After post graduation in pure mathematics, he worked at IIT-B. First at Microwave Remote Sensing Lab of Center for Studies in Resource Engineering (from May 1999 to February 2000), for Indian Space Research Organization - IIT-B sponsored project of ``SAR Interferometry and Earth Crust Movement'' under the guidance of Dr. K. S. Rao. Then he worked at Industrial Mathematics Group of Department of Mathematics, for Department of Science and Technology sponsored project of ``Doing Industrial Mathematics via Genetic Algorithms, Differential Algebraic Equations, Online Optimization, Computer Aided Geometric Design and Market Forecasting'' (from March 2000 to August 2001) with Prof. A. K. Pani.
In September 2001, he joined University of Twente, The Netherlands, for Ph. D.. There he studied at Applied Analysis and Mathematical Physics group of Department of Applied Mathematics, and was affiliated with MESA+ Research Institute. With prof. dr. E. van Groesen as the promotor, and dr. Manfred Hammer as the supervisor, he did his research on the European Commission funded project ``Next generation Active Integrated optic Subsystems'' (NAIS). In August 2003, he finished his post graduation in mathematical sciences, and in October 2005, he finished his doctoral studies.
