Historical geographer working at the intersection of GIS, environmental change, and religious landscapes. I use spatial analysis and historical cartography to reconstruct long-term human–environment interactions across China's arid interior and the Tibetan Plateau.

My research examines how societies have shaped and been shaped by water, land, and climate across centuries. I combine historical documents, archival maps, remote sensing imagery, and GIS spatial analysis to transform fragmented textual records into computable geographic data, enabling new perspectives on long-term environmental and social processes.
Three lines of inquiry organize my current work. First, I reconstruct the evolution of hydrographic networks in arid Central and Northwest China over the past century, tracing how irrigation, land reclamation, and climate variability have reshaped the surface water systems of the Tarim Basin, Junggar Basin, and Hexi Corridor. Second, I investigate the spatial structure and historical dynamics of Tibetan Buddhist monasteries across the Plateau, using a georeferenced dataset of over 2,000 institutions to explore the interplay of religion, ethnicity, environment, and political authority. Third, I contribute to collaborative studies on cultural landscapes—including fengshui forests in southern China—that bridge historical ecology and spatial science.
Methodologically, I am committed to making historical geographic information open, reproducible, and interoperable, contributing to the broader project of digital historical geography.
A comprehensive georeferenced dataset documenting over 2,000 Tibetan Buddhist monasteries across the Qinghai–Tibet Plateau. Each record includes geographic coordinates, founding date, sectarian affiliation (Gelug, Kagyu, Nyingma, Sakya, Bon, etc.), and institutional scale. The dataset enables systematic spatial analysis of religious diffusion, sectarian competition, and the environmental contexts of monastic settlement across one of the world's most challenging landscapes.
Two studies drawing on this dataset are currently in preparation: one examining the relationship between Little Ice Age climate fluctuations and shifts in sectarian dominance, and another analyzing the spatial co-distribution of ethnic groups and religious institutions in the Amdo region.
