Jonathan Kaldor

Research Scientist - Core Systems

I am a Research Scientist at Facebook, working on our internal infrastructure. Currently I am working on our cluster management system, in particular the scheduling and allocation components. Previously, I have also worked on distributed tracing and observability, dynamic video compositing, and mobile performance and interactivity.

Prior to joining Facebook I received a PhD in Computer Science from Cornell University in 2011 and a Bachelor’s degree in CS/Math from Amherst College in 2003.
