Biography

I am a Senior Member of Technical Staff in the Scalable System Software department of the Center for Computing Research (CCR). I research system software for next-generation extreme-scale systems. Specifically, I study the impact of system failures, and other sources of performance interference, on the execution of scientific simulations. I am also investigating application performance in power-constrained environments. I earned my Ph.D. from the University of New Mexico, where I worked with Prof. Patrick Bridges in the Scalable Systems Lab. At Sandia, I work with Kurt Ferreira, Patrick Widener and the 9lives research group on improving the resilience and fault tolerance of large-scale parallel systems.
