Paul Armstrong's work focuses on the relations between neuroscientific research on consciousness and cognition and literary theories of reading and narrative.
His most recent book is Stories and the Brain: The Neuroscience of Narrative (Johns Hopkins UP, 2020; Arabic, Chinese, and Korean translations in progress). This neuro-phenomenological analysis of our embodied cognitive capacity to tell and follow stories is a sequel to his book How Literature Plays with the Brain: The Neuroscience of Reading and Art (Johns Hopkins UP, 2013; Arabic and Slovenian translations; Chinese translation in progress). He has also edited a special issue entitled "Cognitive Modernisms" of the journal Mfs (Modern Fiction Studies), vol. 68, no. 4, Winter 2022.
His current project asks how our species' embodied cognitive equipment allows authors and readers to interact collaboratively across historical distance. An essay entitled "The Neuroscience of Literary Time-Travel: How Literary Works Cross Historical Distance" has been published by Narrative, vol. 31, no. 3, October 2023.
His other books include The Phenomenology of Henry James (U of North Carolina P, 1983), The Challenge of Bewilderment: Understanding and Representation in James, Conrad, and Ford (Cornell UP, 1987; e-book 2018), Conflicting Readings: Variety and Validity in Interpretation (U of North Carolina P, 1990; Spanish and Arabic translations), and Play and the Politics of Reading: The Social Uses of Modernist Form (Cornell UP, 2005). The opening chapter of Conflicting Readings was awarded the William Riley Parker Prize for an Outstanding Article in PMLA . His chapter on Nostromo in The Challenge of Bewilderment won the Twentieth Century Literature Prize in Literary Criticism.
Armstrong has also prepared several critical and scholarly editions of major modern novels. His Norton Critical Edition of E. M. Forster's novel A Passage to India was published in 2021. He previously published two Norton Critical Editions of Joseph Conrad's novella Heart of Darkness (5th ed., W. W. Norton, 2017; 4th ed., W. W. Norton, 2006). The revised edition features a newly established text based on the first English book publication as well as a substantially revised critical apparatus. He also produced a Norton Critical Edition of E. M. Forster, Howards End (W. W. Norton, 1998).
Armstrong has also completed a scholarly edition of Henry James's posthumously published, unfinished novel The Ivory Tower for the Cambridge University Press series of James's collected fiction (in press, anticipated publication 2025). He is currently at work on a scholarly edition of Howards End for the Cambridge University Press edition of Forster's fiction.
Before coming to Brown as Dean of the College in 2001, Armstrong was founding Dean of the College of Arts and Sciences at SUNY-Stony Brook and Humanities Dean at the University of Oregon. As Dean of the College at Brown, Armstrong launched the First-Year Seminar Program and served on the Committee on Slavery and Justice. He has also taught at the University of Virginia and Georgia Tech and has been a visiting professor at the University of Copenhagen and the Free University of Berlin. He is a member of the visiting faculty of the Institute for Doctoral Studies in the Visual Arts (IDSVA), and he is on the Affiliated Faculty of the Robert J. and Nancy D. Carney Institute for Brain Science at Brown.
Armstrong has held fellowships from the Alexander von Humboldt Foundation and the National Endowment for the Humanities. He also received a grant from the Teagle Foundation to chair an inter-institutional working group that wrote a white paper on "The Open Curriculum: An Alternative Tradition in Liberal Education." Past president of the Joseph Conrad Society of America, Armstrong has been a member of the editorial boards of the Henry James Review, Conradiana, and Modern Fiction Studies.
