​My research focus is in partial differential equations and development of numerical methods for their approximate solving. I have published papers in the areas of numerical methods, partial differential equations, gas dynamics, nonlinear analysis, secondary oil recovery, chain vibrations, etc. I presented my research at numerous conferences and seminars at the national and international level. I am very passionate about my teaching and I have taught various mathematics and statistics courses at all levels – from the developmental to graduate. At UHD I proposed and developed a course "Introduction to Topology and Functional Analysis". I have conducted over 20 undergraduate projects / senior projects / directed studies during my time at UHD.​​
