Report summary

Yale University Department of Applied Physics in 2015-2017 reads as a 16-PI network with 15 internal PI collaborations. The research center of gravity is Physics and Astronomy as the leading field (34% of slots across 10 PIs; 10 labels), Atomic and Molecular Physics, and Optics as the leading subfield (20% of slots across 7 PIs; 7 labels), and Mechanical and Optical Resonators as the leading topic (9% of slots across 4 PIs; 4 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 Hui Cao (26 weighted works; Random lasers and scattering media, Optical Coherence Tomography Applications). The strongest pairings are Hui Cao and Michael A. Choma (14 shared works, weight 8.6). The strongest breakdown groups are group 1 with 10 PIs, 14 internal connections, weight 32.7, around Atomic and Molecular Physics, and Optics, Artificial Intelligence, Biomedical Engineering, led by Hui Cao, Hong X. Tang, Liang Jiang.
