I am currently a Senior Research Associate working with Prof. Cecilia Mascolo and an Affliated Lecturer at the Department of Computer Science and Technology, University of Cambridge. Prior to that I was a postdoctoral researcher working with Prof. Zhenjiang Li at City University of Hong Kong (from Oct 2020 to Dec 2021). I received the B.E. degree in Software Engineering from Xi'an Jiaotong University, Shaanxi, China in 2016 and the Ph.D. degree in Computer Science advised by Prof. Zhenjiang Li from City University of Hong Kong, Hong Kong, China in 2020.
I am focusing on developing intelligent mobile and wearable/earable sensing technologies for Internet of Things (IoT) systems with signal processing and Artificial Intelligence (AI) techniques to enable applications of Human Computer Interaction (HCI) and smart health.
