About Me

I have graduated from the Systems Lab of Computer Science Department at Cornell, and will be joining Facebook, Menlo Park as a Research Scientist. With my advisors Ken Birman and Robbert van Renesse at Cornell, I worked on distributed systems, networking and storage in the context of cloud computing.

My thesis research focused on analyzing and designing advanced caching solutions for the modern Web applications. Thanks to the support of Facebook Graduate Fellowship and a close collaboration with a few infrastructure teams at Facebook, I have been able to work on real caching systems in production for serving static content as photos and dynamic content as social graphs interactions.

Previously, I have also worked on topics related to content delivery across wide-area network, such as Gossip, Multicast and P2P live streaming. In general, I am interested in understanding the principle idea and deep trade-off that can make real systems scale, perform well and tolerate failures.

  • Mentoring

    During the 2011-2012 school year, I have been involved in mentoring a MEng project (Landmark Recognition Cloud System) supervised by Ken Birman, Noah Snavely and Daniel A. Freedman. I was extremely lucky to get the opportunity to work with a group of great students: Ansu Abraham (2011), Hee Jung Ryu (2011), Kaushik Nataraj (2011-2012), Scott Phung (2011-2012), Abdelrahman Kamel (2011-2012), and Shivendra Singh (2011-2012)

    The project won the CS M.Eng 2012 Team Project of the Year award and BOOM 2012 Competition Innovation award.
