Biography

I am the manager for the Scientific Machine Learning department in the Center for Computing Research at Sandia National Laboratories. I joined Sandia National Laboratories in 1992 as a student intern from the University of New Mexico. After receiving my B.S. from UNM in 1993, I joined the Computational Sciences department at Sandia as a software engineer developing high-performance computing software for molecular visualization, data clustering, parallel acoustic wave propagation, and seismic imaging. In 1997, I left Sandia to attend graduate school at Dartmouth College, where I received a Ph.D. in Computer Science in May, 2003. Later that year, I returned to Sandia to join the Scalable System Software department. Since joining Sandia I have either contributed, led, or managed research projects in systems software, parallel file systems, scalable I/O libraries and middleware, resilience, performance modeling, advanced architectures, scalable visualization, and machine learning.

Education

  • Ph.D., Computer Science, Dartmouth College, 2003
  • B.S., Computer Science, University of New Mexico, 1993
