Dr. Kingcaid is a specialist in nineteenth- and twentieth-century French prose fiction, with a special interest in psychoanalysis and narrative theory. She has published over a dozen articles and delivers regular conference papers in these fields.

Her 1992 book, Neurosis and Narrative: The Decadent Short Fiction of Proust, Rachilde, and Lorrain, has been praised as "excellent," "imaginative," and "enlightening"; the Revue d'histoire littéraire de la France cited it as opening "new methodological and interpretative perspectives" on the fiction of late 19th-century France.

Dr. Kingcaid has received numerous grants from Saint Mary's College in support of her teaching and research initiatives; she is currently editing a collection of essays on mothers' deaths in French literature and is writing a book on the "autofiction" of French novelist and literary critic, Serge Doubrovsky.

She particularly enjoys teaching Intermediate French, Transition to French Literature, courses in the French novel, and she frequently supervises independent literary studies.
