#### Finite Element Exterior Calculus

Recently, theoretical tools from differential geometry have been incorporated in the development of finite element methods. The resulting framework, known as finite element exterior calculus (FEEC), enables design and analysis of finite element methods such that certain topological and geometric structures of partial differential equations are preserved. In particular, we are interested in using FEEC to develop structure-preserving finite element methods for mixed formulations of partial differential equations (e.g., Stokes equations).#### Efficient discretizations of fractional differential equations

I am developing and analyzing efficient numerical methods for solving fractional differential equations (FDEs). FDEs are nonlocal integro-differential equations for which traditional approximation techniques require significant computational complexity, hence new approaches are needed. These types of equations arise in models of complex materials, anomalous transport, ultrasound, and other applications involving nonlocality and memory effects.#### Boundary conditions for fractional diffusion operators

As FDEs involve nonlocal operators, the concept of boundary conditions must be reinterpreted in this context. I am currently working on developing numerical methods for dealing with nonlocal reflecting boundary conditions in anomalous diffusion problems.# Presentations and Posters
