Dr. Sam Chambers is an environmental geographer and biometeorologist whose research examines how environmental conditions, infrastructure, and governance shape human and ecological exposure, mobility, and survival. His work integrates spatial analysis, environmental modeling, remote sensing, and counter-forensic approaches across border studies, climate and health, and landscape ecology. He has investigated migrant mortality and environmental exposure in militarized borderlands; physiological risks associated with extreme heat, terrain, and uneven access to resources; and the effects of land-use change, energy development, and transportation infrastructure on wildlife movement and habitat connectivity. Across these areas, his research connects physical environmental processes with their social and political contexts to understand how landscapes become hazardous, fragmented, or difficult to inhabit.
