Bare metal.
Cloud, end to end.

I’m a software engineer on Google’s GCE Bare Metal team. I think about bare metal end to end: how compute, networking, storage, and the control plane fit together into a cloud platform.

My perspective is grounded in the architecture of the whole system—the connections between physical infrastructure, machine lifecycle, and cloud services that make dedicated hardware reliable and usable at scale.

Compute & I/O

The physical foundations: processors, networking, and storage.

02

Control plane

Provisioning, orchestration, and the machine lifecycle.

03

System behavior

Reliability, operability, and performance across layers.

IN PRACTICE / SELECTED WORK

Google Cloud ×
CME Group

Ultra-low-latency trading

One application of this platform-level work is the low-latency trading platform I work on as part of the Google Cloud and CME Group collaboration.

The collaboration brings dedicated bare metal compute and deterministic networking to financial markets—combining the precision of physical infrastructure with the flexibility of the cloud.

02 / A LITTLE ABOUT ME

Systems thinker.
Curious by design.

I build at the intersection of cloud infrastructure, networking, and real-world systems.

Today, that means GCE Bare Metal at Google. Before that, I received my Ph.D. from the University of California, Los Angeles, advised by Prof. Songwu Lu, and my B.S. in Electronic Engineering from Shanghai Jiao Tong University.

My research spans networked systems, network security, edge and cloud computing, and mobile networks. A common thread: understanding how systems behave, then making them work better.

Less delay. More immersion.

Reducing LTE uplink delay for interactive mobile VR.

Less delay. More immersion.: how it works Mobile VR sends motion to an edge renderer and receives rendered frames. Application-layer inference, DRX doze reduction, and proactive scheduling prepare the uplink ahead of data arrival. Timing is illustrative, not a benchmark.
