  • #49 - Nadja Kunz: Towards water stewardship in mining, understanding critical minerals, safer and sustainable resource management
    Sep 8 2025

    Nadja Kunz, Associate Professor at the School of Public Policy and Global Affairs, University of British Columbia (UBC), Canada shares her insights on the role of water in mining and the importance of critical minerals for the sustainable energy transition. Most notably, we gain insights into the complexity of the mining industry and its diverse and often forgotten stakeholders. What is required for us to make mining more sustainable, equitable, safe and future-proof?

  • The NotebookLM Mini Series #8: "Broken Telephone" - lost in translation between leapfrogging and Dunkelflaute (feat. Mashael Yazdanie)
    Aug 20 2025

    Welcome to this Mini-Series on The Grand Challengers Podcast! The topic of generative artificial intelligence (AI) has been in all our minds over the past few years and is gaining even more momentum with rapid advancements in text, audio and video. Google recently released NotebookLM, a powerful research-support AI that can generate not only summaries of sources that we feed it, but also entire podcast episodes. This Mini-Series will explore the power of NotebookLM, our live reactions to its outputs... and a deep dive into some of the topics that we have covered on the show. We feature previous guests, who are here to join in on the fun!

    Episode #8 tests whether NotebookLM can play "Broken Telephone". We generate an audio overview of a paper and use it as the basis to generate a new audio overview - rinse and repeat 20 times! What about across languages? Mashael Yazdanie (ep42) and I react to the final result. Will NotebookLM go off the rails or will it manage to keep the core message of the key research paper we used as a basis? Listen in to find out so that you do not have to test it yourself!

  • #45 - Lena Mutzner: “A list that keeps getting longer” - understanding pollutants of emerging concern for healthier aquatic environments
    Jun 16 2025

    Lena Mutzner, Group Leader in the Urban Water Management Department at the Swiss Federal Institute of Aquatic Science & Technology discusses the intricacies of stormwater quality monitoring. We learn a bit about how water quality is sampled, different pollutant types that she has focussed on and the ongoing challenge around contaminants of emerging concern. We also discuss the apparent paradox of repeating research cycles despite having done similar work 40 years ago, the importance of a holistic approach to stormwater management and how she is developing her research career into the uncertain future.
