My research interests are in second language acquisition, linguistic theory and  theoretical and experimental syntax. I currently focus on combining linguistic and computational modeling of learner trajectories in big learner corpora.

Current research topics: linguistic typology and learnability in L2, input processing instruction, child L2 acquisition, linguistic complexity in L2 development

I am one of the people who set up and run the  Cambridge Bilingualism Network, a public engagement initiative promoting the linguistic and cognitive advantages of bilingualism. I am also the founding  Editor of Languages, Society and Policy (LSP), a journal aiming to connect research in linguistics and languages with policy making.
