It's not everyday you get to meet a Genetically Engineered Life Form (GELF for short), but Red Dwarf fans attending Scifi Wales on 5th September, 2015 can do just that as they get to chat with Steven Wickham, Lister's GELF Bride and the BEGG Chief.

Steven Wickham began his career after leaving college and joining a theatre in education group called Bucket Theatre, touring schools in Buckinghamshire, performing at one occasion for HRH Princess Anne.

For 18 months he played The Baker in Bill Kenwright's memorable national tour of Joseph and the Amazing Technicolour Dreamcoat, and many theatre jobs followed. This includes playing Judas in a national tour of Godspell, Big Jule in Guys and Dolls at the Everyman Theatre, Cheltenham, Reuben Starkadder in Cold Comfort Farm at the Watermill Theatre, Newbury, Oscar Wilde in The Mirror of the Moon at the Edinburgh Festival, and Hiram Otis in the national tour of The Canterville Ghost opposite Ron Moody. He has played in such diverse roles as Hamlet and Abanazar, Mr Peachum and Lady Bracknell.

His has made many television appearances from EastEnders, to Heartbeat from London's Burning to The Bill (four separate times) and from Outside Edge to Casualty (twice). In a 1993 episode (Emohawk: Polymorph II) of Red Dwarf he appeared as a GELF set to marry the leading protagonist Dave Lister and it garnered him some cult notoriety. He became the only character other than the four primary regulars to appear in the title sequence. Nineteen years later he reappeared on Red Dwarf X (episode Entangled), this time playing the chief of a group of Biologically Engineered Garbage Gobblers.

In 2010, he started alongside Rufus Hound in the CBBC sitcom Hounded (CBBC), starring as the character Future Rufus in all 13 episodes, as well as playing a Russian conker champion in an episode of Hotel Trubble (CBBC) and Mr Cobb in the Little Britain spin-off Come Fly with Me with David Walliams and Matt Lucas.

In May 2013 he filmed the role of Santa Claus for the Christmas special episode of Mrs Brown's Boys, the most watched TV programme on Christmas Day.

Steven has appeared in numerous Big Finish Audio dramas, in many guises, most notably Doggles (under the pseudonym of Sam Stevens) and Joseph in the Bernice Summerfield series and Chancellor Valyes in the Gallifrey series.
