CASTL operates as a loose confederation of about two dozen researchers with PhDs in linguistics and about a dozen PhD students at any given time, with various research projects involving different constellations of researchers and national and international networks of collaborators.
The syntax groups are working on several topics at the interfaces of syntax with other systems, in particular morphology and semantics. On the empirical side, we are deeply committed to comparative work, and to an integration of morphological, semantic and syntactic patterns. Our research includes a range of subprojects, including work on Bantu languages, Nordic dialect syntax, lexical semantics, and spell-out.
In phonology, CASTL researchers are exploring a phonology which is strictly separated from phonetics ("substance-free") and where much of the structure is emergent from general principles rather than given by Universal Grammar ("minimalist"). This research is divided into two main subprojects: one on feature theory (the internal representation of segments) and one on prosodic theory (how segments relate to one another).
The acquisition researchers are exploring children's sensitivity to micro-variation in the input within a new approach to language acquisition and change - based on micro-cues.
