Conference Description

The Chromosome Dynamics GRC is a premier, international scientific conference focused on advancing the frontiers of science through the presentation of cutting-edge and unpublished research, prioritizing time for discussion after each talk and fostering informal interactions among scientists of all career stages. The conference program includes an array of speakers and discussion leaders from institutions and organizations worldwide, concentrating on the latest developments in the field. The conference is five days long and held in a remote location to increase the sense of camaraderie and create scientific communities, with lasting collaborations and friendships. In addition to premier talks, the conference has designated time for poster sessions from individuals of all career stages, and afternoon free time and communal meals allow for informal networking opportunities with leaders in the field.

Deciphering the regulation and functional consequences of chromosome dynamics is essential for our understanding of cellular function, organism survival and development of disease. Having evolved from the study of inherited traits in pea plants, the field of chromosome biology now encompasses a large number of model systems in all three domains of life and exploits approaches ranging from cell-, molecular- and structural biology to biophysics and computational modelling. The conference aims to bring together scientists from all areas of chromosome research to share new results and ideas. By gathering an international and diverse group of researchers, the conference will promote collaborations, accelerate young scientists’ career advancement and direct future development of the field.

Related Meeting

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