After graduating from the L.N.GumilevEurasianNationalUniversity in Astana in 1998 I became an employee at the Institute of Mathematics of the Academy of Sciences. I worked at this Institute for six years. In 2004 I won a grant from the RoyalSwedishAcademy of Sciences for two years postgraduate study at Luleå University of Technology in Sweden. The result of this grant was the defense of my Ph.D. thesis entitled “A new development of Nikol’skii – Lizorkin and Hardy type inequalities with applications” in June 2006. In August 2006 I joined to KIMEP.
Function Spaces (embedding theorems, compactness of embeddings, Poincare type inequalities, etc.); Applications of Function Spaces to Differential Equations (boundary-value problems, a priori estimates, etc.); Weighted Inequalities with Applications (boundedness and compactness of Differential and Integral operators).
