I am interested in the areas of syntax and morphology, including general theoretical issues, as well as issues relating to particular languages. I also work on language change. My research has focused on Germanic languages, in particular the Scandinavian ones and Pennsylvania German, but a number of my publications have a wider comparative aim. Among other things, I have worked on noun phrases, complementation, agreement, the role of morphology in theories of syntax and I have argued against specific claims in the literature of 'degrammaticalisation' in Germanic languages. Most recently, I have considered how morpho-syntactic change can be accounted for within different theoretical architectures.
With colleagues in Manchester, Oslo and Wuppertal, I have a project on early Germanic noun phrases for which we have receievd network funding from the Nansen foundation in Norway.
Jointly with David Denison I have recently worked on a project entitled Germanic possessive -s : an empirical, historical and theoretical study project page funded by the AHRC.
I have run an ESRC funded project on Pennsylvania German as spoken in Waterloo County: Modelling syntactic change in Pennsylvania German.
