Speaker

Miss Pilar Artiach Hortelano
PhD Candidate
Monash University

Circadian, homeostatic and arousal factors on sleep initiation in adolescents

1:20 PM - 1:32 PM

Biography

Pilar is an international PhD Candidate at Monash University researching sleep and circadian rhythm changes in adolescents. She is particularly interested in circadian phase alignment with sleep-wake behaviour, and how it is associated to different outcomes, such as sleep health and mental health. Altogether, she aims to understand the implications that these major changes in the sleep and circadian systems have for adolescence behaviour and mental health, as a way to identify potential strategies and interventions that will improve and maintain mental health and sleep quality down the track.
Ms Jessica Nicolazzo
Student
Monash University

Sleep and Circadian Timing Changes Across Pubertal Development

1:32 PM - 1:44 PM

Biography

Jessica Nicolazzo is Clinical Psychology PhD candidate at Monash University currently conducting her research in sleep and circadian rhythms over adolescent development. Clinically, she has a keen interest in sleep health education and CBT for insomnia.
Dr Dayna Easton
Research Associate
Flinders University

Is social disadvantage associated with circadian-disruptive light exposure patterns?

1:44 PM - 1:56 PM

Biography

Dr Easton is a Research Associate at Flinders University, where her work focuses on improving the health, well-being, and performance of individuals vulnerable to circadian disruption. Her research interests centre on populations exposed to disruptive light environments, including shift workers and those experiencing social disadvantage. Through her work, she aims to develop practical strategies that support those most at risk.
Miss Helena Stoodley
Student
Woolcock Institute of Medical Research

Skin temperature changes predict driving impairment in individuals with insomnia

1:56 PM - 2:08 PM

Biography

Helena has a background in Medical Science, completing her undergraduate degree at the University of Sydney. She has since undertaken a Master of Research at Macquaire University, conducting her Master's thesis project at the Woolcock Institute of Medical Research. Her research is focussed on thermoregulation and it's link to vigilance.
Ms Laura Hirello
Phd Candidate
Monash University

Paramedic stress responses during a simulated paramedic shift work rotation

2:08 PM - 2:20 PM

Biography

Laura Hirello is a PhD candidate at Monash University. Laura’s research study, project ASAP, looks at how shift work and the resulting circadian rhythm disruption impact paramedics, their work performance, and their decision making. Prior to moving to Australia, Laura worked as an ambulance paramedic for 9 years before moving into healthcare project management and process improvement.
Mr Junyan Zhang
PhD Student
The University Of Queensland

Event-specific ventilatory response to arousal improves arousal threshold estimation

2:20 PM - 2:32 PM

Biography

Junyan (Dave) is a PhD student at The University of Queensland, investigating non-invasive estimation of ventilatory drive and its relationship with pathophysiological characteristics in obstructive sleep apnoea. His work is helping to elucidate the relationship between arousal characteristics and post-event ventilation, while also improving computational endotype estimation.
Assoc Prof Simon Joosten
Associate Professor
Monash University

Impact of polysomnography scoring method on PUP-derived OSA endotypic traits

2:32 PM - 2:44 PM

Biography

Associate Professor Simon Joosten MBBS, BMedSc, FRACP, PhD is a consultant Respiratory and Sleep Medicine physician at Monash Health and Associate Professor at Monash University. His PhD, completed in 2015, investigated the physiological determinants of obstructive sleep apnoea, with a particular focus on upper airway mechanics and positional OSA. His research programme centres on OSA endotyping — characterising individual pathophysiological traits including collapsibility, loop gain, arousal threshold, and muscle compensation — to advance precision medicine approaches for OSA. He has studied clinical applications of polysomnography-derived endotyping methods and has attracted over $32 million in research funding.
