ASTI is a capacity-building project to establish UiT as a centre of excellence for research into seasonal timekeeping mechanisms. This fills a strategic gap in chronobiology research worldwide, and is an excellent fit to UiT as the world’s northernmost research university.
ASTI will combine excellence in genome-enabled approaches to define the genetic basis of seasonal timer mechanisms (transcriptomics, comparative genomics, epigenomics, gene targeting), with state of the art approaches to in-vivo analysis of seasonal changes in physiology and behaviour (microdialysis, metabolomics, endocrinology, telemetry), and integration of complementary approaches through data processing capacity (mathematical network modelling, database management and data sharing).
ASTI will cover three overlapping themes spanning both basic and applied / societally important aspects: ‘Core seasonal timer mechanisms’, ‘Comparative seasonal chronobiology’ and ‘One seasonal health’.
ASTI will enhance awareness and understanding of the importance of seasonal timekeeping mechanisms for the health and wellbeing of humans and animals living in the Arctic region.
The centre project period is 1st April 2021 to 31st March 2025. The centre director is Professor David Hazlerigg and deputy director is Dr. Shona Wood. The centre is based within the research group Arctic chronobiology and physiology at the Department of Arctic and Marine biology.
