Expert Witness No.1093





The application of the principles and methods of linguistics to the language of legal proceedings and documents.


Forensic Semantics: Analysis of and expert opinion on the meaning of words, phrases, clauses,
paragraphs, etc., in legal, personal, and commercial communication (e.g., contracts, wills, cases of
copyright infringement).

Forensic Stylistics: Analysis of the syntax, style, word choice, spelling, punctuation, rhetorical strategies, and other features of anonymous, disputed, or forged documents (including e-mails); expert opinion on (i) authorship and/or characteristics of author; (ii) evidence for/against plagiarism.


My original, multi-dimensional approach to stylistic analysis goes beyond language elements to
include rhetorical strategies and intellectual breadth/depth, thus enabling me to identify a wide
range of stylistic similarities and differences.


A professional lifetime devoted to the analysis of language and the understanding of language variation and stylistic nuance:

Doctoral dissertation (University of Chicago, 1973): an analysis of code-switching (i.e., variation in the speaking style of an individual).  Relevant to authorship/plagiarism cases.

Undergraduate and graduate studies of English syntax, semantics, and style; in-depth understanding of language structure: (1) identify the vocabulary and grammatical choices that characterize an individual writer’s style. (2) Recognize errors that no native speaker would make and thus determine whether a document has been written by a speaker of a foreign language.  Relevant to authorship, plagiarism/copyright, and contract interpretation cases.

Twelve years of teaching English linguistics and composition (including graduate seminars in stylistics and in the structure and process of written language): (1) the correlation between a writer’s level of education and his/her deviations from Standard English; (2) the particular locutions favored by individual writers.  Relevant to authorship/plagiarism cases.

Twenty years as a corporate speechwriter/ghostwriter: deep theoretical and practical understanding of the nature and variation of individual style. Relevant to authorship/plagiarism cases.

Examination/analysis of thousands of student papers, corporate publications, and countless other written documents: formulate expert opinion on plagiarism and anonymous or disputed authorship by judging whether particular words, phrases, or other linguistic elements could occur by chance in two separate documents - or whether the documents are the product of the same hand.   Also relevant to interpretation of contracts, wills, laws, regulations.

Extended practice in transcription (basic linguistics courses, doctoral theses, speechwriting); qualified to evaluate the accuracy of transcriptions (from handwriting to typing and from audio to writing).
