My main area of research is qualitative theory of linear/nonlinear differential equations. I have worked on fuzzy differential equations, set differential equations and functional differential equations. Recently, I have been studying some fundamental aspects of the functional differential equations with anticipation and retardation (FDEAR). These FDEAR are an important class of differential equations that have applications to signal analysis, biology and social sciences.
I am also interested in Wavelet Analysis and its applications to boundary value problems and to image processing problems.
Image inpainting, Phase Unwrapping for Synthetic Aperture Radar, and Radar image processing are some of the industrial applications that I study using the theory of differential equations and wavelet analysis.
I have the following joint patent aprroved by the United States Patent and Trademark Office (USPTO):
