Notă biografică
Professsor Felix Sharipov graduated from the Moscow University of Physics and Technology, Faculty of Aerophysics and Space Research, and the Ural State Technical University. Since 1988 he is active in rarefied gas dynamics, since 1992 at the Federal University of Parana in Brazil. His research interests are numerical methods of rarefied gas dynamics applied to microfluidics, vacuum technology and aerothermodynamics. His group develops both probabilistic and deterministic approaches. Prof. Sharipov was organizer of numerous vacuum gas dynamics meetings, and published over a hundred journal articles, conference papers, and book chapters. He is a member of editorial board of international journal ?Vacuum?
