Research scope:
My research focuses on the integration of value added services such as Wireless Sensing, Mobile Computing and Computer Vision on Millimeter-Wave networking systems. The next-generation networking systems will be based on the high bandwidth and low latency millimeter-wave bands. Besides offering unprecedented multi-Gbps throughput and sub-ms latency [1, 2], millimeter-wave bands have abilities of fine-grained tracking of human movements [3], imaging hidden objects [4, 5] and sensing minute vibrations in daily objects or on human body [6].

1. Coexistence of human activity sensing on millimeter-wave networking system:
We are seeking ways to overcome the challenges associated with combining networking and sensing on the same hardware. This allows us to integrate wireless sensing of human activity on existing wireless indoor Access Points (AP), eliminating the need for additional infrastructure.

2. Imaging hidden objects with hand-held millimeter-wave devices:
Since millimeter-wave signals can penetrate opaque obstructions such as clothing, we propose equipping hand-held millimeterwave devices with imaging capability. This allows easy and fast screening systems for both security and maintenance.

3. Thermal characterization and heat dissipation of millimeter-wave devices:
Since millimeter-wave signal offer much higher bandwidth than conventional, low frequency radio signals, the radio frontends consume much higher power. This causes the devices to heat up much faster. To tackle the problem of device overheating, we first study the temperature characterization of millimeter-wave signals, and then, explored how we can exploit a multi-antenna design to mitigate this problem.
