My research vision is to create cost-effective sensing systems for mobile and IoT devices, enabling innovative applications across diverse fields. My interests span wireless sensing, networking, mobile computing, smart health, and human-computer interaction.
I obtained my Ph.D. degree in Software Engineering from Dalian University of Technology in 2022, under the supervision of Professor Lei Wang. I was a visiting scholar at UMass Amherst from 2019 to 2022, working with Professor Jie Xiong on wireless sensing and mobile computing.
I am now actively seeking postdoctoral positions to further contribute to research and teaching in Computer Science, Software Engineering, Information Systems and related areas.
