Dr. Peter Ranacher
Postdoctoral Researcher
Anthropological Linguistics Group
I am a postdoctoral researcher studying how language and culture evolve across space and time. At ISLE, I coordinate the Glottography Project, an initiative to make geographic language maps accessible to the research community.
Glottography is the first free, open-source platform for mapping the speaker areas of the world’s languages. Developed at the University of Zurich, it currently offers 10,000+ digital language areas derived from over 100 language maps published in scientific research. The data is freely available on GitHub
As part of the TTF project, I focus on building interfaces that allow researchers to access Glottography data in R and Python, while also providing tutorials to help them analyse and visualise the existing data and contribute new data.
