Report summary

For Princeton University Department of Chemical and Biological Engineering in 2021-2023, the graph shows 32 visible PIs and 42 internal PI collaborations. The dominant subject mix is Engineering as the leading field (19% of slots across 13 PIs; 13 labels), Materials Chemistry as the leading subfield (13% of slots across 11 PIs; 11 labels), and Cellular Mechanics and Interactions as the leading topic (4% of slots across 4 PIs; 4 labels). That is a healthy pattern, with enough links to reveal several interpretable groups rather than one undifferentiated component. The top weighted PIs are Zhiyong Jason Ren (27.9 weighted works; CO2 Reduction Techniques and Catalysts, Microbial Fuel Cells and Bioremediation); Christos T. Maravelias (27 weighted works; Process Optimization and Integration, Advanced Control Systems Optimization). The most visible ties are Kurt D. Ristroph and Robert K. Prud’homme (9 shared works, weight 5.8); Rodney D. Priestley and Craig B. Arnold (10 shared works, weight 5.5). The standout breakdown groups are group 1 with 9 PIs, 12 internal connections, weight 28.4, around Materials Chemistry, Electrical and Electronic Engineering, Renewable Energy, Sustainability and the Environment, led by Zhiyong Jason Ren, Rodney D. Priestley, Yueh‐Lin Loo; group 2 with 8 PIs, 7 internal connections, weight 9.1, around Molecular Biology, Cell Biology, Atomic and Molecular Physics, and Optics, led by Celeste M. Nelson, Athanassios Z. Panagiotopoulos, Stanislav Y. Shvartsman.
