We are organizing the Second Guangzhou International Workshop on Mathematical Imaging at Sun Yat-sen University in Guangzhou, China, which will take place on December 14-15, 2013. The objective of this workshop is to bring international experts in imaging together to present their recent research work, to exchange ideas, and to develop new visions for the future of the area. The workshop will provide an opportunity for participants to share information and experiences, and a platform for their research collaboration. On behalf of the organizing committee, I would like to invite you to present a 30 minute invited lecture in the workshop. There will be no registration fee for the workshop and we will cover your local expenses including accommodation, meals and a banquet during the workshop.
