Report summary

For Northwestern University Department of Mechanical Engineering in 2021-2023, the graph shows 33 visible PIs and 33 internal PI collaborations. The main research signal is Engineering as the leading field (45% of slots across 27 PIs; 27 labels), Biomedical Engineering as the leading subfield (13% of slots across 11 PIs; 11 labels), and Additive Manufacturing Materials and Processes 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 most prominent PIs by weighted works are John A. Rogers (57.2 weighted works; Advanced Sensor and Energy Harvesting Materials, Neuroscience and Neural Engineering). The clearest collaboration lines are John A. Rogers and Yonggang Huang (54 shared works, weight 26.6). The strongest breakdown groups are group 1 with 6 PIs, 5 internal connections, weight 12.1, around Biomedical Engineering, Civil and Structural Engineering, Polymers and Plastics, led by Wei Chen, Sinan Keten, Richard M. Lueptow; group 2 with 5 PIs, 6 internal connections, weight 14.9, around Mechanical Engineering, Automotive Engineering, Mechanics of Materials, led by Jian Cao, Wing Kam Liu, Gregory J. Wagner.
