Gary is a skilled environmental fate specialist and risk assessor, having formed part of the scientific team at Brixham Environmental Laboratory (BEL) between 1985 and 2014 (ICI, Zeneca and then AstraZeneca). His broad experience encompasses a range of chemical industry sectors, including biocides, pesticides, industrial chemicals and pharmaceuticals.
Gary has experience of the use of QSAR models as a screening tool for selection of “greener” molecules. Since the introduction of environmental risk assessment for pharmaceutical ingredients in 2006, Gary has focused on the risk assessment of pharmaceuticals, developing novel approaches for tests, whilst satisfying international regulatory guidelines.
Gary has served on European scientific committees including the EU Biocidal Products Directive Notes for Technical Guidance, working with several large biocide companies to support them with compliance with the directive. Gary also chaired an ECETOC (European Centre for Ecotoxicology and Toxicology of Chemicals) Task Force, which developed interim guidance for the inclusion of Non-extractable Residues (NER) in environmental risk assessment.
He is currently a member of the ECETOC monitoring team overseeing the CEFIC (The European Chemical Industry Council) LRi (Long-range Research initiative) research project ECO 24, which aims to improve the prediction of NER formation using structural alerts and QSARs. Gary is also a member of the ECETOC monitoring team for ECO 25, which oversees a research project focused on the development of ecotoxicity tests for assessing the environmental risk of NER in soil.
