Report summary

For University of Michigan–ann Arbor Department of Ophthalmology and Visual Sciences in 2015-2026, the graph shows 96 visible PIs and 440 internal PI collaborations. The main research signal is Medicine as the leading field (55% of slots across 82 PIs; 82 labels), Ophthalmology as the leading subfield (24% of slots across 58 PIs; 58 labels), and Retinal Diseases and Treatments as the leading topic (10% of slots across 27 PIs; 27 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 Yannis M. Paulus (67.4 weighted works; Photoacoustic and Ultrasonic Imaging, Retinal Diseases and Treatments); Joshua R. Ehrlich (60.1 weighted works; Ophthalmology and Visual Impairment Studies, Retinal Imaging and Analysis). The clearest collaboration lines are Maria A. Woodward and Paula Anne Newman-Casey (46 shared works, weight 24.9); Cagri G. Besirli and Thomas J. Wubben (34 shared works, weight 20.1). The strongest breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 116.3, around Ophthalmology, Radiology, Nuclear Medicine and Imaging, Epidemiology, led by Joshua R. Ehrlich, Paula Anne Newman-Casey, Joshua D. Stein; group 2 with 10 PIs, 11 internal connections, weight 81.6, around Ophthalmology, Molecular Biology, Radiology, Nuclear Medicine and Imaging, led by Cagri G. Besirli, David N. Zacks, Thomas J. Wubben.
