The Lawrence fellowship is the most prestigious post-doctoral fellowship offered by the national labs. Lots of resources and complete freedom for three years to work on anything you want.

The final competition is gruelling and it requires giving a lecture to physicists and other creatures, personal interviews, etc. It is extremely unusual for a computer scientist to win this award. Greg's work focuses on fault tolerance techniques for high-performance computers, making it very applicable to Livermore, the home of the world's largest supercomputers. His application was facilitated by Bronis de Supinski from Livermore and Sally McKee from CSL, who has also mentored him. Greg works with CS Professor Keshav Pingali.
