1. Uncovering chemical biodegradation in the environment - Kathrin Fenner, Eawag

   Mar 2, 2026

   In this episode I speak with Prof. Kathrin Fenner, one of the leading academic scientists in the study of chemical biodegradation and environmental persistence. Kathrin and I have a far-reaching conversation covering her background and research interests, challenges and developments in chemical biodegradation research, and implications for policy and society. We have learned an enormous amount about the fate and persistence of chemicals in recent years, and the work of Kathrin and her group has been at the heart of this. Listen to the episode to find out about biodegradation of chemicals in different environmental settings, what factors contribute to persistence, understanding transformation products and pathways, predicting biodegradation for different chemicals and scenarios, and how we can utilise this knowledge toward safer and more sustainable use of chemicals.

2. Chemicals in our language - Joanna Gavins, University of Sheffield

   Jan 29, 2026

   In this episode I speak with Joanna Gavins, who is a professor of English Language and Literature at the University of Sheffield. Joanna and I discuss the language we use and how this influences the way we think, feel and act in relation to choices we make, the environment, and chemicals. We start off by discussing the work Joanna has been doing at the Bio-based and Biodegradable Industries Association (BBIA) on how to effectively communicate information about sustainability to consumers. We also delve into our complex relationship with nature, and how this is influenced by language. Our conversation then moves onto chemicals. We do a deep dive into the language surrounding chemicals in modern discourse, and how this influences public perception and emerging policy. We talk about the issue of chemicals in the environment, how this relates to us, and how we might get better at talking - and thinking - about these issues. I hope you will find this discussion as fascinating as I did!
