Miller's first book, ''The Poem's Two Bodies: The Poetics of the 1590 "Faerie Queene"'' (1988), analyzes the relationship between Spenser's aesthetic structure and the political ideology of the
Tudor period. His 2003 work,
Dreams of the Burning Child, examines the theme of filial sacrifice across works by
Virgil,
Shakespeare, and
Charles Dickens. In a 2018 article in the Stanford Humanities Center's
Arcade, scholar Roland Greene characterized Miller's critical approach as a "criticism of costs," noting its ethical attention to the religious and historical dimensions of social order. He is a General Editor of
The Collected Works of Edmund Spenser, which is under contract to be published by
Oxford University Press. He served as the editor of
The Spenser Review from 2012 to 2017. == Selected works ==
