,​ BAS, and has held visiting research positions at the University of Modena (1994), University of Frankfurt (1998), Arizona State University (2004) and mainly at the Institute for Microelectronics,​ Technische Universität Wien. Nedjalkov has been supported by the following European and Austrian projects: EC Project NANOTCAD (2000-03), Österreichische Forschungsgemeinschaft MOEL 239 and 173 (2007-08), FWF (Austrian Science Fund) P-13333-TEC (1998-99) START (2005-06), and P21685 '​Wigner-Boltzmann Particle Simulations'​ (2009-2014). He has served as a lecturer at the 2004 International School of Physics '​Enrico Fermi',​ Varenna, Italy. He is a member of the Italian Physical Society, APS and AMS reviewer. His research interests include physics and modeling of classical and quantum carrier transport in semiconductor materials, devices and nanostructures,​ collective phenomena, theory and application of stochastic methods. ​ Mihail Nedjalkov, born in Sofia, Bulgaria received a master'​s degree in semiconductor physics at the Sofia University "Kl.
