Research areas
Areas of research include the application of advanced optical imaging, spectroscopic and remote sensing instruments for non-invasive and non-destructive investigation of materials, and applications of physical sciences to history, art conservation and archaeology.
Areas of research include:
1. Application of advanced optical imaging, spectroscopic and remote sensing instruments for non-invasive and non-destructive material identification
2. Multimodal analysis using a range of complementary imaging and spectroscopic techniques for the in situ and holistic investigation of cultural heritage objects with complex material composition
- Application of close-range mobile spectral imaging and spectroscopic systems for in situ spectral imaging of paintings, maps and manuscripts, to enable conservation monitoring, archaeological, architectural and art historical studies.
- Application of ground-based and airborne remote imaging and sensing systems [i.e. remote spectral imaging (in a variety of wavelength ranges), remote laser-based spectroscopy such as Raman, Laser-Induced Breakdown Spectroscopy (LIBS), Laser-Induced Fluorescence (LIF) spectroscopy] at stand-off working distances of tens of metres, developed specifically for the examination of wall paintings, archaeological sites and architectural monuments.
3. 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
4. Interdisciplinary research in the application of physical sciences to archaeology, history and collection care with a particular focus on the history of global connections
