How do infants acquire language so efficiently?
I'm studying this question from three angles.

The social environment
The social environment plays an important role for language learning. But which elements compose this environment, how are they connected, and through which mechanisms do social cues boost language learning? I focus on disentangling the role of different social cues like contingency or reference by using techniques like gaze-contingent eye-tracking.

The acquisition of speech sounds
Acquiring the speech sounds of one's native language is an essential building block of language acquisition. But which factors influence how infants acquire their native phonological system?
Language-specific experience interacts with language-general abilities to shape infants' developing speech perception. This is a topic I have investigated in my PhD thesis (part of which I've also tried to dance.)

The whole is more than its parts: Meta-analysis
I am also interested in reproducibility and open science. What a single study can tell us is limited, but luckily there are techniques to quantitatively synthesize data across studies. I am part of the Metalab project, an open-source database of meta-analyses of infant language acquisition. In the context of improving scientific practices, I also took part in #barbarplots, a campaign raising awareness for more appropriate data visualization.

Finally, I am writing for CogTales, a blog on research(er life) from the perspective of young female cognitive scientists.
