I've worked on a myriad of projects over the course of my career. These include

  • analysis of the peridynanmic nonlocal continuum theory, including mechanical and mathematical analyses.
  • nonlocal diffusion equation
  • directed graphs and their statistical analyses
  • the numerical solution of large-scale eigenvalue problems and differential equations. I am a co-author of ARPACK and Anasazi, open source software for computing eigenvalues of large-scale matrices. I have collaborated with scientists to use ARPACK in applications in Quantum physics, CFD, spectral graph theory, structural dynamics and radiation transport.
