Speaker

Dr Charlotte Gupta
Senior Postdoctoral Research Fellow
Appleton Institute

Can breaking up sitting during dayshifts and nightshifts improve sleep?

1:30 PM - 1:35 PM

Biography

Charlotte is a senior postdoctoral research fellow at the Appleton Institute at Central Queensland University and completed her PhD in 2020. Charlotte’s research investigates the optimal timing of sleep and nutrition, particularly for those working non-standard hours such as shiftworkers. Charlotte is an emerging research leader in the field of chrononutrition, and her research on the impacts of meal timing at night on work performance has informed practice and policy for shiftworkers.
Miss Zohreh Sajadi Hezaveh
Student
University of Sydney

Dinner timing and post-dinner-to-bedtime window in relation to sleep

1:35 PM - 1:40 PM

Biography

Zohreh Sajadi Hezaveh is a PhD candidate at the University of Sydney, researching how meal timing and chronotype influence sleep and metabolic health. Supervised by Dr. Chin Moi Chow, she combines clinical and public health approaches to inform chronobiology-based lifestyle strategies.
Dr Elizabeth Machan
Senior Lecturer
University of Sydney / The Woolcock Institute

A novel dietary protocol to manage symptoms of hypersomnolence

1:40 PM - 1:45 PM

Biography

Dr Machan is an accredited exercise physiologist and nutritionist. She has extensive experience in designing and implementing nutritional and lifestyle interventions for sleep disorders. She is a full time academic at the University of Sydney in the Discipline of Exercise and Sport Science and is an honorary affiliate of the Woolcock Institute where she completed her PhD in obesity management for patients with OSA. The current protocol is funded by the AASM and is a unique approach to managing symptoms of narcolepsy and idiopathic hypersomnia.
Dr Suman Dhaka
Assistant Professor
IIT Jodhpur

Sleep deprivation effects on response inhibition: behavioral and ERP findings

1:45 PM - 1:50 PM

Biography

Dr. Suman Dhaka is an Assistant Professor at the School of Liberal Arts, IIT Jodhpur. Her research explores fundamental and applied questions at the intersection of brain and behavior, focusing on cognitive processes, neural dynamics, and adaptability. She integrates EEG, brain stimulation, and computational modeling to advance understanding across cognitive neuroscience, sleep and cognitive well-being interventions, and neuromodulation strategies for diverse populations. Dr. Dhaka has successfully led R&D projects funded by ICMR, ICSSR, and DST, and collaborates actively with institutions such as the University of Pennsylvania, AIIMS, and IITs.

Miss Sian Wanstall
Phd Candidate
Flinders University

Causes and consequences of paramedic fatigue and sleep loss

1:50 PM - 1:55 PM

Biography

Sian is a registered paramedic and PhD candidate at Flinders University. Her PhD work is a systems-thinking informed, qualitative exploration of the experience of fatigue and sleep loss in Australian paramedics to inform meaningful interventions.
Prof Alister Neill
Clinical Director, Department of Medicine
Wellsleep / University of Otago

Fatigue related crash trends in Aotearoa/ New Zealand. post

1:55 PM - 2:00 PM

Biography

I am a Professor in the Department of Medicine, Clinical Director WellSleep. I also work as a Respiratory & Sleep Physician at Wellington Hospital (CCDHB). My research interests include: the epidemiology and pathophysiology of obstructive sleep apnoea (OSA), its relationship to cardiovascular disease, sleep health disparity, new sleep health technologies, home non-invasive ventilation (NIV). Currently leading collaborative research into the respiratory impact of neuromuscular diseases, physiological OSA traits and novel treatments for OSA.
Dr Madeline Sprajcer
Senior Lecturer
CQ University

Co-designing educational resources to reduce fatigue-related driving risk in parents

2:00 PM - 2:05 PM

Biography

Madeline is a Senior Lecturer at CQUniversity’s Appleton Institute, with a research focus on sleep, non-standard working arrangements, fatigue detection technology, and fatigue risk management.
Mr Andrew Kidcaff
PhD Candidate
Queensland University of Technology

Understanding sleep behaviour in esports and predictors of sleep quality

2:05 PM - 2:10 PM

Biography

Andrew holds undergraduate degrees in exercise science and psychology, providing a strong foundation in both human physiology and behaviour. He is currently a higher degree research student and is investigating the relationship between sleep behaviour and cognitive performance outcomes in esports players. Andrew's research aims to translate sleep science principles to optimise player performance and recovery, and advance evidence-based approaches to support cognitive functioning in competitive environments.
Dr Jordan Fox
Lecturer In Exercise Science
University Of South Australia

Consequences of low sleep regularity in athletes: A scoping review

2:10 PM - 2:15 PM

Biography

Dr Jordan Fox is an early career academic lecturing in Exercise Science at the University of South Australia. Her research focuses on the interaction between training and game demands and sleep to optimise health and performance-related outcomes for athletic populations. She is an accredited Exercise Scientist and Sports Scientist and has published over 60 peer-reviewed manuscripts.
Ms Anna Mullins
Research Fellow
School of Psychological Sciences faculty of Medicine Nursing and Health Sciences / Monash University

ANS activity during habitual sleep is associated with impaired cognition.

2:15 PM - 2:20 PM

Biography

Anna completed her PhD at The University of Sydney and the Woolcock Institute of Medical Research. As a registered poly-somnographic technologist (RPSGT) her technical expertise is in physiological signal measurement, analysis and interpretation. Anna’s research interests intersect sleep-wake physiology, psychology, and environmental factors influencing cognitive and emotional health. Current research investigates the relationship between sleep, cognition and risk for neurodegeneration via brain and biological-based biomarkers. This research measures sleep in multiple dimensions across central and autonomic nervous system activities during single-night, in-laboratory and at-home assessments of habitual sleep to develop personalised therapeutic targets for poor sleep quality.

Dr Timothy Howarth
Post-doctoral Researcher
Darwin Respiratory and Sleep Health

Comparison of the GPSS between Indigenous and non-Indigenous Australian patients

2:20 PM - 2:25 PM

Biography

Dr. Timothy Howarth is a leading researcher in respiratory and sleep medicine, with a particular focus on chronic respiratory diseases, novel methods for sleep apnoea severity estimation, and sleep health in Australia. His work spans epidemiology, diagnostic advancements, health technology, treatment optimisation, and healthcare disparities, with a strong emphasis on improving health outcomes for Indigenous Australians and remote communities. Through his research, he seeks to develop more precise diagnostic tools, culturally adapted treatment strategies, and innovative healthcare delivery models that address the unique challenges faced by these populations.
