The Science Committee is a panel of science experts who lead the way in the development and implementation of organics research, including but not limited to:

  • Organic consumer product and service regulations
  • Organic manufacturing standards
  • Substance tests and viable safest alternatives
  • Toxin exposure risk
  • Food chain contamination
  • Circular economy packaging.

Impartial, transparent and scientifically accurate

The Science Committee monitors the latest changes in regulations and scientific knowledge, providing impartial, thorough, accurate and up-to-date guidance to the Organics Council ® policies and actions.

Assessing safety and sustainability

The Science Committee manages and conducts the substance tests and oversees the Organics Council ® Approved Substance List, working to an international gold-standard assessment protocol and providing the most comprehensive and thorough substance safety assessment worldwide. The Organics Council ® Approved Substances List, including the test outcomes, is an open-access resource.

Science Committee Director: Dr Esme Purdie

Science Committee Director: Dr Esme PurdieEducation and experience
Esme completed a BSc (Hons) in Medical Biochemistry at King’s College London University in 2004, before moving on to complete a PhD focusing on natural toxins in freshwater aquatic systems. Since completing her PhD in Analytical Chemistry and Environmental Toxicology at Dundee University in 2010, Esme has worked as a research associate on a number of academic research projects, and as an environmental consultant on numerous environmental health and protection projects. These include the recovery of soil after toxic contamination and the sustainable, post-disaster use of land.

Research
The TRAFFIC project: an Environmental Exposure and Health Initiative which entailed detailed chemical analysis of air pollution particles, investigating their sources, toxicity, characteristics and biological activity.
London Low Emission Zone Study: an investigation into the impact of London Low Emission Zone pollution from traffic on the health of school children in East London, involving analysis of the air quality around primary schools in the area. Health assessments of the children were then undertaken to measure respiratory health, biomarkers of exposure to traffic-related air pollution, genetic susceptibility to air pollution effects and systemic response to air pollution.

Science Committee Member: Dr Gonzalo Delgado

Science Committee Member: Dr Gonzalo DelgadoEducation and experience
Gonzalo gained a BSc in Chemistry from the Universitat Rovira i Virgili in Spain in 2007, specialising in organic chemistry and biochemistry before obtaining a master’s degree from Lund University, Sweden, in Molecular Biology in 2008. His master’s project looked into the subject of telomere homeostasis using yeast as a model organism. In 2014, Gonzalo gained a PhD in Biomedicine from the Institute for Research in Biomedicine of Barcelona, focusing on the functional interaction between two cell membrane proteins implicated in cell-extracellular matrix adhesion, amino acid transport and cancer development in human cells. Gonzalo has participated in several international and Spanish congresses and workshops, including the Spanish Society for Biochemistry and Molecular Biology and Federation of European Biochemical Societies Annual Congresses.

Research
Telomere homeostasis in yeast cells, studying DNA-binding characteristics of protein Cdc13. Further investigation of the interaction between 4F2hc and CD147 proteins, their role in amino acid transport, 1, 3-integrin function (cell adhesion and spreading) and their implication in cancer development and metastasis in mouse and human cells.

Science Committee Member: Dr Nicolas Goffette

Science Committee Member: Dr Nicolas GoffetteEducation and experience
Nicolas gained a BSc and an MSc in Molecular Biology from the Free University of Brussels in Belgium, in 2005 and 2007 respectively. His master’s project looked into the intracellular traffic of mRNPs involved in the post-transcriptional control of the TNF-alpha mRNA. In 2013, Nicolas gained a PhD in Molecular Biology from the Institute of Molecular and Medicine Biology in Gosselies, Belgium; the project was focused on the characterisation of regulatory mechanisms of TNF-alpha production by anti-inflammatory compounds within immune cells.
