Report summary

The 2015-2017 picture for Columbia University Department of Mechanical Engineering is a 19-PI network with 9 internal PI collaborations. The main research signal is Engineering as the leading field (38% of slots across 14 PIs; 14 labels), Biomedical Engineering as the leading subfield (13% of slots across 6 PIs; 6 labels), and Elasticity and Material Modeling as the leading topic (6% of slots across 3 PIs; 3 labels). That is a thin collaboration pattern, useful for spotting individual pairs but less persuasive as a broad departmental network. The leading PI names are Gerard A. Ateshian (11.8 weighted works; Osteoarthritis Treatment and Mechanisms, Knee injuries and reconstruction techniques); Sunil K. Agrawal (11.6 weighted works; Robotic Mechanisms and Dynamics, Cerebral Palsy and Movement Disorders). The clearest collaboration lines are Y. Lawrence Yao and Dakai Bian (12 shared works, weight 9.3). The leading breakdown groups are group 1 with 7 PIs, 8 internal connections, weight 14.3, around Biomedical Engineering, Electrical and Electronic Engineering, Molecular Biology, led by James Hone, Qiao Lin, Cory R. Dean.
