سامح النقيطي

Welcome! 

I am a researcher in distributed systems. My research interests focus on experimental software systems, including distributed computing, databases and operating systems.

I work in the cloud systems group  (led by Vivek Narasayya) which is part of the Extreme Computing Group (XCG) led by Surajit Chaudhuri in Microsoft Research in Redmond, WA, USA. 

I received my PhD from EPFL in 2007, working with Willy Zwaenepoel. I have master's degree from Rice University and bachelor's from Alexandria University.
