Short biography
Born in 1964. Masters equivalent University Degree in Physics (1987) from St. Petersburg State University. Ph.D. equivalent degree in Polymer Physics (1994) from the Institute of Macromolecular Compounds, Russian Academy of Sciences with an award for young scientists from the authority of St. Petersburg in 1995. In 1996, invited to the International Solvay Institutes of Physics and Chemistry in Brussels to work on irreversibility and dissipation in quantum systems including the decoherence problem with potential application to quantum information. In January 2005, joined the Centre for Quantum Information and Communication as a postdoctoral fellow.
