Sanjay Ghemawat
Google Fellow

I have been working at Google since late 1999 on distributed systems, performance tools, indexing systems, compression schemes, memory management, data representation languages, RPC systems, and other systems infrastructure projects. I graduated with a Ph.D. in Computer Science from MIT. Before joining Google, I was a member of the research staff at DEC Systems Research Center in Palo Alto, CA.
