Shockingly, the press release does not mention "author of one of the best Dalek stories of all time".
Ahem. The London Hugo convention is holding a special 1939-styled ceremony, patterned after the first one (8PM on Thursday 14 August 2014 in the ICC Auditorium at ExCeL, should that be relevant to anyone readering this). It'll be hosted by Shearman and Mary Robinette Kowal, a fantasy novelist and Hugo winner herself (in addition to being one of America's leading puppeteers). She's doing a poll on what retro dress design she should wear to the convention - they're rather encouraging coming in costume, and even hired out a period swing band, the Brideshead Ballroom Stompers, for the occasion.
Here's Shearman's biography, anyhow: "Rob Shearman has written four short story collections, and between them they have won the World Fantasy Award, the Shirley Jackson Award, the Edge Hill Readers Prize and three British Fantasy Awards."
"His background is in the theatre, resident dramatist at the Northcott Theatre in Exeter, and regular writer for Alan Ayckbourn at the Stephen Joseph Theatre in Scarborough; his plays have won the Sunday Times Playwriting Award, the Sophie Winter Memorial Trust Award, and the Guinness Award in association with the Royal National Theatre. He regularly writes plays and short stories for BBC Radio, and he has won two Sony Awards for his interactive radio series, ‘The Chain Gang’."
