OGTR regulates work with genetically modified organisms (GMOs) including for environmental releases. In his current role, he provides support to the office especially in relation to risk analysis, and he is interested in the implications of new technologies and other biological assessment frameworks for GMO risk analysis. His early work at OGTR included evaluating applications for environmental release of GM plants and he also has experience with legal and regulatory policy issues for GMOs. He has been active in OGTR’s international engagement, in particular in the OECD Working Party on the Harmonisation of Regulatory Oversight in Biotechnology (WPHROB) and took on the role of Chair of WPHROB in 2021.
