I graduated from Brown University with an Sc.B. in computer science in 1987, and got an M.S. and Ph.D. from UC Berkeley in computer science in 1990 and 1995, respectively. I was part of the RAID group at Berkeley, where I did my dissertation work on using randomized data placement for high-performance file systems, a project that laid some of the foundation for later work on the Ceph file system.

In 1994, I accepted my first faculty position at the University of Maryland, Baltimore County, where I remained until 2000. I then moved to the University of California, Santa Cruz, where I helped found the Storage Systems Research Center in 2001. I founded the Center for Research in Storage Systems in 2012, which I directed for eight years, stepping down in 2019. At UCSC, I have held the Veritas (originally Symantec) Presidential Chair in Storage Systems for seven years.


I live in Santa Cruz with my wife Lisa and our family. Sabrina graduated from Tufts and is now working in Seattle for Microsoft. Zachary is at UC Santa Barbara, and Zoe is in high school. Our family and two dogs, Lilah and Fozzie Bear, keep us busy.
