    From DNA to Discovery: How Statistics Brings the Ancient Past to Life - with Dr Adam "Ben" Rohrlach & Dr Simon "Jono" Tuke

    How are statistics and data science transforming advances in genetic sequencing into new insights about how people lived, formed families, and organised their societies thousands of years ago? Our guests are Dr Adam “Ben” Rohrlach, an Australian statistician at the Max Planck Institute for Evolutionary Anthropology in Germany, and Dr Simon “Jono” Tuke, Senior Lecturer in the School of Mathematical Sciences at the University of Adelaide. From their early collaboration during Ben’s PhD to their ongoing work today, they’ve combined mathematical rigour with archaeological and genetic research to help uncover patterns in ancient human life that would otherwise remain hidden. Together, they’ve applied cutting-edge statistical methods to support major discoveries – including their contribution to the 2017 Eureka Prize–winning research confirming the connection between Aboriginal Australians and their ancestral lands. In this conversation, we revisit that work and dive into their latest research, using ancient DNA to reconstruct family networks in a European society from over 1,300 years ago. It’s a fascinating look at how collaboration across disciplines – and the power of statistics – can bring us closer to understanding the lives of people from the distant past. Our host is Dr Haripriya Sridharan – a MACSYS Research Fellow at The University of Melbourne.

    From Granular to Nano: Big Science at Small Scales – with Prof Natalie Thamwattana

    In this episode of The Random Sample, we explore the science of scale – from the behaviour of granular materials to the remarkable world of nanotechnology. Professor Natalie Thamwattana, an applied mathematician from the University of Newcastle, shows how studying the very small can lead to big insights across science and engineering. Her pioneering work in nanotechnology is helping unlock how some of nature’s smallest building blocks can tackle some of our biggest challenges – in medicine, energy, and electronics. In a field often dominated by heavy numerical simulations, Natalie was among the first to take a different path, developing analytical, formula-based approaches to understand the mechanics of carbon nanostructures. Alongside her research, Natalie shares a deeply personal story of growing up in Thailand and forging a path into mathematics. It’s a journey shaped by resilience, curiosity, and the support of her family – one that led to an international career at the forefront of applied mathematics. Our host is Cait Pryse – from The University of Melbourne.

    Tracking the Spread of Vaccine Hesitancy - with Prof Stacey Smith?

    Mathematics is often used to model how diseases spread. But what about the spread of information – or misinformation – about those diseases and their vaccines? Professor Stacey Smith? from the University of Ottawa is a trans mathematician whose research focuses on modelling infectious diseases. Increasingly, her work has turned to the social and behavioural dynamics that shape anti‑vaccination sentiment. In this conversation, we explore how mathematical approaches can help make sense of attitudes ranging from vaccine hesitancy to outright resistance, and why understanding these dynamics is critical for effective public health responses. The episode is hosted by Eva Stadler, a postdoctoral research fellow in the Infection Analytics Program at the Kirby Institute at UNSW Sydney. Together, Eva and Stacey discuss how tools from the mathematical sciences can be applied well beyond traditional epidemiology, intersecting with psychology, sociology, and communication science. This episode is part of a special two‑part series released to coincide with Women in Mathematics Day (12 May), celebrating the contributions of women – and those who identify as women – in the mathematical sciences worldwide. The other episode in the series explores how the mathematical sciences are playing an increasingly important role in understanding women’s health.

    What Maths can tell us about Women's Health - with Prof Alys Clark & Dr Claire Miller

    Mathematics is not often associated with women’s health, yet the mathematical sciences are playing an increasingly important role in understanding pregnancy, reproductive health, and chronic conditions that disproportionately affect women. Professor Alys Clark and Dr Claire Miller, both from the Auckland Bioengineering Institute at the University of Auckland, use mathematics to shed light on complex health challenges faced by women, including pregnancy and endometriosis. In this episode, they highlight the importance of interdisciplinary collaboration, particularly between mathematicians, biologists, and clinicians. In a twist on our usual format, Alys and Claire interview each other, offering a candid and engaging look at their research, their collaborations, and what it’s like to work at the interface of mathematics and medicine. This episode is part of a special two‑part series released to coincide with Women in Mathematics Day (12 May), celebrating the contributions of women – and those who identify as women – in the mathematical sciences worldwide.  The other episode explores how mathematics can help us understand the growing challenge of anti‑vaccination sentiment.

