Report summary

For Michigan State University Department of Physics and Astronomy in 2015-2026, the graph shows 97 visible PIs and 139 internal PI collaborations. The dominant subject mix is Physics and Astronomy as the leading field (52% of slots across 83 PIs; 83 labels), Nuclear and High Energy Physics as the leading subfield (24% of slots across 48 PIs; 48 labels), and Nuclear physics research studies as the leading topic (8% of slots across 24 PIs; 24 labels). That is a healthy pattern, with enough links to reveal several interpretable groups rather than one undifferentiated component. The top weighted PIs are Marcos Dantus (48.7 weighted works; Laser-Matter Interactions and Applications, Advanced Chemical Physics Studies); Angela K. Wilson (46.2 weighted works; Advanced Chemical Physics Studies, Per- and polyfluoroalkyl substances research). The most visible ties are A. Gade and D. Bazin (89 shared works, weight 14.3); G. Mark Voit and Megan Donahue (26 shared works, weight 12.1). The standout breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 18, around Materials Chemistry, Atomic and Molecular Physics, and Optics, Electrical and Electronic Engineering, led by Angela K. Wilson, Richard R. Lunt, Thomas W. Hamann; group 2 with 10 PIs, 17 internal connections, weight 75.8, around Nuclear and High Energy Physics, Radiation, Atomic and Molecular Physics, and Optics, led by A. Gade, B. A. Brown, D. Bazin.
