My research is basically all collaboration with students and colleagues, like the Wisconsin Englishes Project (Tom Purnell and Eric Raimy). Our work combines research and teaching and outreach and it all aims to advance our understanding of speech sounds, how they work as systems, how they are produced and perceived, how they are situated in society and how they change over time. We often draw data from Germanic languages past and present, including contemporary American English.
I also try to understand language contact and language shift, including heritage languages, with Cathy Stafford (Wisconsin), Janne Johannessen (Oslo) and Mike Putnam (Penn State). I work occasionally on morphology, and other issues. Together with Monica Macaulay, my vastly better half, I do a little on phonological, morphological and diachronic issues in Algonquian and Otomanguean languages.
Below are a few projects currently in the pipeline for publication. (Already published material is under "CV".) I'm happy to share unpublished work, especially in exchange for comments and suggestions and lots is already available on Academia.edu.
