Welcome to my homepage. I study and teach about speech sounds and language change, often drawing data from historical and contemporary Germanic languages. Beyond that, I have the privilege of editing Diachronica: International journal for historical linguistics. With Tom Purnell and Eric Raimy, I'm writing Modularity in phonology, with Patrick Honeybone I'm editing the Handbook of Historical Phonology for Oxford University Press (see here for more), and with Rob Howell and Paul Roberge, I am working on the Cambridge History of the Germanic Languages. more . . .
