In this episode of Better Thinking, Nesh Nikolic speaks with Dr. Zhi Yi Ong about the neurobiology of food intake, exploring how gut-brain interactions shape eating behavior and its connection to addiction. Zhi Yi Ong is a Senior Lecturer and ARC Future Fellow at the UNSW School of Psychology. She completed her PhD in Biomedical Science at the University of South Australia and later undertook postdoctoral training in the Department of Psychology at the University of Pennsylvania. Zhi Yi's research focuses on the neurobiological mechanisms of feeding behaviors. Using multiple neuroscience approaches in animal models, she investigates how gut signals interact with brain circuits to regulate these behaviors. Additionally, she also examines how environmental factors and current treatments influence the neural systems that control appetite.

In this episode of Better Thinking, Nesh Nikolic speaks with Lana Tikhomirov about the intersection of AI and human decision-making, exploring its ethical concerns, cognitive challenges, and growing role in high-stakes fields like healthcare. Lana Tikhomirov is an AI safety researcher at the Australian Institute for Machine Learning, where she focuses on developing ethical, human-centered artificial intelligence systems for medical decision-making. Her interdisciplinary PhD bridges cognitive science, bioethics, and AI safety, examining a core question: How do humans make decisions using AI algorithms—and where should we draw the ethical line when replacing human judgment with machine logic? Lana’s work addresses the nuanced challenges that emerge when advanced deep learning systems—often opaque and difficult to interpret—are integrated into high-risk, real-world environments. As these technologies become increasingly common in critical domains, understanding their influence on human cognition and decision-making has never been more urgent. She is committed to advancing responsible and safe AI, and her research contributes to national policy and ethical guidelines for AI development and implementation in Australia.

In this episode of Better Thinking, Nesh Nikolic speaks with Dr Simon Byrne about evolving approaches to anxiety treatment—including CBT and ACT—and how evidence-based models can better support children’s mental health. Dr Simon Byrne is a Lecturer at the University of Queensland (UQ) since 2021. He completed a PhD/Masters of Clinical Psychology in child anxiety at Macquarie University. He has held postdoctoral positions at Yale Child Study Centre, as well as Westmead Hospital Psychiatry Department and Royal Prince Alfred Hospital in Sydney. His research has focused on 1) the unconventional use of psychiatric drugs to treat mental disorders in children, and 2) treatments for anxiety. He has a particular interest in the use of exposure therapy (“facing your fears”) to treat anxiety. He also teaches into UQ’s clinical psychology program and has conducted research into the use of simulations to teach ethics.

In this episode of Better Thinking, Nesh Nikolic speaks with Dr Poppy Watson about compulsive reward-seeking behavior, commonly seen in drug or gambling addiction, but also in more subtle forms that influence our everyday actions and habits. The research interests of Dr Poppy Watson lie at the intersection of motivation, attention and choice behaviour. A fundamental question in human psychology is whether we are totally in control of the choices we make and the extent to which we rely on environmental cues to guide our decisions. She is interested in the conflict that arises between our ‘good intentions’ (for example to eat healthily or avoid alcohol) and our innate tendency to be attracted by things that signal reward such as the McDonald’s golden M or the beer logo. She uses methods such as eye tracking and neuroimaging to examine this interplay between biased cognitions and habits on the one hand and explicit motivation on the other. She tries to understand the mechanisms that contribute to unwanted patterns of behaviour in both healthy and clinical populations. She is also involved in intervention projects (to improve treatment outcomes for patients and measuring the efficacy of these interventions) and is interested more generally in health psychology and behaviour change.
