Report summary

Stanford University Department of Earth System Science in 2015-2026 reads as a 55-PI network with 91 internal PI collaborations. The research center of gravity is Environmental Science as the leading field (38% of slots across 41 PIs; 41 labels), Global and Planetary Change as the leading subfield (13% of slots across 18 PIs; 18 labels), and Marine and coastal ecosystems as the leading topic (3% of slots across 5 PIs; 5 labels). That is promising: collaboration is not just one large hairball, and the leading breakdown groups cover 24 PIs across distinct clusters. The most prominent PIs by weighted works are Scott Fendorf (40.5 weighted works; Heavy metals in environment, Arsenic contamination and mitigation); Marshall Burke (39.6 weighted works; Air Quality and Health Impacts, Climate Change and Health Impacts). The strongest pairings are Marshall Burke and Noah S. Diffenbaugh (19 shared works, weight 11.8). The strongest breakdown groups are group 1 with 10 PIs, 9 internal connections, weight 46.5, around Global and Planetary Change, Environmental Engineering, Ecology, Evolution, Behavior and Systematics, led by Marshall Burke, David B. Lobell, Noah S. Diffenbaugh.
