He is known as an authority on Beowulf. Neidorf is the author of The Art and Thought of the Beowulf Poet (2022) and The Transmission of Beowulf: Language, Culture, and Scribal Behavior (2017). Neidorf is the editor of The Dating of Beowulf: A Reassessment (2014), which was awarded the Outstanding Academic Title by Choice in 2015, and co-editor (with Tom Shippey and Rafael J. Pascual) of Old English Philology: Studies in Honour of R.D. Fulk (2016). Neidorf maintains that Beowulf was probably composed by a single author in the late 7th or early 8th century AD. For his research on Beowulf, Neidorf was awarded the Beatrice White Prize from the English Association in 2020. In addition to Beowulf, Neidorf has published extensively on other major Old English poems, including Widsith, Maxims, the Finnesburg Fragment, and the Dream of the Rood. His research addresses questions of authorship, interpretation, literary history, and textual criticism. In addition to his traditional philological research, Neidorf has published several large-scale quantitive studies of the corpus of Old English poetry. Neidorf's studies of Beowulf situate the poem in a wide variety of contexts. He explicates its text in relation to Old Norse and Middle High German analogues, medieval traditions concerning the monstrous progeny of Cain, and early English history and culture.
