Stefan Th. Gries (['ʃtɛfɐn 'tʰoːmɐs 'ɡʁiːs]) is Professor of Linguistics in the Department of Linguistics at the University of California, Santa Barbara (UCSB), Honorary Liebig-Professor of the Justus-Liebig-Universität Giessen (since September 2011),^[1] and since 1 April 2018 also Chair of English Linguistics^[2] (Corpus Linguistics with a focus on quantitative methods, 25%) in the Department of English^[3] at the Justus-Liebig-Universität Giessen.

Gries earned his M.A. and Ph.D. degrees at the University of Hamburg, Germany in 1998 and 2000 and his Habilitation/Venia Legendi at the University of Marburg in 2024.^[4] He was at the Department of Business Communication and Information Science of the University of Southern Denmark at Sønderborg (1998–2005), first as a lecturer, then as assistant professor and tenured associate professor; during that time, he also taught English linguistics part-time at the Department of British and American Studies of the University of Hamburg. In 2005, he spent 10 months as a visiting scholar in the Psychology Department of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, before he accepted a position at UCSB, starting November 1, 2005.^[5] Gries was a visiting professor at the 2007, 2011, 2013, 2015, and 2019 LSA Linguistic Institutes at Stanford University,^[6] the University of Colorado at Boulder,^[7] the University of Michigan, Ann Arbor,^[8] the University of Chicago,^[9] and the University of California, Davis.^[10] He was also a Visiting Chair (2013–2017) of the Centre for Corpus Approaches to Social Science at Lancaster University and the Leibniz Professor (spring semester 2017) at the Research Academy Leipzig of the Leipzig University.^{[11], [12]}

Methodologically, Gries is a quantitative corpus linguist at the intersection of corpus linguistics, cognitive linguistics, and quantitative linguistics, who uses a variety of different statistical methods to investigate linguistic topics such as morphophonology (the formation of morphological blends),^[13] syntax (syntactic alternations), the syntax-lexis interface (collostructional analysis),^[14] and semantics (polysemy, antonymy, and near synonymy in English and Russian)^[15][16] and corpus-linguistic methodology (corpus homogeneity and comparisons, association and dispersion measures, n-gram identification and exploration, and other quantitative methods), as well as first and second/foreign language acquisition ^[17][18] and corpus linguistics and legal interpretation.^[19][20] Occasionally and mainly collaboratively, he also uses experimental methods (acceptability judgments, sentence completion, priming, self-paced reading times, and sorting tasks). As per five of the last six books he has written and the last book he co-edited, much of his recent work involves the open source software R.

Theoretically, he is a cognitively oriented usage-based linguist (with an interest in Construction Grammar) 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.
