This is the "official biography" that my publishers use:

She has published over forty books, winning nine World Fantasy Awards, the Mythopoeic Award, the Bram Stoker Award, and placing on the short lists for the Tiptree and Shirley Jackson Awards. She received the S.F.W.A. Solstice Award in 201o for "outstanding contributions to the speculative fiction field as a writer, editor, artist, educator, and mentor." Her work has been translated into French, German, Spanish, Italian, Czech, Russian, Turkish, Korean, and Japanese. She has served on the boards of the Interstitial Arts Foundation and the Mythic Imagination Institute (U.S.), and is currently a member of the advisory board for the Sussex Centre for Folklore, Fairy Tales, and Fantasy at the University of Chichester (U.K.).

Okay, that's the formal professional biography.
