Research Interests

I am interested in understanding how the physical ambients affect the cyber systems (e.g., sensor networks, wearables, data centers, etc) and exploiting certain properties of the physical ambients to improve the performance and resilience of the cyber systems. My ongoing research topics include:

  • Resilient CPS/IoT system functions (e.g., timing, synchronization, location, etc)
  • Low-power wide area networks
  • Thermal and energy control in data centers
  • Deep learning for sensing
  • Power grid control system security
