I am currently working as a Principal Research Scientist at Nokia Bell Labs in Cambridge, UK and lead the Device Systems team.
In my team, we work on building multi-device systems to support collaborative and interactive services. With an unprecedented rise of on/near-body devices, it is common today to find ourselves surrounded by multiple sensory devices. We explore system challenges and issues to enable multi-device, multi-modal, and multi-sensory funtionalities on these devices, thereby offering exciting opportunities for accurate, robust and seamless edge intelligence.
My research interests include mobile and embedded systems, edge intelligence, tiny ML, Internet of Things (IoT), and social and culture computing. I enjoy building real, working systems and applications and like to collobrate with other domain experts for interdisciplinary research.
We are hiring multiple research scientists for the research topic of collaborative edge systems at Cambridge, UK! Come work with us.Click HERE for the detail.

Intelligent cameras such as video doorbells and CCTV are abundant today, yet only used for a single-purpose, privacy-invasive and bandwidth-heavy streaming. We have developed a software solution that transforms intelligent cameras with automated machine learning operations (MLOps), enabling them to provide a range of services, including traffic flow, pedestrian analysis, asset tracking, or even facial recognition.
Multiple intelligent devices on and around us are on the rise and open up an exciting opportunity to leverage redundancy of sensory signals and computing resources. We are building multi-device systems to make an inference of ML models accurate, robust, and efficient at the deployment time so that applications can benefit from such multiplicity and boost the runtime performance of deployed ML models without model retraining and engineering.
The embedded accelerators promise model inferences with 100x improved speed and energy efficiency. In reality, however, this acceleration comes at the expense of extreme tight coupling, preset configurations, and obscure memory management. We challenge these limitations and uncover immediate opportunities for software acceleration to transform the on-chip intelligence.
