Research

I am generally interested in mobile/edge AI systems, where I design and optimize networks and computer systems for supporting emerging (mobile) intelligent applications. Specific research topics include:

Here are some highlighted ongoing work:

DNNCare aims to enable automatic mobile/edge resource provisioning for deep learning based mobile applications (e.g., augmented reality, video analytics) through holistic resource management. The goals are resource efficiency, high throughput, low latency or SLA guarantee.
[SEC’20]

Griffin is a distributed storage service tailored for (collaborative) edge applications to share state/data. Griffin features designs that address challenges for the edge environment, which include expressive abstractions and consistency semantics and network-global monitoring and optimization for heterogeneity and mobility support.
[HotEdge’20]

INC proposes to use programmable switches to accelerate application-specific computations. We are exploring how to support modern workloads like machine learning with in-network computing and also provide abstractions to ease the use of in-network computing.

STEAM is a distributed back-pressure-based packet scheduler for service function chaining in packet processing networks, with the goal of high resource efficiency and low packet drop rates.
[INFOCOM’20]

SmartEdge is an edge resource management/orchestration framework with algorithms that make informed decisions on resource allocation and service placement in edge computing with proven performance guarantees.
