Jeff Jewell

Biographical Sketch

Jeff Jewell received his Ph.D. in Astrophysics from the University of Chicago in 2000. He was an NRC Post-Doc at JPL from 2000-2001, and in 2001 became a member of the Senior Level Staff in Information Systems and Computer Science. His research interests are in Bayesian inference for large data sets, inverse problems, dynamical systems, and spatial random fields.
