History

I came to RPI in Fall 2002.  In May 2007 I obtained my Ph.D.  from the Department of Computer Science
with concentration in Computational Science. Since then I have moved back to India and am currently working at Siemens PLM, Pune .

Academic Experience

    Thesis: A new stability method for singularly perturbed convection-diffusion equations.
   Advisor: Professor Emeritus Joseph E. Flaherty
  
   Proposed a new approach for solving singularly perturbed convection-diffusion problems in the finite
   element framework. This involved the modification of the test function spaces resulting in a Petrov-Galerkin
   method. The test function space was chosen to provide a good approximation to the solution of a suitable dual
   problem. Because of the presence of multiple scales in the dual solution, asymptotic methods were used to compute
   an approximation to the dual solution. Also proposed an error estimation  strategy for these problems in the
   proposed finite element  framework.

Research Interests

     My interests are very broad and some of the topics that interest me are:

• Machine Learning (http://videolectures.net/andrew_ng/)
  
• Mathematical modeling, Numerical Methods
• Data Structures & Algorithms, C++ Programming, STL
  
• Problems which require an interdisciplinary approach

       My interests can be broadly termed as using mathematics, computers to solve problems in engineering and science.
