I retired from active service at UC Santa Cruz on July 1, 2023. Please read this blog post for details. Since I am an emeritus faculty member, I don't have regular teaching duties or service duties. My plan is to continue my research collaborations with colleagues, including those in the Storage Systems Research Center. I don't plan to take on any new students as a primary advisor. However, I will consider co-advising students who want to study in specific research areas: secure file systems and data storage, archival storage and operating systems for non-volatile memories. If you have an interest in either of these areas and an outstanding strong background in computer systems, I'd be happy to consider co-advising you in a Ph.D. in those areas.

I'm the Director Emeritus of the NSF I/UCRC Center for Research in Storage Systems (CRSS) and the Associate Director of the Storage Systems Research Center here at UC Santa Cruz, where I explore issues in file and storage systems and, more generally, distributed systems and operating systems. My current projects include file systems for next-generation storage technologies, archival storage systems, file system security, scalable file system indexing, and exascale storage systems. I'm also interested in storage system benchmarks, algorithms to more efficiently manage storage, and information retrieval from very large text and multimedia corpora as well as other problems in computer systems and security.

Research interests

My research has focused on storage systems, with a focus on security, archival storage, and large-scale storage. I have also done significant research in operating systems and distributed systems.

File systems & storage

Secure storage

I have been exploring secure storage for over twenty years, starting with my work on lockbox storage, published in FAST 2002.

Archival storage

Stuff about archival storage.

Flash storage

Stuff about flash storage, including Pure Storage.

Scalable storage

Stuff about scalable storage, including Ceph.

Operating systems

Recently, I’ve been investigating operating systems for single-level stores that restructure how the operating system interacts with non-volatile storage: the Twizzler project.
