Research interests

My research interest lie in the field Inverse and Ill-Posed problems, which is very active and rapidly developing area of of Mathematical Physics. The focus of my current research is to study inverse and ill posed boundary value problems for new no classic system differential equations with partial derivatives using some modern methods of mathematic analysis, mathematical physics and numerical mathematics.
