As a professional scientist, Declan has an impressive record in environmental due diligence, risk management, environmental impact assessment and environmental research.

Over the last 25 years, Declan has overseen the environmental management of several industrial operations as well as delivering solutions for client’s complex environmental challenges in developing renewable energy and waste management projects, assessing and managing contaminated land restoration projects, water management, acoustics and environmental impact assessment.

Declan has also worked as a research scientist in several large-scale EU funded collaborative research projects in life cycle assessment and environmental management of industrial projects with European universities, as well as spearheading and delivering a national research project for the Environmental Protection Agency.

Since 2012, Declan has devoted considerable time and resources to independently assess the environmental and health risks associated with fluoride exposure, in addition to undertaking due diligence examination of community water fluoridation. Declan undertook the first risk assessment of fluoride intake from tea in the Republic of Ireland, addressing its implications for water fluoridation.

In addition, Declan recently published a similar study of fluoride intake from tea in New Zealand. This comprehensive study also reviews the international evidence regarding chronic fluoride intake and its association with chronic pain, arthritic disease, and musculoskeletal disorders and provide insights into possible association between fluoride intake and the high prevalence of these disorders in New Zealand.
