    Dr. Larissa Levina has a Masters Degree in Organic Chemistry from the Chemistry Department of the Kazakh State University and holds a Ph.D. in Organic Catalysis and Electrochemistry from the Institute of Organic Catalysis and Electrochemistry, Almaty, Kazakhstan. During her employment as a Senior Researcher at the Laboratory of Homogeneous Catalysis of the Institute of Organic Catalysis and Electrochemistry in Almaty, Kazakhstan, Dr. Levina has investigated the kinetics of the oxidation hydrogen sulfide by ozone in presence of halogen anions and Cerium halogenides. She has also developed novel liquid-gas phase method of cleaning industrial gases from hydrogen sulfide, hydrogen phosphide, and hydrogen arsenide in the presence of homogeneous catalysts. Presently Dr. Levina is working on the synthesis of novel nanomaterials.

    Dr. Oleksandr Voznyy earned his Ph.D. in physics of semiconductors from Chernivtsi National University, Ukraine for his work on electronic properties of nitride semiconductor alloys. In 2005 he joined the Quantum Semiconductors and Bionanophotonics lab at University of Sherbrooke as a postdoc, working on theoretical modeling of laser-assisted quantum well intermixing and self-assembly processes of organic monolayers on metal and semiconductor surfaces for applications in bio-sensing. In 2008 he moved to Quantum Theory Group at National Research Council of Canada in Ottawa, where he worked on many-body problems in epitaxial and colloidal semiconductor and graphene quantum dots; in particular, simulations of multi-exciton generation, Auger processes and optical properties of nanocrystals used in hybrid polymer-semiconductor solar cells. Oleksandr joined Ted Sargent's group in 2011 and is currently working on characterization and modeling of the semiconductor nanocrystal surfaces and developing the synthesis methods for nanomaterials with improved optical and transport properties for photovoltaics.
