Rich Lehoucq's home page
My research interests include 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, structural dynamics and radiation transport.

My current research focuses on multiscale mechanical methods. My interest is in understanding the link between atomistic and continuum representations of physical phenomena. In particular, I'm interested in the multiscale aspects of Stewart Silling's peridynamics, a nonlocal continuum theory. See Peridynamics for multiscale materials modeling for a recent review of peridynamics.

I am an associate editor at ETNA (Electronic transactions on numerical analysis) and SINUM (SIAM Journal on Numerical Analysis), and a member of the editorial board of the International Journal of Computational Science and Engineering.
