ABOUT THE INTERVIEWEE Leon Barron received both a B.Sc. in analytical science (2001) and a PhD in analytical chemistry (2005) from Dublin City University (DCU), Ireland. Following four years of postdoctoral research into CECs in the environment, he moved to King’s College London as a lecturer in forensic science in 2009, where he led the Environmental and Forensic Chemistry group for 11 years. He was promoted to senior lecturer in 2015. He moved to Imperial College London in 2020 and was promoted to reader in analytical & environmental sciences that year. He has published more than 85 peer-reviewed articles in the fields of analytical chemistry, environmental pollution, ecotoxicology, and forensic science. He is a fellow of the Royal Society of Chemistry, the Chartered Society of Forensic Sciences, and the Higher Education Academy. He is also an elected member of the Analytical Science Community Council and the Separation Science interest group committee at the Royal Society of Chemistry.
