Research Interests

I am interested in a wide range of topics related to infrastructure for building software systems, including development frameworks, programming languages, operating systems, and storage systems. My primary current project is RAMCloud, a new approach to storage where all information is kept in DRAM and large-scale storage systems are created by aggregating the memories of thousands of servers.


I received a BS in Physics from Yale University in 1975 and a PhD in Computer Science from Carnegie Mellon University in 1980.

From 1980-1994 I was a Professor of Computer Science at the University of California, Berkeley. My research projects included design tools for integrated circuits such as the Magic layout editor and the Crystal timing analyzer, the Sprite network operating system, log-structured file systems, the Tcl scripting language, and the Tk toolkit.

In 1994 I left Berkeley to fulfill a long-standing desire to build commercial software. From 1994-1998 I was a Distinguished Engineer at Sun Microsystems Laboratories. In 1998 I founded Scriptics Corporation to commercialize Tcl development tools, where I was CEO until 2000. In 2002 I founded Electric Cloud. I was at Electric Cloud until 2007, and I led the development of a parallel build system (ElectricAccelerator) and a Web-based server for managing distributed processes such as nightly builds and automated tests (ElectricCommander).

In 2008 I returned to academia in the Department of Computer Science at Stanford.
