I am a Senior Director of Engineering at Meta/Facebook. I currently work on AI and Systems Co-design, encompassing AI, LLM, GPU/accelerator, hardware and systems software in general. Previously, I worked on Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and database in Meta's planetary-scale private cloud, comprising millions of machines and offering capabilities similar to those of public clouds. Prior to Facebook, I was a research scientist and manager at IBM T.J. Watson Research Center. 

My research publications might help shed some light on my past work; see the full list at Google Scholar.
