Mike Coulson
Senior Managing Scientist
Chemical Regulation & Food Safety
Harrogate (UK)

Mr. Coulson has an international reputation as a pesticide ecotoxicology expert and has over 30 years of experience working within the field. He has a proven track record in developing regulatory solutions to environmental issues. This includes both theoretical argumentation/justification and also experimental strategies for addressing major regulatory issues. Examples include higher tier testing strategies, finessed risk assessments and assessing the risk/ benefit of different techno- regulatory approaches.

Mr. Coulson is able to implement these strategies on behalf of clients, monitor any studies required, and provide revised/refined risk assessments to demonstrate regulatory acceptability. Mr. Coulson has written many expert papers on various aspects of environmental risk assessment and has had frequent dealings with European regulatory Authorities. Mr Coulson is a member of various Expert Groups and presents regularly at various International fora.

Within the bee and pollinator area, he has been involved with many different working groups including chairing the ICPPR (International Commission for Plant Pollinator Relationships) Working group on Semi- field and field testing for several years. He was a key contributor at the 2011 SETAC Pellston Workshop on Pesticide Risk Assessment for Pollinators. He has been involved in pollinator testing and risk assessment strategy in Europe, Canada, USA, Brazil and India.

Mr. Coulson was on the organizing committee and an editor for the third ESCORT (European Standard Characteristics Of Beneficials Regulatory Testing) workshop – proceedings issued in 2012. He is also on the Steering Committee of the upcoming SETAC workshop on soil organisms and non- target arthropods.
