BIOGRAPHY:

Dylan is a Postdoctoral Research Fellow funded by the National Science Foundation and hosted in the Climate School at Columbia University. He is an archaeologist specializing in remote sensing applications and human-environmental interaction. Dylan's  research interests primarily focus on human responses to hypervariable conditions. In particular, he's interested in how societal actions can influence environmental systems, and how people are impacted by unpredictable climatic conditions.  Most of Dylan's work focuses on island and coastal regions and makes use of geospatial methods (e.g., remote sensing, GIS, network analysis) in conjunction with archaeological, ethnographic, and paleoecological data. Ultimately, his work seeks to further our understanding of how people interact with and are affected by their environment. Dylan's ongoing research seeks to understand the role that socioeconomic strategies play in long-term ecological change across landscapes. Specifically, his postdoctoral research focuses on how ecological systems are impacted by foraging, pastoralism, and agricultural activities. Dylan earned his Ph.D. in Anthropology in 2022 from Penn State. He also has an MA (2018) and BS (2017) in Anthropology and a BA (2017) in Geography from Binghamton University. Dylan currently serves on the Editorial Board of Archaeological Prospection as an Early Career Researcher.
