Research interests

My primary interest is nuclear characterisation in support of decommissioning of both civil reactor operations and also industrial / research sites for waste sentencing and disposal.

My previous work has included development of novel and rapid approaches for analysis of tritium, in particular the development of a new high-capacity sample oxidiser for problematic waste streams.

My commercial experience also includes method development, validation, analysis and quality control in accordance with ISO/IEC: 17025 quality standards.

I am also experienced in radiation safety and open radioactive source work in relation to IRR and EPR regulations and in particular the requirements associated with the handling of LLW and ILW for preparation and analysis.
