Dr Narelle Dybing is a parasitologist whose research investigates the hidden world of parasites and the role they play in wildlife health, invasive species ecology and biosecurity. After completing her PhD at Murdoch University, her work has focused on parasites carried by invasive animals such as feral cats, foxes, rats and wild dogs, helping to uncover how these often-overlooked organisms move through ecosystems and the risks they can pose to wildlife, livestock and even people. In th...

In this episode, I chat with spider researchers Dr. André Wanderley do Prado and Dr. Pedro de Souza Castanheira to explore the remarkable and often misunderstood world of spiders. André and Pedro share their journey from researching Brazil’s dense, biodiverse forests to working hands-on with Western Australia’s unique species at the WA Museum, where live specimens, fieldwork, and careful taxonomy all play a role in uncovering new insights into arachnid life. We dive into what it is like to w...
In this episode Kurt dives into the wild coastline of Western Australia with whale researchers Katy Fannei and Max Fabry, two scientists who built a groundbreaking whale-monitoring program from scratch, fueled by passion, volunteers, and community pilots. From flying light aircraft over 450 km of coastline to navigating remote beaches with drones and 4WDs, Katharina and Max reveal how a chance meeting led to a unique collaboration linking whale behavior with estuaries, drones, and citizen sci...
In this episode, I am joined by Professor Treena Burgess, Executive Director of the Harry Butler Institute at Murdoch University, and one of the world’s foremost experts on Phytophthora, to unravel the fascinating biology and devastating impact of this plant pathogen. Together, they explore what makes it so persistent, how it spreads, and why climate change and human activity have amplified its reach. From the challenges of containment and restoration to new research uncovering potential resi...
In this episode, I sit down with Professor Jennifer Verduin, Oceanographer and Pro Vice Chancellor at Murdoch University, with a passion for seagrass. Fresh from an expedition to Antarctica as part of a global leadership program for women in STEMM, Jennifer shares what it was like to stand among thousands of penguins, witness icebergs the size of cities, and confront the stark realities of a changing climate. Together, we explore the emotional and scientific impact of seeing global warming up...
In a world shaped by headlines, algorithms, and endless scrolls, who really controls the narrative? Associate Professor Tauel Harper, media scholar at Murdoch University, joins Kurt Krispyn to unpack the complex intersections of democracy, persuasion, and misinformation. From political spin and media ownership to social media’s sway over truth and trust, they explore how our beliefs are shaped, and how we can sharpen our critical thinking in an age of constant noise. A thought-provoking conve...
Conversation Between Trees wasn’t just another podcast recording; it was a moment that redefined the idea of the public lecture, a tradition that has been with us for centuries. Hosted by the Harry Butler Institute at Murdoch University, this was the first live podcast I’ve ever done, and it was an experience that meant so much to both Rachel and me. Together, in front of a vibrant, engaged audience, we celebrated Rachel’s promotion to Professor while weaving science, storytelling, and laught...
In a completely different field of science that I am used to, I sit down with clinical sexologist Melissa Hadley Barrett to talk about the science of sexual health and wellbeing. Melissa shares her expertise on common misconceptions around libido, erectile dysfunction, prostate cancer recovery, the role of hormones, and how lifestyle factors influence intimacy. The discussion highlights the importance of open conversation, evidence-based care, and a broader understanding of sexual health as a...
Cyclones are among the planet’s most powerful forces- reshaping coastlines, reefs, and ecosystems with every storm. Dr. Marji Puotinen, a spatial ecological data scientist from the Australian Institute of Marine Science, joins Paramount Importance to break down what cyclones really are, how they form, why they differ from hurricanes and typhoons, and what they mean for coral reefs, migratory animals, and our changing climate. From the physics of waves and storm tracks to the surprising ways c...
In this episode, I sit down with Mark Synnott legendary professional climber, author, National Geographic Explorer, and member of The North Face Global Athlete Team. One of the most prolific big-wall first ascensionists of his generation, Mark has pioneered routes on some of the most remote and untouched cliffs on Earth. He has climbed Yosemite’s El Capitan alongside Alex Honnold, summited Everest, searched the mountain’s north face for Sandy Irvine’s lost camera, and even spent seven years l...
Dive into the deep past of our oceans with evolutionary biologist Dr. Axelandre Siqueira, whose work uncovers the origins and transformations of coral reef fishes over millions of years. From rare fossil records to cutting-edge genetic research, Alexandra explains how mass extinctions, shifting climates, and reef expansion shaped the dazzling diversity of species we see today. In this wide-ranging conversation, we explore how fish evolved new feeding strategies, why coral reefs act as “fish ...
What happens when massive oil and gas platforms reach the end of their life? Are they just scrapped or could they become thriving artificial reefs?
