Biography

Bill is in the final stages of his PhD at Stony Brook University where his research focuses on file systems and storage. He is part of the team that made BetrFS, a Linux file system built using write-optimized dictionaries.

Bill is also a member of the transdisciplinary art collective Talk is Cheap: Unincorporated Language Laboratories and a silkscreen printmaker in Mobile Print Power. Both groups use art to engage communities in issues of social justice.

Research

Bill is involved in ongoing projects at all levels of the storage stack. At the block layer, he is working on a software translation layer for host-managed shingled magnetic recording drives. At the file system layer, he is working to improve and stabalize the BetrFS file system. At the application layer, he is exploring new query models that bring to reads the same benefits that write-optimization brings to writes.
