Research Interests

Hello, I am mainly interested in the area of computer architecture and systems. More specifically, I am interested in understanding how computer architecture can simplify the process of building correct yet efficient heterogeneous systems for important applications.

My research attempts to answer the following questions:

  • What is the interface that heterogeneous hardware systems should expose to applications?
  • How can these interfaces be supported efficiently in hardware?
  • Current works study systems consisting of CPUs and NICs connected via non-coherent interconnects (mainly PCIe).
