PhD Student @ EPFL, Switzerland
I am a Computer Science PhD student at École Polytechnique Fédérale de Lausanne (EPFL). My research focuses on cloud data center system design, with a recent interest on hardware/software co-design for higher resource utilization, performance and efficiency.
My ultimate passion lies in designing computer systems that further liberate and promote human productivity. Before joining EPFL, I obtained my master's degree at ETH Zürich and bachelor's degree at Harbin Institute of Technology.
