Valentin Dalibard

I have completed my PhD dissertation in the Systems Research Group at the University of Cambridge, under the supervision of Dr Eiko Yoneki. I am interested in applying modern statistical models to computations, such as the ones performed by distributed systems, and using these models to make better static and runtime decisions. In the past, I have worked on systems to process large graphs on a single machine.
