Castillo was born and raised in Louisiana, but moved to Portugal after marrying Jose Federico Perez Castillo in 1969. She initially worked at Oporto University from 1978 to 1996. During this period she published as Susan Perez Castillo. She is fluent in Portuguese, Spanish and French, which has influenced her later work on the multilingual literatures of the Americas.
Teaching career
After serving as a lecturer in English at Oporto, Castillo became Fernando Pessoa University's Vice-Principal for International Relations. Shortly afterwards, she moved to the University of Glasgow as a lecturer, shortly being promoted to Reader and then assuming the John Nichol Professorship of American Literature. Subsequently, she moved to King's College to assume the Harriet Beecher Stowe professorship.
Writing career
Castillo's research interests range widely, but have always included a focus on the trauma of the colonial encounter and the margin in American writing: her first edited collections in Portugal are all concerned with questions of American identity, particularly in a multilingual context. Native American history and contemporary Native literature have always been a strong feature of her work, leading to the collection Native AmericanWomen in Literature and Culture, but also informing a more general interest in understanding both sides of the colonial moment. More recently, she has produced expansive historical work that re-visions the early American context. Her co-edited anthology The Literatures of Colonial America was described as a book that may "model a new kind of early American studies that reads beyond the U.S. nation and change the field's object of study.", while her monograph American Literature in Context to 1865 raised a series or questions for one reviewer: "How can we bring scholarship that challenges the U.S.-based framing of early America into introductory texts? How can we loosen the grip that United States nationalism has on colonial America while still engaging historical frameworks? Can curriculum committees, publishers, and casual readers be convinced that early American literature should be hemispheric, multilingual, and multidisciplinary?".
Poetry
Castillo has published three collections of poems and describes her writing as being focused on "Nature; the wonders and the weirdness of family; sounds and accents and voices; incidents when I travel; the language of children, which is wonderfully direct and uncluttered with stale metaphors; old photographs; songs; paintings."
Marriage
and Susan Castillo married in 2011: Street died the year after following a fall. The Guardian obituary described their life together "in an oast house near Tunbridge Wells, which they restored together. Outside work, Jonathan was a book-lover and film fanatic, particularly fond of French New Wave cinema and classic Hollywood film noir. One of the founding members of the Campaign for Real Ale, he enjoyed nothing more than sipping a pint of Harveys at his village pub and revelled in the peace and solitude of his home, where deer would wander into the garden from the nearby forest."
