My work includes the development of high-quality open-source scientific software:

• Trilinos
  
  
  • Description: The Trilinos Project is an effort to develop algorithms and enabling technologies within an object-oriented software framework for the solution of large-scale, complex multi-physics engineering and scientific problems. A unique design feature of Trilinos is its focus on packages.

    Lead Developer of Intrepid
    Intrepid is a Trilinos (Sandia National Labs) library of PDE discretization tools, enabling an element-level mix-and-match approach to implementing compatible and high-order finite element, finite volume, and mimetic finite difference methods for the solution of a variety of PDEs.

    Lead Developer of Aristos
    Aristos is a Trilinos (Sandia National Labs) package for nonlinear nonconvex optimization, based on sequential quadratic programming (SQP) methods. Aristos is specifically designed for the solution of large-scale constrained optimization problems in which the linearized constraint equations require iterative (i.e. inexact) linear solver techniques. Aristos' unique features are the efficient control of inexactness in linear system solves and the scalable solution of NLPs with a very large number (billions) of optimization variables.
    
    Availability: Fall 2010.
