538 | Studying Shape: From Human Histories to Earth Processes
In this week’s episode, hosts Kelly Wang and Scott Walters interview Sorcha Rountree, a PhD student in Earth Science, about their journey from archaeology to geology and what studying ancient skull shapes can tell us about identity in the past.
Sharing insights from their MA research on cranial modification in Prehispanic Peru, Sorcha explains how geometric morphometric methods help researchers study shape and cultural practices, what their results revealed about identity and social status, and how their interdisciplinary background opened the door to a new path in Earth Science.
