Appointments • August 2014 – present Assistant Professor, University of Texas at El Paso, El Paso. • August 2012 –August 2014 Postdoctoral Fellow IWR, University of Heidelberg, Heidelberg. • January 2012 –July 2012 Postdoctoral Fellow University of Houston, Houston, Texas. External Funding • NSF DMS 1520862: Collaborative Research: Numerical Simulation of the Morphosynthesis of Polycrystalline Biominerals, 2015-2018; PI (with PI at participating institute Ronald Hoppe, University of Houston). Research • Research Interests My research interests are a posteriori error analysis for partial differential equations discretized through Galerkin methods, developing efficient adaptive schemes and robust iterative methods to solve time dependent and stationary differential equations. My long term research goals are to apply the finite exterior calculus tools to nonlinear pdes and to investigate an adaptive electromagnetic field propagation in heterogeneous media where adaptivity is also driven by the material discontinuities. • Publications – Guido Kanschat and Natasha Sharma, Divergence-conforming Discontinuous Galerkin Methods and C0 Interior Penalty Methods.
