Tracks
Track 5
Friday, November 13, 2026
3:15 PM - 4:45 PM

Speaker

Dr Shauni Omond
Postdoctoral Research Fellow
Brigham and Women's Hospital / Harvard Medical School

Shiftwork sleep/wake schedule rotation rate impacts sleep and neurobehavioural performance

3:15 PM - 3:21 PM

Biography

Dr. Shauni Omond specialises in sleep and circadian science, focussing on understanding how sleep, biological rhythms, lighting, and travel-related factors influence human health and performance, with aooplications in athletic and shiftwork populations. She completed her PhD in sleep ecophysiology and has extensive experience in human laboratory and field-based research. Dr. Omond is passionate about science and science communication, aiming to brdige rigorous research with practical, real-world outcomes in performance and health.
Prof Peter Catcheside
Professor, College Of Medicine And Public Health
Flinders University

Circadian-informed lighting delays final awakening during simulated night-shift work

3:21 PM - 3:27 PM

Biography

Prof Catcheside completed his PhD in exercise physiology and worked in exercise, respiratory and sleep scientific support roles before joining the Adelaide Institute for Sleep Health in 1997 and Flinders University in 2012 through an ARC Future Fellowship. His research seeks to advance evidence-based measurement practice improvements and understanding of physiological mechanisms underpinning breathing, sleep and circadian disruption in sleep medicine. Current research is developing new methods to quantify ventilation and breathing effort during sleep, and daily body-clock timing, to help improve and streamline healthcare for people with a broad range of sleep problems.

Dr Prerna Varma
Senior Lecturer
Monash University

Who benefits from a shiftwork app? Trialling SleepSync in healthcare

3:39 PM - 3:45 PM

Biography

Dr Prerna Varma is a Senior Lecturer in the School of Psychological Sciences, Monash University, where her research sits at the intersections of sleep, circadian biology, digital innovations and health equity. Her work particularly focuses on translating sleep science into personalised, practical, and culturally responsive tools for real-world settings, for populations such as shift workers and underserved communities. Dr Varma is a co-developer of SleepSync, a personalised sleep-wake management platform designed to support healthier work and recovery patterns in shift workers. Her work demonstrates partnerships with industries and communities, with a strong commitment to co-design, impact, and inclusive health solutions.
Dr Matthew Morrison
Research Fellow
Centre for Human Factors and Systems Science / University of the Sunshine Coast

Athlete sleep as a complex system: A systems thinking approach

3:45 PM - 3:51 PM

Biography

Dr Matthew Morrison is a Postdoctoral Research Fellow at the Centre for Human Factors and Systems Science at the University of the Sunshine Coast. His research focuses on sleep, human performance, and the application of systems thinking approaches to complex problems in sport, health, and safety domains. His work has explored athlete sleep health, high-performance sport systems, and human factors in safety-critical environments. Matthew has experience applying systems science methods to better understand the interacting factors that influence performance, wellbeing, and decision-making in applied settings.
Ms Casey Gilbert
PhD Candidate
Monash University

Sex moderates the association between athlete concussion history and sleep

3:51 PM - 3:57 PM

Biography

Casey is a PhD candidate in Clinical Neuropsychology at Monash University, conducting research within the Facer-Childs ‘Sleep and Performance’ group. Casey’s research explores the role of sleep across all stages of an athlete’s journey with concussion. Within this work, she has a strong interest in ensuring that female athletes and female-dominated sports are well-represented. Alongside her research, Casey is completing clinical training in neuropsychology. She is committed to providing evidence-based and accessible neuropsychological support to people with brain conditions, as well as their families and support networks.

Sleep longitudinally predicts headache/migraine: Insights from the HILDA study

3:57 PM - 4:03 PM

Biography

Dr Dan Sullivan is a Lecturer in Clinical Psychology at Griffith University. His lab focusses on the relationships between sleep and physical and mental health, including headaches, and ADHD. He also leads a program of research to design Australia's first psychology extended scope of practice model with an emphasis on deprescribing hypnotic medicines in the sleep psychology setting (ExPEDiTe Sleep project). Dr Sullivan is a clinical psychologist, Psychology Board of Australia board approved supervisor, and holds the diplomate of behavioral sleep medicine board certification from the US-based Board of Behavioral Sleep Medicine.
