Research Interests

My research mainly focus on applying computer science and signal processing technologies in civil engineering area to make our city green and smart.
In particular, my current works cover non-destructive testing of water grid using acoustic waves, optimizing smart sensor network in infrastructures, energy harvesting from infrastructures and smart city.
I'm also interested in acoustic wave modeling, inverse scattering techniques and nonlinear inversion methods. My previous work also includes ocean environment inversion, underwater acoustics, underwater localization and robot navigation.
