I am a mathematician working at the HKUST Jockey Club Institute for Advanced Study [IAS] in Hong Kong. Apart from mathematical topics I am interested in the Free Software movement [FSF] and photography.
I have expertise in mathematical inverse problems and scattering theory. Most recently I have focused on three topics: the behaviour of waves near sharp corners, backscattering, and the propagation of waves in networks. The latter concerns assessing the quality of water supply pipes remotely using pressure waves.
Some keywords: corner scattering, non-scattering energies, transmission eigenvalues, backscattering, hyperbolic problems on graphs.
