Biography

Sveta Postnova is an Associate Professor at the University of Sydney leading the Circadian Physics Sleep Dynamics Group within the School of Physics. Her research interests focus on brain dynamics and its interactions with bodily systems and environmental factors. Key topics include sleep-wake cycles, cognition, and circadian rhythms. She employs methods from physics, mathematics, and data science to develop quantitative models of brain dynamics, which aim to unify experimental data and explain underlying mechanisms. Additionally, Sveta designs health monitoring tools and strategies for disease prevention. Her work addresses complex biological systems, particularly focusing on the health consequences of circadian rhythm misalignment. The group also investigates sleep dynamics, utilizing neural modelling techniques to explore the transition between wakefulness and sleep. Sveta has been involved in various significant grants aimed at understanding the circadian system and its implications for health, as well as collaborations with Qantas on projects related to health and wellness during travel.
