Adrian is the head of CEA. Initially from an organic chemistry, molecular biology and natural product discovery background in the agrochemical industry, Adrian has more than ten years experience in environmental chemistry and environmental fate of pesticides. In CEA, Adrian has a key role in working with clients to develop strategies for higher-tier exposure and risk assessments for Plant Protection Products undergoing development or re-registration. Areas of particular expertise include environmental risk assessment, modelling and product regulatory advocacy.

Peter is an industrial chemist with over 30 years industrial experience from laboratory work to senior management across a range of industries including aerospace, electronics, pharmaceuticals, industrial adhesives and industrial chemicals. His experience in legislative issues includes membership of the REACH committee of the British Adhesive and Sealants Association and their representative on the technical board of the European Adhesive Manufacturers Association (FEICA) between 2002 and 2004. During this period it dealt with the early issues associated with the REACH legislation. Peter has Chartered Scientist and Chartered Chemist status awarded by the Royal Society of Chemistry and is a member of the Chemical Hazards Communication Society.

Paul Mason is an expert in the environmental exposure assessments of chemicals. His PhD research, undertaken in collaboration with ADAS and HRI, focused upon point sources of surface water contamination from pesticides in agricultural catchments, with particular emphasis on the development of management techniques and engineering solutions to reduce contaminant losses. Paul's primary focus within CEA is to develop exposure scenarios and modelling solutions in the evaluation of the fate of pesticides, biocides and veterinary medicines within the environment. He is currently an independent expert on the OECD emission scenarios working group for indoor and outdoor uses of insecticides as biocidal products.

Simon is an environmental exposure and fate modeller and experienced software programmer. Simon specialises in the design and development of software tools for model parameterisation, automation and synergy, and for data extraction and management, constructing innovative software solutions for regulatory decision support systems.

Melanie is an aquatic ecotoxicologist specialising in the assessment of chemical risks to aquatic organisms, particularly in mesocosm studies. Melanie has worked in the chemical sector for the past six years and has a depth of expertise in conducting regulatory studies for commercial clients. She coordinates higher-tier aquatic projects within CEA and is responsible for planning and conducting laboratory and semi-field scale GLP compliant regulatory studies at internal or external facilities. In addition, Melanie has expertise in the evaluation and interpretation of aquatic ecotoxicology data and data gap analysis including recommendations on risk assessment strategies.

Alan is a terrestrial ecotoxicologist with a background in both public sector and contract research. He conducts risk assessments for terrestrial organisms and also acts as Study Director for terrestrial field studies. He has a particular interest in spatial ecology. Recent projects include development of alternative approaches to estimate exposure to arthropods, assessment of residues in arthropod food items of insectivorous birds and mammals and provision of position papers to support avian risk assessments.

Tim is an expert in the evaluation of the fate and exposure of pesticides in soils and water at the field scale. With more than twelve years experience, he has managed strategically important product defence studies for commercial clients and also programmes funded by UK Government focused on stewardship strategies to reduce the impact of PPPs, particularly in surface waters. He has recently managed the production of an expert report on PPPs for the European Crop Protection Association and is currently a coordinator for an industry sponsored project developing an environmental information source for a major herbicide.

Paul specialises in the environment fate and behaviour of pesticides. This includes the design and implementation of higher tier studies, performed at the semi-field and field scale throughout the UK and main land Europe. These are primarily GLP regulatory studies for industry clients in support of product registration. Paul's expertise is also applied to methods for reducing pesticide pollution of water bodies, in particular, investigating the fate and behaviour of pesticides in "Biobeds". He is currently evaluating the impact of different mitigation measures on diffuse pollution at the catchment scale.