    Game Theory: The Mathematics of Strategic Choices - with Dr Maria Kleshnina

    Each year, the L’Oréal-UNESCO For Women in Science Program recognises a small number of exceptional female early‑career researchers in Australia and New Zealand with a prestigious fellowship. In 2025, for the first time since the program began in 2007, the award went to a mathematician: Dr Maria Kleshnina from QUT’s School of Mathematical Sciences. Maria’s research is in game theory – an interdisciplinary field grounded in the mathematical sciences that studies how people make decisions when their outcomes depend on the actions of others. In this episode, we explore why game theory matters, the kinds of real‑world problems it is designed to tackle, and how it has become a powerful way of thinking across economics, politics, and – in Maria’s area of interest – conservation. Maria is a Senior Lecturer at QUT, an Australian Research Council DECRA Fellow, and a Chief Investigator with the Securing Antarctica’s Environmental Future initiative. We spoke with her about her research, her career journey, and what it means to be awarded a L’Oreal-UNESCO Women in Science Fellowship. Our host is Dr James Nichols.

    The Kalman Filter: The Mathematics of Knowing Where You Are

    The Kalman filter is a hidden mathematical tool with an enormous impact on our daily lives. Most people have never heard of it – yet it quietly powers everything from spaceflight and aviation to our GPS, smartphones, and wearable devices. Developed in the late 1950s and early 60s, the Kalman filter provides the optimal solution to this problem: If you have an imperfect prediction of where something should be…and a noisy measurement of where it seems to be…what’s the best estimate of where it actually is? And more remarkably – it lets you answer that question over and over again, in real time. In this episode, we explore the origins, ideas, and lasting influence of the Kalman filter with two world‑leading experts, Laureate Professor Emeritus Rob Evans and Professor Bill Moran from The University of Melbourne. Along the way, we unpack concepts like least squares, minimum mean square error, and even dip into probability and statistics, including Bayes’ Theorem. But don’t let that scare you off – because this is a story about powerful mathematics hiding in plain sight – and quietly shaping the technology we rely on every day. Our host for this episode is Dr Tom Kimpson, a Postdoctoral Research Fellow with MACSYS at The University of Melbourne.

    Maths Meets Biology: Inside the Mission to Model a Living Cell - Part 2

    Scientists are generating more biological data than ever before, and new technologies now allow us to peer inside the cell in ways we couldn’t have imagined a decade ago.  But even the most advanced tools can’t explain how a living cell actually works as a complete system. That’s the challenge at the heart of the Australian Research Council (ARC) Centre of Excellence for the Mathematical Analysis of Cellular Systems (MACSYS). The Centre brings mathematicians and computational scientists together with biologists to pursue a bold goal: building a predictive, fully computational model of a living cell. This is the second episode of our two-part series on MACSYS.  Our guests are the leaders of MACSYS - Centre Director Professor Trevor Lithgow and Deputy Director Professor Jennifer Flegg. Together, they explore what a whole‑cell model is, why it matters, and how bridging wet‑lab and dry‑lab science is essential to tackling one of the most ambitious challenges in modern biology. Our host for this episode is Dr Haripriya Sridharan – a Postdoctoral Research Fellow with MACSYS at The University of Melbourne.

    Maths Meets Biology: Inside the Mission to Model a Living Cell - Part 1

    Understanding a living cell is one of the biggest challenges in modern science. Cells carry out an extraordinary number of tasks every second and understanding how all those processes fit together is central to biology. But even with advanced experiments and mountains of data, scientists still don’t have a complete picture of what a cell does – or how it might respond to new conditions or interventions. The ARC Centre of Excellence for the Mathematical Analysis of Cellular Systems – or MACSYS – aims to change that. MACSYS brings together mathematicians and computational scientists to work alongside biologists toward a bold goal: creating a predictive, fully computational model of a cell. The Random Sample is excited to partner with MACSYS as our principal new partner organisation. To introduce you to the Centre’s work, we’re bringing you a two-part series. This first episode takes a mathematical lens, featuring two of the Centre’s mathematical modellers and Chief investigators: UNSW Professor Adelle Coster and QUT Professor Mat Simpson. Together, we explore how modelling helps make sense of biological data, how collaboration across disciplines pushes science forward, and why whole‑cell modelling demands both mathematical insight and biological intuition. Our host is Tim Macuga. Episode webpage: https://www.therandomsample.com.au/podcast/macsys-pt1/ See omnystudio.com/listener for privacy information.
