Sian Heder (Siân Heder) is an award-winning American writer and filmmaker born in Cambridge, Massachusetts.
In early 2005, she was one of eight women selected from thousands for the prestigious American Film Institute's DWW (Directing Workshop for Women).
Mother, Heder's first short film as writer and director, won the Grand Jury Award for Best Narrative Short at the Florida Film Festival, a victory which automatically qualified the film for a potential Academy Award nomination. Mother was also selected for the May 2006 Cinéfondation Competition of the Cannes Film Festival, where it won third place in a field of 18 films from around the globe, and the Seattle International Film Festival, where it received the "2006 Short Film: Narrative Special Jury Prize". Since then the film has been further selected to appear in competition at Palm Springs International Festival of Shorts and the British Film Institute's London Film Festival (among others).
In 2010, along with her fellow writers, she won a Peabody Award for her work on the acclaimed U.S. television series, Men of a Certain Age. In 2011 she wrote and directed a short comedy to raise awareness for pet adoption, Dog Eat Dog (A Short Tale) starring Zachary Quinto.
