Report summary

Princeton University Department of Civil and Environmental Engineering in 2024-2026 reads as a 21-PI network with 8 internal PI collaborations. The dominant subject mix is Environmental Science as the leading field (30% of slots across 13 PIs; 13 labels), Environmental Engineering as the leading subfield (11% of slots across 6 PIs; 6 labels), and Flood Risk Assessment and Management as the leading topic (3% of slots across 2 PIs; 2 labels). That is of concern for a 21-PI roster; the strongest pairings may be carrying much of the visible collaboration. The leading PI names are Zhiyong Jason Ren (19.6 weighted works; Microbial Fuel Cells and Bioremediation, Membrane Separation Technologies). The most visible ties are Zhiyong Jason Ren and Jinyue Jiang (7 shared works, weight 4.3). The leading breakdown groups are group 1 with 4 PIs, 4 internal connections, weight 5.5, around Environmental Engineering, Water Science and Technology, Materials Chemistry, led by Zhiyong Jason Ren, Jinyue Jiang, Ryan Kingsbury.
