Moduli spaces (MOD) Organised by Farkas, Reid and Shepherd-Barron Moduli spaces of different geometric structures is a Leitfaden covering many different areas of algebraic geometry, and linking it to other branches of math (differential and symplectic geometry, topology, number theory, theoretical physics and so on). There have been several important recent developments on the most classical moduli spaces A_g for Abelian varieties (Shepherd-Barron, Grushevsky and Lehavi) and M_g for curves of genus g (Farkas), K3_g moduli of K3 surfaces (Gritsenko, Hulek and Sankaran), applications of derived categories (Bridgeland). The topic also includes moduli spaces of bundles or connections over a Riemann surface, the Hilbert schemes of points on surfaces, G-Hilbert schemes and the McKay correspondence. Moduli spaces will be a component of many other WAG07-08 activities, with an active period in Jun--Jul 2008 leading up to a workshop planned for Mon 7th--Fri 11th Jul Confirmed participants: Corti, Farkas, Reid, Shepherd-Barron, Targetted: Alexeev, Bertram, Bridgeland, Craw, Ekedahl, Erdenberger, Faber, Fantechi, Gritsenko, Grojnowski, Gross, Grushevsky, Haiman, Harris, Hassett, Hitchin, Hulek, Huybrechts, Kirwan, Langer, Lehavi, Mukai, Newstead, Popescu, Salvati Manni, Sankaran, Starr, Thomas, Vakil, Verrill, Viehweg, Zuo, de Jong, van Straten,
