Biography

I am a Ph.D. student supervised by Prof. Kim, and my hometown is Fuzhou, China. I graduated with a BS degree conferred by Beijing Institute of Technology (BIT) and a BEng degree with the First-Class Honours awarded by The Australian National University (ANU) through their joint degree program. Now I am a research assistant at the WISEST Lab, and I also actively work with Prof. Kassem Fawaz at UW-Madison.

Featured Projects

Privacy-Enhancing Technique for Human-Centered Sensing

We are seeking to bridge the gap of user privacy in human-centered sensing. Eye tracking enables a more immersive experience for today’s user interface, while its rich information is exposed, inducing privacy concerns about users’ interest, health, identity, etc. Through the on-going project, we are exploring the opportunity to design real-time privacy control knob for eye-tracking in mixed-reality.

Rethinking Security and Usability of User Authentication

We developed a novel solution, Velody, for user authentication in smart homes using unique vibration responses from users’ hands. Thanks to the nonlinear properties in hand-surface vibration, Velody can generate a large number of secret keys resilient to various attack and accurately authenticate users in less than one second. This work has been published at ACM CCS 2019.

Hardware Support for Low-Power IoT

To better empower the applications, I am also interested in optimizing the underlying hardware for low-power devices. During our collaboration, we propose architecture designs that use approximate computing to reduce power consumption for various operations and their applications including image processing and neural network.

Automated Personality Computing

During my bachelor study at ANU and Data61, CSIRO, I was the first student to explore the opportunity of detecting users’ personality traits from the physiological indicators by machine learning. We conducted various user studies to collect user data during activities such as video-viewing and driving. The results indicate that unseen users’ personality traits can be accurately detected without the need of a long questionnaire. The work has been accepted by ACM CHI and ACM TIIS.
