Research (Publication)

I care about systems software – mostly for computers consuming 10 Milliwatt – 500 Watt of power. Today they include sensors, smartphones/devices, and edge servers.

My kenshō on systems research (2018-12) PDF

At Purdue, I work with a group of students who share interest in systems software. See XSEL.

Our current work bases on two premises:

1. Old kernels (e.g. Linux) are firmware

Transkernel: unmodified Linux drivers on microcontroller-like cores (ATC’19 and HotMobile’17).
Overwatch: safeguarding unmodified file systems for IoT devices (preprint)
Power sandbox: power awareness redefined (Eurosys’18).

2. New OSes are defined by scenarios

StreamBox: stream analytics with manycores (ATC’17), with 3D-stacked memory (ASPLOS’19), and with Arm TrustZone (ATC’19).
VStore: managing large archival videos for analytics (Eurosys’19).

I worked on smartphone OS for my PhD, e.g. the K2 project which won an award in ASPLOS’14. Today, I continue to work on various mobile/wearable topics. See our group page for all projects.
