Research Interests:
My broad field of research is nonlinear differential equations.
Recently my work is focussed on dynamical
systems governed by nonlinear fractional differential and
differential  difference equations. The study of fractional
differential equations (FDEs) has been handicapped due to the
absence of well defined analytic techniques to deal with them
in general and deriving their solution in particular.
In my work, considerable efforts have been made to devise techniques
to derive certain interesting mathematical aspects including
solution of FDEs. My recent work extends the following analytic methods to FDEs :
 Lie Symmetry Analysis
 Invariant Subspace Method
 Homotopy Analysis Method
 Adomian Decomposition Method
