Iain Robertson has always been interested in applying chemical techniques to solve environmental problems; it is a journey that has taken him from chemistry though archaeology, botany, geology and now geography. His PhD investigated the response of oak trees to environmental changes (Department of Plant Sciences, University of Cambridge). His main research focus has been upon achieving a better understanding of natural climatic variability using stable isotopes in tree-rings. In recent years, he has investigated the use of amended biochars to reduce environmental pollution from abandoned metal mines. He is a Chartered Chemist (CChem FRSC), Senior Fellow of the Higher Education Academy (SFHEA) and was the President of the Tree-ring Society (2018-2021). He is the co-author of 75 scientific papers. He was awarded the prestigious Agnese Haury Training Fellowship at the Laboratory of Tree-Ring Research at the University of Arizona and was a Visiting Professor at the Nicolaus Copernicus University.
