Areas of Research

My current research interests include topics in Supersymmetric Quantum Mechanics, Shape Invariance, Quantum Hamilton-Jacobi formalism, Exactly Solvable and Quasi-exactly Solvable problems in Quantum Mechanics, Historical research in Black-Body radiation, and Physics Education. Currently, there are several undergraduate students working with me and contributing greatly to my research projects.


In recent years, I have contributed to the following two areas:
a) My collaborators and I have shown that all shape invariant systems have an underlying algebraic structure (equivalent to the shape invariance condition) that guarantees their solvability (1,2); and
b) we have derived an infinite set of differential equations that are equivalent to the shape-invariance condition – a difference-differential equation. Solving these equations, we showed that the list of all conventional solvable was indeed complete (3,4,5).
