 ===== Biography =====
-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-current). 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.

-===== Wigner-specific research =====
+===== Wigner Motivation =====
+The  Wigner  function  resembles  many  concepts and  notions  of the
+classical  statistical  mechanics.   The  analogy with  the classical
+distribution  function becomes even  closer if  a particle  picture is
+associated to the Wigner  formalism.  General quantum phenomena may be
+modeled  in  terms of  quasi-particles  involving  attributes such as
+drift, generation, sign, and annihilation on a phase space grid. These
+concepts  provide  both,  a  heuristic picture  of  quantum evolution
+numerical  feasibility  of  the  developed Monte  Carlo  method. The
+particle  model  is examined  in  an  ultimate  regime of  a constant
+electric   force,  where   classical  and   quantum   dynamics become
+equivalent.  It is  interesting to see how the  usual Newtonian motion
+in the momentum space of an  initial peak of particles is resembled by
+processes  of annihilation  and generation  of  quasi-particles, which
+reside on  a momentum  grid and  can not gain  or lose  momentum. The
+first applications to carrier transport in multidimensional structures
+are  already  a  fact  showing  promising  practical  aspects  of the
+approach.
+The  strong formal  similarity between the Wigner generation and annihilation of signed particles and
+the physical  processes of absorption  and emission of phonons  by the
+lattice motivates  the  extension of the approach to phonon transport.
