My work focuses on how languages emerge, change, and interact, and how these processes relate to external factors like human agency and ecology. I usually draw upon quantitative methods, and, when observations are not available, computer simulations. Often, I find myself at the intersection of linguistics, archaeology, and genetics. Early in my career, I specialised in Mesoamerican studies, but have since then conducted studies pertaining to many other areas of the world.
