  • The NotebookLM Mini Series #6: These are neither the pollutants nor researcher you are looking for (feat. Lena Mutzner)
    Jun 23 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 #6 attempts to create a biographical piece - Lena Mutzner (ep45) reacts to how NotebookLM produces a deep dive discussion about her, using all her available publications, her PhD Thesis and up-to-date CV as sources. Will NotebookLM be able to capture the essence of her work and career to date?

  • #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.

  • The NotebookLM Mini Series #5: Plot Twist! Figure 3 says more than a thousand words and a third of the hot dogs (feat. Yannick Back)
    Jun 2 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 #5 delves into the links between water, energy and heat - Yannick Back (ep35) reacts to how NotebookLM produces a deep dive discussion (in English) of eight of his publications, all written in German and with different foci. This is the first experiment on this mini-series, which uses multiple sources.

    The 8 Papers were published from 2019 to 2024. Full details can be found in the show notes. Their German titles are:

    • 2019: Einsatzmöglichkeiten von Geoinformationssystemen in der Siedlungswasserwirtschaft am Beispiel Einbindung dezentraler Entwässerungssysteme zur Entlastung des städtischen Abwassernetzes
    • 2019: Untersuchung und Optimierung der Einbindung dezentraler Entwässerungssysteme zur Entlastung des städtischen Abwassernetzes und Minderung urbaner Hitzeinseln
    • 2020: Dezentrale Regenwasserbehandlung zur Entlastung der Kanalisation und Minderung urbaner Hitzeinseln
    • 2020: Urbanen Hitzeinseln und überlasteten Entwässerungsnetzen entgegenwirken
    • 2021: Latente Wärme vs. Sensible Wärme
    • 2021: Rolle der Energie- und Wasserflüsse im Stadtsystem: Steigerung der Resilienz unserer Städte zur Anpassung an die Auswirkungen des Klimawandels
    • 2023: Chancen und Herausforderungen bei der Gestaltung klimaresistenter dichter städtischer Gebiete mit Blaugrüner Infrastruktur
    • 2024: Die Rolle der Bewässerung städtischer Grünflächen während gleichzeitiger Trocken- und Hitzeperioden
