Biography

Materials scientist and solid-state chemist with a PhD, over 30 years of research and teaching experience. My expertise spans solid-state reactions, nanostructured oxide materials, thermal decomposition mechanisms, and precursor-based synthesis strategies. I have extensive experience as a Senior Researcher at SB RAS and as an Associate Professor at Novosibirsk State University, where I also developed and taught advanced courses in solid-state chemistry and materials science. A significant part of my research has been dedicated to understanding how mechanical phenomena and structural transformations influence morphology and reaction kinetics. My team and I developed a classification of feedback mechanisms and built quantitative models to describe these interactions. We proposed a predictive approach for controlling the size and shape of nanocrystals produced during precursor thermolysis. Using this method, we successfully synthesized nanocrystalline oxides of iron, nickel, manganese, tin, cerium, zirconium, copper, yttrium, and various lanthanides through the thermolysis of oxalates, achieving precise control over product texture. We also studied the mechanisms of porosity formation and the development of diverse morphologies during metal oxide reduction. The resulting insights were applied to optimize iron oxide catalysts for CO₂ Fischer–Tropsch synthesis, develop porous anodes and electrolytes for solid oxide fuel cells (SOFCs).
