The Random Sample

Here’s something weird to think about. Can fluids think? No, we’re not talking about a liquid metal shape-shifting creature like what we saw in Terminator 2. We’re asking, can fluid systems make computations? In this episode, we chat with Professor Eva Miranda, head of the Laboratory of Geometry and Dynamical Systems at the Polytechnic University of Catalonia in Spain. She’s on a mission exploring...

Sometimes interesting research starts with a question faced by industry. That question may lead to other questions – and maybe even shine light on a broader research problem not specific to that industry. Collaboration between academia and industry allows researchers to identify and explore these new and interesting problems. One way that’s being done is through Industry PhDs. In this podcast, we...

This is a special edition of The Random Sample! We’re on the road at the World Statistics Congress taking place from 15-20 July in Ottawa, Canada. The Congress is put on by International Statistical Institute (ISI) and is the largest congress worldwide for statisticians and data scientists. In this podcast, we hear from Stephen Penneck, ISI President; Kerrie Mengersen, ISI Vice President; Anil Aro...

Our guest is Mine Çetinkaya-Rundel, a Professor in the Department of Statistical Science at Duke University in the United States. Mine’s work is so much more than just educating students about statistics and data science. She’s a big proponent of what she calls ‘open education’, the open source sharing of how stats and data science are taught, and innovating the pedagogy. In this episode, we explo...

For three decades, University of Queensland Professor Hugh Possingham has combined his two passions – mathematics and nature – into a career dedicated to making an impact with conservation efforts around the world. Hugh recently completed a two-year term as Queensland’s Chief Scientist. He served as Chief Scientist of the Nature Conservancy, is the former director of four national research centres...

Ever watch a TV courtroom drama where they question an expert witness? Chances are, you’ve never seen an actor portray an expert witness who is a statistician. But statisticians can have a big impact inside real courtrooms. Our guest is Professor Ian Gordon, Director of the Statistical Consulting Centre at The University of Melbourne. Among the consulting work he does includes being an expert witn...

100 years after Albert Einstein predicted their existence, scientists in 2015 detected gravitational waves for the first time ever. The historic discovery was the culmination of decades of research and hard work. In this episode, we explore the importance of gravitational waves and the theoretical and technological efforts that allowed researchers to finally detect them. Our guest is Distinguished...

We explore the field of discrete optimisation and how industries and companies use it to make decisions for complex problems. Our guest is Monash University Professor Peter Stuckey, a pioneer in constraint programming (CP) which is a powerful approach to solving discrete optimisation problems. Professor Stuckey explains why he believes optimisation is the intelligence behind AI. Our host is Dr Sev...

It’s one of the most pressing, if not the most pressing, question facing scientists: what impact is climate change having on our planet’s future? In this episode, we chat with world-renowned climate researcher Professor Lisa Alexander from UNSW who is helping answer that question with her research to understand and build better climate models. Our host is Rose Crocker. See omnystudio.com/listener...

Since its release in late 2022, Open AI’s Chat G-P-T has most everyone talking about it, and even trying it. Schools, universities, and businesses are scrambling to figure out how it can be used, or whether to even ban its use. But here at The Random Sample, we’ll leave that debate to others, at least for now. Instead, we’d rather take a look under the hood of ChatGPT and see what it really is and...

There's a global movement underway to tackle gender equity issues in Data Science. In 2015, Women in Data Science, or WiDS, was created. What started out as a conference at Stanford University has now grown into a worldwide initiative, with events in more than 200 countries, including Australia. In this episode, we chat with the Co-founder and Executive Director of the WiDS movement, Emeritus Prof...

Every two years, Australia’s applied mathematics community invites a distinguished international academic to speak at universities across Australia. This year, the AMSI-ANZIAM Distinguished Lecturer is Professor Konstantin Avrachenkov, Director of Research at France’s National Institute for Research in Digital Science and Technology, or INRIA. The Random Sample caught up with Prof Avrachenkov at t...

With the explosion of data everywhere, how do you prepare for the exciting new careers and jobs of the future, when many of them don't exist yet? With maths, of course!  See omnystudio.com/listener for privacy information.

The Fields Medal is the top award in mathematics and for only the second time ever, a woman has won it. In this episode, we explore the problem that Ukrainian mathematician Maryna Viazovksa solved and why it's so important. See omnystudio.com/listener for privacy information.

The Statistical Society of Australia turns 60 years old this year. In this episode, we celebrate this big milestone as we explore what the Statistical Society offers its members, look back at some of its history, and peek into the future, especially with the recent emergence of data science. Our guests are current SSA President Professor Ian Gordon, and SSA Immediate Past President, Associate Prof...

One of the biggest challenges facing scientists in Australia is trying to protect and save a national treasure, the Great Barrier Reef. To do that, though, they need to understand it better. But this is not just a problem for ecologists and marine biologists to tackle. Mathematical and data scientists are heavily involved in the effort to save the reef. In this episode, we explore some of the ques...

At the end of 2021, our Centre, the Australian Research Council Centre of Excellence for Mathematical and Statistical Frontiers, finishes up. ACEMS brought together researchers across the mathematical sciences, from the theoretical to the very applied. In this episode, we explore the impact ACEMS has had on those sciences, and beyond, to organisations in government and industry. Plus, our most imp...

Mathematics is exciting, enjoyable, and can surprise you, right? To help students to experience that when they do maths in the classroom, ACEMS has helped foster and grow a program called 'MathsCraft'. The program is designed to introduce to students in years 5 to 10 to the ‘doing’ of mathematics like, well, a mathematician! In this episode, we talk to three teachers in South Australia who are now...

Thanks to the efforts of ACEMS Chief Investigator Rob Hyndman, the School of Business at Monash University now recognises software as a first class research output. In this episode, we will explore the role of software in the research process, including both the opportunities and challenges for researchers creating it, and whether other universities might follow the lead set by the Monash Business...

The European Meteorological Society just awarded an ACEMS researcher and her colleague in the Netherlands its top prize for innovation in meteorology. Their project sets out to develop new statistical methods to quality control wind data captured by amateur, or citizen, scientists and integrate that data with wind observations from official weather stations. That could give forecasters and others...
