David Roach is an extremely prolific inker for Doctor Who Magazine comic strips. He continued to be arguably DWM's "house inker" into 2011, having been active with DWM since his first story, 2002's Oblivion. Though prolific with DWM, he hasn't worked on any other DWU publication, save for the story Sunscreen in Panini's 2007 Storybook. He has never pencilled any story for Doctor Who, though he has a fairly extensive list of pencil jobs outside the DWU. Within the pages of DWM, he has perhaps partnered with penciller Mike Collins most often, but has also significantly paired with DWM's other long-term penciller, Martin Geraghty.
