Barbara Southcott has been the main make-up designer for Doctor Who since The Runaway Bride.
Though others have occasionally done a few episodes, particularly the double banked "Doctor-lite" ones, she has designed by far the most episodes from series 3 - 5.
Prior to her work on Doctor Who, she worked with producer Phil Collinson, lead actor Bill Paterson and a host of Doctor Who-related guest stars including Paul McGann as the make-up designer on Sea of Souls.
One of her very earliest credits is as a hairstylist on the episode "Benares, January 1910" of The Young Indiana Jones Chronicles. This makes her one of the few Doctor Who crew members also to have worked in the Indiana Jones franchise.
Works include The Chatterley Affair, Sea of Souls, Born and Bred, Rancid Aluminium, Looking After Jo Jo, Face, Hamish Macbeth, Princess Caraboo, Wycliffe, The Young Indiana Jones Chronicles, Blame It on the Bellboy, Hedd Wyn, Fools of Fortune, Maigret, Return to Treasure Island
