Darren Cullen is a London-based professional graffiti artist who is commonly known by the tag name SER. Cullen emerged as an artist from the British graffiti art scene in the early 1980s.
Cullen grew up in Croydon where he became active in the graffiti and street art scene in 1983. His current graffiti name "Ser" was originally a crew name, which stood for "South East Rockers" – an unorganized crew name used by other graffiti artists in the south east area of London. When other graffiti artists stopped using the name "Ser", Cullen adopted the name as his own.
In July 2012 London Cullen spoke to Rebecca Cafe of BBC News and said he was confused as to why the graffiti walls in East London were all of a sudden being cleaned. The walls in East London "the mecca of graffiti" had been there for years, but with the Olympics about to start the authorities wanted to clean the streets.
In November 2013, in an interview with The Economist, Cullen gave his view on why graffiti had become respectable. Cullen went on to say that graffiti had evolved due to a number of factors. Magazines and documentaries documenting good graffiti art and spray paint had been produced especially for graffiti. The paint now gave the artist more control over his artwork, he said.
