  • The NotebookLM Mini Series #6: These are neither the pollutants nor researcher you are looking for (feat. Lena Mutzner)
    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?Podcast Intro/Outro Song: Funky Fortune by Danny Shields (Check out more of his tunes over on Spotify: https://open.spotify.com/artist/7vRFEGMyTTfeCtc8qiUB82?si=dygdqu9IQLSFYNvVzPNu5w)Chapters:0:00 Intro1:26 Guest Intro and AI Impressions3:12 Guest prior experience with AI8:49 AI for Graphic Design in Research & Communication9:59 How this experiment works12:16 The human summary - or setting expectations13:47 Live Reaction41:39 Post-discussion47:23 Evaluating the analogies49:29 Discussing the accuracy and inner workings52:53 Wrap Up54:46 Outro Detailed shownotes over at: petermbach.com/podcast for more in-depth information about each episode.Join the community over at: linkedin.com/company/tgcpodcast and let's connect across the world!Subscribe and listen to the podcast (and do please leave a review/rating) on Spotify, Apple Music, YouTube or wherever you get your podcasts from.

  • #45 - Lena Mutzner: “A list that keeps getting longer” - understanding pollutants of emerging concern for healthier aquatic environments
    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.Podcast Intro/Outro Song: Starsky by Alex Keren (Check out more of his tunes over on Spotify: https://open.spotify.com/artist/5vZ3lENfDLjkln8scBJ8mW)Chapters:0:00 Intro1:59 Guest Intro & Meditative Activities4:16 Nordic Countries vs. Switzerland7:36 Lena's Mission in Water Quality10:53 How it all started - engineering or psychiatry?13:18 Contaminants of emerging concern16:48 Studying Water Quality 10126:28 Which contaminants does Lena focus on?29:28 Tyre wear leachate and 6PPD-Quinone33:01 Data issues towards building water quality understanding36:45 Different types of common micropollutants40:55 Interplay of Modelling and Water Quality Data Collection46:18 Effect-based measurements48:19 The holistic view - integration as a the way forward51:05 Mitigation of pollution through Blue-Green Infrastructures54:00 Lena's Future Research Trajectory56:49 Q&A Start57:24 What does innovation mean to you?1:00:30 Key Moment, Person, Event1:03:52 Women in STEM - Lena's drive to be a role model1:06:40 Time Management1:10:24 Favourite childhood memory1:12:55 Biggest challenge to date1:18:17 Advice for young researchers1:20:00 What would you most like to be remembered for?1:21:15 Where can people find you?1:21:57 Final Message1:22:15 OutroDetailed shownotes over at: petermbach.com/podcast for more in-depth information about each episode.Join the community over at: linkedin.com/company/tgcpodcast and let's connect across the world!Subscribe and listen to the podcast (and do please leave a review/rating) on Spotify, Apple Music, YouTube or wherever you get your podcasts from.

  • The NotebookLM Mini Series #4: Jalapeños as part of the urban form and a lesson in Dutch (feat. Martijn Kuller)
    Welcome to this Mini-Series on The Grand Challengers Podcast!

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 #4 delves into "Water sensitive urban design as part of the urban form" -  Martijn Kuller (ep3) first reacts to how NotebookLM produces a heavily prompted deep dive discussion (my work of art) of an older review we co-authored, highlighting the ease with which prompting can get dangerous and misleading if not in the right hands. We then both react to an Audio Overview of the same review produced by Google Gemini 2.5 Pro, the LLM upon which NotebookLM is based - shorter and more concise.Full Reference to the Paper: Kuller, M., Bach, P.M., Ramirez-Lovering, D. and Deletic, A., 2017.
