I teach both graduate and undergraduate courses in syntax and semantics. At the undergraduate level, I occasionally teach LING 3430, an undergraduate introduction to semantics that is required for the major, and a multi-section cross-listed course that I helped to create, LING/CLAS 1010 (The Study of Words), an introduction to the development and structure of the English vocabulary that focuses on words of Latin and Greek origin. At the graduate level, I teach an MA-level introduction to semantics and pragmatics (LING 5430) that is required for the MA degree in Linguistics, a doctoral-level required introduction to syntactic analysis (LING 6450) and doctoral-level courses in syntax and semantics (LING 7420, 7430 and 7800), all of which focus on construction-based approaches. My current course websites require access, but the list in the right sidebar provides a sample of my older, public sites (they look very primitive now). In addition to classrooom teaching, I advise doctoral students, and have graduated 8 PhD students since 1999. Among my former advisees are , an associate professor of English at Stephen F. Austin State University, , a post-doctoral researcher in the Psycholinguistics Group, Department of Computational Linguistics and Phonetics, Saarland University, Germany ( was Les's co-advisor), and Kevin Gould, language arts analyst at IXL Learning, Inc.
