About me

I am a PhD student in Computer Science at the University of Illinois at Urbana-Champaign (UIUC), advised by Prof. Brighten Godfrey. Before joining UIUC, I worked with Prof. Shan Lu and Prof. Henry Hoffmann from UChicago to build an auto-configuration framework for systems software. I hold a bachelor degree in Computer Science from Bandung Institute of Technology, Indonesia, in 2017.

My research interests span broadly in the area of networked systems. My prior and current research are related to low latency networking, internet measurement, web applications, and VR/AR. Currently, I am working on few exciting projects: leveraging 5G different channels (or services) to improve mobile applications (including VR/AR), accurate 5G record-and-replay emulation, and offloading VR components to the edge and cloud.

Note: I am on the job market for 2025, looking for a research lab or research engineering position.
