Short Bio: I am currently a Postdoctoral Research Associate, working with Prof. Kyle Jameison, at Princeton University. Prior to my Postdoc, I received my PHD degree, in 2017, from Nanyang Technological University (NTU), under supervision of Prof. Mo Li.

Research Interest: My research focuses on wireless networked systems, including Internet of Things (IoT), Cyber Physical Systems (CPS) and 5G networked systems.

My research involves applying machine learning in the application layer, congestion control design in the transport layer, rate adaptation algorithm design in the MAC layer, and coding and hardware design in the physical layer.

Research Highlight: I implement and open-source the Atheros-CSI-Tool, which has been cited for more than 410 times (GoogleScholar) and has been used in more than 70 wireless sensing systems (check the list). I am a big fan of open-source! Check LTScope, the LTE physical layer monitor I recently released, which has been used in our SIGCOMM 2020 paper.

Currently, I am working on combining deep learning techniques with cellular and campus Wi-Fi signals to perform accurate, timely and privacy-preserving contact tracing for COVID-19, which is funded by both NSF and Princeton University.

I am on the job market this year, looking for a job in academia. Here is my CV.
