Reverberation of Active Galactic Nuclei (AGNs) is delivering information of parsec scale structure of galactic nuclei from black hole accretion disks, broad line regions to the inner edge of dusty torus. Reverberation mapping as a powerful tool is not only for AGN physics, but also for cosmology. The workshop is to discuss in detail various outstanding issues in this area, to highlight recent progress and to plan for the future. The main topics are:

1. BLR RM

2. Torus RM

3. RM for co-evolution

4. RM for cosmology
