Research interests

Thermal treatment of radioactive wastes

Understanding the processing, phase assemblages, and aqueous durability of thermally treated radioactive wastes. Principally vitrified and hot isostatically pressed inorganic wastes.

Fenton oxidation

Utilising this lower temperature oxidation process (<100 °C) for treatment of organic radioactive wastes, using mixed metallic catalysts. Particular interest in processing 14C bearing wastes.

Magnesium based cements

General interest in further understanding the chemistry and applications of magnesium based cements, notably magnesium phosphate (struvite) cements.
