Biography

My research and development interests center around two major topics. The first is discretizations of PDEs for unstructured grids such as; finite element, finite volume and discontinuous Galerkin methods. The second topic is modeling and simulation fluid flows such as; incompressible, compressible, turbulent, reacting, wave propagation and MHD.

Education

Received a B.S. in Aerospace Engineering from the Pennsylvania State University,
M.S. in Aerospace Engineering from Georgia Institute of Technology,
PhD in Aerospace Engineering from Georgia Institute of Technology.
Thesis: "Unsteady Simulations of Turbulent Premixed Reacting Flows"
