My research examines the origins and evolution of human semiotic systems, particularly language. Currently, I’m working as a postdoctoral researcher on the Sign Change project. I’m also contributing to several other research projects: studying the evolution of signed languages and their manual alphabets using phylogenetic methods; investigating the composition of early signing communities in schools for the deaf in the United States; and exploring the transmission of and contact among sign languages in the former Soviet Union, including in Georgia and in Tajikistan.
