Wireless communications with applications to structural problems, image processing and wavelet theory.

Dr Le's main research interests are in wireless communications with applications to structural problems, image processing and wavelet theory. His main research aim is to conduct multi-disciplinary research across a wide range of different fields, in particular, bonding electronic engineering and civil engineering with the ambitious goal of employing advanced electronic engineering techniques to civil engineering applications; a philosophy which is evidenced in his publications. Dr Le found and developed theoretical work on a hyperbolic kernel family and hyperbolic wavelet which have since found wide applications in signal processing, mechanical systems, medicine, image processing, engineering construction management and wireless communication. He is currently focussing on all aspects of the hyperbolic kernel and wavelet which can be utilised in wireless communications and civil engineering applications. Dr Le has continuously published in reputable peer-reviewed journals, and apart from publishing technical journal papers, he has been publishing engineering education peer-reviewed journal papers. Dr. Le is a member of the Civionics Group.
