Venue and Travel Information

Conference Description

The Chronobiology GRS provides a unique forum for young doctoral and post-doctoral researchers to present their work, discuss new methods, cutting edge ideas, and pre-published data, as well as to build collaborative relationships with their peers. Experienced mentors and trainee moderators will facilitate active participation in scientific discussion to allow all attendees to be engaged participants rather than spectators.

This year’s meeting will focus on the development of theory and experimental concepts pertaining to the basic science underlying the mechanisms and physiology of biological timekeepers. Moreover, a breakout session will be offered to allow early career scientists to gain insights into the challenges and perspectives of a career in academia and beyond.

Due to limited accommodations at this venue, guest housing is very limited. To request family/guest housing please reach out to your Conference Operations Associate.

Related Meeting

This GRS will be held in conjunction with the "Chronobiology" Gordon Research Conference (GRC). Those interested in attending both meetings must submit an application for the GRC in addition to an application for the GRS. Refer to the associated GRC program page for more information.
