From the nomination letters

"This is an exemplary dissertation. Its outstanding technical content is matched by an exceptionally clear-minded and successful effort at developing the additional depth, perspective, and clarity that make dissertations irreplaceable statements of scholarship, instead of binders for conference papers."

“[this dissertation] is much more than the “sum of its parts” – it is a significant advance over the underlying papers published about this work, laying out all the pieces in a coherent and thoughtful way.”

The technical work is clever, creative, and elegant; the limitations and indebtedness to prior work are generously discussed, the narrative offers remarkably lucid explanations of the minutest technical detail at a resolution that conference papers cannot match.

The awards were announced Tuesday, October 29, 2019 at the SOSP 2019 banquet and awards session in Huntsville, Ontario, Canada
