- | Ognyan Oreshkov received his M.S. in Theoretical and Mathematical Physics from Sofia University, Bulgaria, in 2002. He then moved to Los Angeles to pursue doctoral studies in Physics at the University of Southern California, where he obtained his Ph.D. in 2008 under the supervision of Prof. Todd A. Brun. Following his graduation, he worked as a postdoctoral researcher at the Quantum Information Group at the Universitat Autònoma de Barcelona (2008-2009) and at the Quantum Foundations and Quantum Information Theory Group at the University of Vienna (2010). As of 2011, Ognyan is a member of QuIC, where he has been funded by a Marie Curie Intra-European Fellowship for Career Development, and an F.R.S.-FNRS Chargé de Recherches Fellowship. | + | Ognyan Oreshkov received his M.S. in Theoretical and Mathematical Physics from the University of Sofia, Bulgaria, in 2002.
