Research focus

My research focuses on networked sensing in various cyber-physical systems carried by humans, embedded in infrastructures (e.g., buildings, data centers, and smart grids), and distributed in wild environments. With an experimental basis, my research tries to understand how the physical processes affect the cyber systems (e.g., sensor networks and the broader Internet of Things) and exploit certain properties of the physical processes to advance the functional and non-functional (e.g., resilience) aspects of the cyber systems. My ongoing research topics include:

  • Sensing for resilient system functions (e.g., timing, synchronization, location, etc)
  • Embedded AI for sensing
  • Efficient and secure LoRa/LoRaWAN via radio sensing
  • Thermal and energy management in data centers
  • Secure sensing and control in smart grids
