Staff profile

I am a physicist by training. I obtained my PhD degree in 2000 from Shanghai Institute of Optics and Fine Mechanics (SIOFM), Chinese Academy of Science (CAS), China, with expertise in fibre-based confocal scanning microscopy, optical interferometry, and ultrafast laser spectroscopy.

In 2001-2003, I worked in Optoelectronics group under Prof. McCabe at Trinity College Dublin, as a research associate, focusing on the application of confocal scanning microscopy and the development towards real-time acquisition.

In 2003-2005, I worked in Femtosecond Laser laboratory under Prof. Fumagalli at Free University, Berlin, as a research fellow and built a two-colour pump-probe laser system. We studied the ultrafast spin dynamics of the magnetic material at ultra-low temperature (16.5K).

Since 2007, my research has been guided towards complex fluids and substrates in a Physical Chemistry group led by Prof. Bain at Durham University, developing techniques on the characterisation of dynamic properties of complex fluids and their interactions with substrates. For nearly 20 years, I have been working closely with academic researchers and industrial R&D scientists across the UK and beyond. We are focusing on the fundamental understanding and the control of droplet formation in flight, droplet spreading and drying, liquid wicking in porous media, and deposit adhesion on a substrate. The work has been beneficial to inkjet printing and textile cleaning in precision process controls and product optimisations.

My current research interests are in the field of flexible opto-electronic sensors and healthcare devices. With the collaboration in interdisciplinary teams, we are keen to link the model systems and the real world, and gain insights and controls for a greener and healthier environment.
