Welcome to my webpage!

About me:

  • I am currently a tenure track assistant professor at Department of Mathematical Sciences, at UTEP.
  • Till Fall 2014, I was a post doctoral fellow in the working group Mathematical Methods of Simulation headed by Prof. Guido Kanschat , University of Heidelberg, Heidelberg, Germany.

  • In December 2011, I completed my Ph.D. from the University of Houston, Houston Texas under the guidance of Prof. Ronald Hoppe.
  • Prior to my time in Houston, I obtained my Bachelors and Masters in Mathematics from the University of Delhi, New Delhi, India.
  • Research Interests:

  • a posteriori error analysis for partial differential equations discretized through Galerkin methods.
  • exploring new applications of finite exterior calculus.
  • Analysis of non linear partial differential equations specifically p-Biharmonic, p-Laplacian problems.
