Report summary

Stanford University Department of Earth System Science in 2018-2020 reads as a 18-PI network with 13 internal PI collaborations. The research center of gravity is Environmental Science as the leading field (41% of slots across 14 PIs; 14 labels), Global and Planetary Change as the leading subfield (18% of slots across 8 PIs; 8 labels), and Atmospheric and Environmental Gas Dynamics as the leading topic (6% of slots across 3 PIs; 3 labels). Overall the pattern is balanced: there is enough structure to identify active groups, while the field mix still leaves room for multiple research identities. The most prominent PIs by weighted works are Robert B. Jackson (14.6 weighted works; Atmospheric and Environmental Gas Dynamics, Plant Water Relations and Carbon Dynamics). The strongest pairings are Marshall Burke and Noah S. Diffenbaugh (4 shared works, weight 3.1). The strongest breakdown groups are group 1 with 6 PIs, 11 internal connections, weight 12.5, around Global and Planetary Change, Health, Toxicology and Mutagenesis, Soil Science, led by Robert B. Jackson, Marshall Burke, Noah S. Diffenbaugh.
