Research Interests

My research interests are centred on understanding of fundamental flow physics and chemistry in microsystems, with the aim of utilising the research advances to develop new technologies with capabilities beyond any currently conceived. We have been developing lattice Boltzmann method to model microfluidic processing, so that the operational success of bio/chemical experiments may be predicted in a simulated virtual environment before the microfluidic devices are fabricated and tested. Recently, we also started to design microfluidic computing functions, exploiting the discrete nature of droplet motion in microchannel networks, in order to develop highly automated and integrated microfluidic systems.

Research key words: microfluidics, microdroplet technology, computational fluid dynamics, interfacial thermodynamics and hydrodynamics, non-equilibrium flows, lattice Boltzmann method
