Research Interests
My research focuses on nonlinear analysis and partial
differential equations. I am particularly interested in the solvability of nonlinear second order parabolic and elliptic partial differential equations subject to nonlinear boundary conditions, and how these problems interrelate with physical and biological phenomena.
I am also interested in mathematical
epidemiology, im particular, developing and analyzing some delay differential equations models for infectious diseases.
