Report summary

For Boston University Department of Biomedical Engineering in 2021-2023, the graph shows 60 visible PIs and 70 internal PI collaborations. The main research signal is Medicine as the leading field (27% of slots across 35 PIs; 35 labels), Biomedical Engineering as the leading subfield (13% of slots across 20 PIs; 20 labels), and Optical Imaging and Spectroscopy Techniques as the leading topic (4% of slots across 7 PIs; 7 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 Ji‐Xin Cheng (33 weighted works; Spectroscopy Techniques in Biomedical and Chemical Research, Photoacoustic and Ultrasonic Imaging); Mark W. Grinstaff (26.2 weighted works; biodegradable polymer synthesis and properties, Surgical Sutures and Adhesives). The clearest collaboration lines are David A. Boas and Xiaojun Cheng (15 shared works, weight 7.8). The strongest breakdown groups are group 1 with 10 PIs, 10 internal connections, weight 35.1, around Biomedical Engineering, Radiology, Nuclear Medicine and Imaging, Biophysics, led by Ji‐Xin Cheng, Lei Tian, David A. Boas.
