Report summary

Duke University Department of Physics in 2015-2017 reads as a 31-PI network with 6 internal PI collaborations. The dominant subject mix is Physics and Astronomy as the leading field (44% of slots across 22 PIs; 22 labels), Atomic and Molecular Physics, and Optics as the leading subfield (21% of slots across 13 PIs; 13 labels), and Particle physics theoretical and experimental studies as the leading topic (10% of slots across 9 PIs; 9 labels). That is of concern for a 31-PI roster; the strongest pairings may be carrying much of the visible collaboration. The leading PI names are Ehsan Samei (14.4 weighted works; Radiation Dose and Imaging, Medical Imaging Techniques and Applications). The most visible ties are Venkitesh Ayyar and Shailesh Chandrasekharan (2 shared works, weight 2). The leading breakdown groups are group 1 with 3 PIs, 2 internal connections, weight 0.2, around Materials Chemistry, Atomic and Molecular Physics, and Optics, Spectroscopy, led by Weitao Yang, Gleb Finkelstein, Henry O. Everitt.
