Methodologically, Gries is a quantitative corpus linguist at the intersection of corpus linguistics, cognitive linguistics, and computational linguistics, who uses a variety of different statistical methods to investigate linguistic topics such as morphophonology, syntax, the syntax-lexis interface, and semantics and corpus-linguistic methodology, as well as first and second/foreign language acquisition. Occasionally and mainly collaboratively, he also uses experimental methods. Much of his recent work involves the open source softwareR. Theoretically, he is a cognitively oriented usage-based linguist in the wider sense of seeking explanations in terms of cognitive processes without being a cognitive linguist in the narrower sense of following any one particular cognitive-linguistic theory. The researchers who have influenced his work most are R. Harald Baayen, Douglas Biber, Nick C. Ellis, Adele E. Goldberg, and Michael Tomasello.
