Alexander Belov is Head of Thermal Modeling Group at “OPTOGaN. New Technologies of Light Ltd.” of Skolkovo Center of Innovations in Moscow and also senior staff scientist at Theory Department of the Institute of Crystallography (Ph.D. 1987 Russian Academy of Sciences, Moscow). He was awarded by research fellowship of the Soros Foundation (1993) and distinguished postdoctoral fellowship of the Max Planck Society (1995). His previous academic appointments include the Max Planck Institute of Microstructure Physics (1995-1999, Halle, Germany), Helmholtz-Zentrum Dresden-Rossendorf (1999-2003, Dresden, Germany), and Dresden University of Technology (2003-2008, Dresden, Germany). His reserch interests evolved from continuum mechanics (continuum theory of dislocations and fracture mechanics) to multiscale materials modeling, including molecular dynamics computer simulations and first-principles quantum mechanical calculations of defects in solids. Current research focuses on semiconductor nanowire heterostructures and defects in GaN light emitting diods.
