I am a tenure track Faculty at Max Planck Institute for Software Systems since March 2019.
Previously, I was a Software Engineer at Google Networking Infrastructure Team from Jan. 2015 to Feb. 2019.
From Nov. 2014 to Jan. 2015, I was a Research Scientist at Intel Labs.
From Mar. 2012 to Mar. 2014, I was a Post-Doctoral Researcher at Microsoft Research Cambridge, UK.
I received a Ph.D. in Computer Science at KAIST in 2012 under Sue Moon and KyoungSoo Park.
My research interest in end-host networking support including NIC, Kernel, RDMA, and RPCs.
Since 2012, I looked at network performance isolation and congestion control problems with the goal of providing latency guarantees in the datacenter networks.
