Ph.D.   In Mathematics (  1995 ) - University of Illinois at Urbana-Champaign, IL ,USA

Research Interests:  Dynamical Systems, Control Theory and Optimal Control of Partial Differential Equations.

My primary work is on finding the Maximum Number of Limit Cycles of Certain Polynomial Lienard Systems in relation to the Second Part of Hilbert’s 16th Problem.  Another interest is on how to close the gap between necessary conditions and sufficient conditions for Optimal Control Solutions of nonlinear systems in relation to the Pontryagin Maximum Principle. I am also interested in Optimal Control of Partial Differential Equations.

Teaching: I have been teaching a wide range of courses ranging from College Algebra, Trigonometry, Pre-Calculus , Calculus, Deductive Mathematics, Discrete Mathematics, Statistics, Modern Algebra,  Introduction to number Theory, Advanced Calculus, Real Analysis , Vector Analysis , Introduction to Topology, Differential Equations, and Introduction to Control Theory to Introduction  Linear Algebra.
