G2 geometry is an exciting and rapidly developing research area internationally, with links to topics across mathematics and theoretical physics, including geometry, topology, analysis, string theory and M-theory. This workshop aims to address some of the key open problems in the area by bringing together a diverse range of geometry researchers from around the world, with a particular focus on young and early career researchers, so that they may discuss their results and explore novel approaches, as well as strengthen and form new collaborations.
