He has published two books of poetry and several chapbooks. His first collection of poems, 20 Poems (2001, ), won praise from Oxford University don John Carey, who compared the poet to W. B. Yeats and from Yale critic Harold Bloom. Several of the poems were Pushcart Prize nominations and were reprinted in major UK magazines, including Agenda, The London Magazine and Stand Magazine.
He published a second book, entitled The Blue Falcon, in 2005 (). His latest book of verse, composed entirely of love poems, is called In the Pool of the Lost Maiden Song.
