Understanding life through
the signals we cannot see.
I develop microwave and millimeter-wave sensing systems that reveal fine-grained physiological activity. My work connects radar hardware, signal processing and machine learning for human and animal health monitoring.
I work with Prof. Yongxin Guo at the State Key Laboratory of Terahertz and Millimeter Waves, City University of Hong Kong.
