George is a steering member of the International Life Science Institute (ILSI) Health and Environmental Sciences Institute (HESI) Genetic Toxicology Technical Committee (GTTC) and co-chair of the quantitative subgroup. The ILSI-HESI provides an international forum to advance the understanding of scientific issues related to human health, toxicology, risk assessment, and the environment (for website link, see 'External Responsibilities' below). In 2013 alone, George was invited to give oral presentations at the Society of Toxicology (SOT, San Antonio), Procter & Gamble BioFusion Series (Cincinnati, USA), Health Canada Science Series (Ottawa, Canada) International Conference on Toxicology (ICT, Seoul, South Korea), IWGT (Brazil), International Conference on Environmental Mutagens (ICEM, Brazil) and the Industrial Genotoxicity Group (AZ, Alderley Edge, UK). The IWGT was a particular highlight, and the resulting consensus statements have been published in a series of manuscripts that provide expert advice, these manuscripts have a history of influencing ICH, OECD and other regulatory policy revisions, and will thus be of international impact. George has been lead academic on numerous international collaborations. These include FDA-NCTR, Health Canada, RIVM-Netherlands, AstraZeneca, Drugs for Neglected Disease Initiative (DNDi), Food Standards Agency, GlaxoSmithKline, Gentronix, Hoffman-La-Roche, Litron, PBR-Lab.s inc and more. He also continues to co-lead the DNA damage group (in vitro Toxicology group) in the Institute of Life Science, as well as teaching on the Genetics and Medical Genetics BSc degree schemes, and having a role as Director of Employability and Entrepreneurship for the College of Medicine. George was awarded the prestigious UKEMS Young Scientist Award in 2012, in 2013 he became a Fellow of the Higher Education Academy, and in 2014 he became a British & European Registered Toxicologist and also won the very prestigious EEMS Young Scientist Award.
