- Main Research Interests - Environmental Analytical and Forensic Chemistry
- Individual particle analysis using computer controlled scanning electron microscopy coupled with energy dispersive X-ray detection and Raman spectroscopy
- Characterisation of environmental particles of respirable size and their bioaccessibility with reference to toxic and carcinogenic components
1. Air pollution:
Air pollution is studied, with specific interest to its effects on buildings, artefacts and humans. Air quality is determined with reference to particulate matter concentration and chemical composition, as well as gaseous pollutant identification and concentration. These are related to the degree and type of degradation of materials used in artefacts and buildings upon exposure. In addition, these findings are used to determine potential toxicological and carcinogenic impact on humans.
2. Materials characterisation
A study of the chemical character of various types of materials, mostly industrial minerals, is performed with the specific interest of probing industrially- related questions and problems. Characterisation of C-containing materials is of specific interest, with special focus on coal and its by-products from the gasification and combustion industries. A multiple analytical technique approach is used with specific expertise in Raman Spectroscopy coupled with CC-SEM/EDS.
