I am a senior researcher in the Institute for the Interdisciplinary Study of Language Evolution at the University of Zurich, where I lead the Quantitative Diachronic Linguistics group and am Principal Investigator of the Swiss National Science Foundation grant “Evolving Paradigms: Quantitative and Computational Approaches to Analogical Change.”
Broadly speaking, my research interests revolve around language change.
I am interested in the pressures that interact to shape the synchronic profiles of languages, and use a wide range of tools in my approach to these issues.
My research program is twofold: on one hand, I ask how we can refine our understanding of relatedness among languages, using tools from computational biology, deep learning, and other probabilistically oriented fields.
Second, with representations of phylogenetic relatedness in hand, I attempt to learn more about the dynamics of language change across linguistic features and across different sociolinguistic, environmental and cultural milieux.
A large part of my work involves developing probabilistic models that are flexible enough to address a wide range of questions of interest to diachronic linguists and linguists more generally.
