Areas of research include the development of advanced optical imaging, spectroscopic and remote sensing instruments for non-invasive and non-destructive investigation of materials, applications of physical sciences to history, art conservation and archaeology.
- Optical Coherence Tomography (OCT): development of ultra-high resolution OCT, long wavelength OCT, polarisation sensitive OCT and multi-wavelength OCT from 550nm to 2000nm. OCT is applied to the non-invasive 3D volume imaging of paintings, enamels and other cultural objects to obtain subsurface microstructures and measurements of optical parameters through modelling of absorption and scattering properties of turbid media. We also applied OCT to a variety of fundamental science (soft matter physics), industrial and biomedical problems.
- Spectral imaging: mobile spectral imaging systems are being developed in a variety of wavelength ranges for in situ spectral imaging of paintings, maps and manuscripts, to enable conservation monitoring, archaeological, architectural and art historical studies.
- Ground-based and airborne remote imaging and sensing: 3D remote spectral imaging at stand-off distances of tens of metres, remote laser based spectroscopy at stand-off distances of tens of metres such as Raman, Laser Induced Breakdown Spectroscopy (LIBS), Laser Induced Fluorescence (LIF) spectroscopy have been developed specifically for wall paintings, archaeological sites and architectural monuments.
- Data science: development of machine learning/AI methods for the rapid analysis of a range of spectral imaging data from reflectance spectral imaging to X-ray fluorescence spectral imaging, and multimodal spectral imaging datasets
- Light-matter interaction: examination of the relationship between the material properties and the optical properties (including the effects of ageing) of varnish and paint material as well as the effect of laser damage on materials. Microfade spectrometry has been developed for in situ micro-destructive spectral/colour monitoring of the relative light induced fading rates of materials used on works of art.
- Multimodal analysis using a range of complementary imaging and spectroscopic techniques for the holistic investigation of complex materials
- Interdisciplinary research in the application of physical sciences to archaeology, history and collection care with a particular focus on the history of global connections
In her previous research, Liang also worked on Astrophysics topics such as observational cosmology, clusters of galaxies, radio interferometric telescopes and radio sources.
Opportunities to carry out postgraduate research towards an MPhil/PhD or MSc by research exist in all the areas identified above. Further information on MPhil/PhD opportunities may be obtained from the NTU Doctoral School.
