Report summary

For Pennsylvania State University Department of Mathematics and Computer Science Penn in 2015-2026, the graph shows 116 visible PIs and 41 internal PI collaborations. The dominant subject mix is Mathematics as the leading field (40% of slots across 84 PIs; 84 labels), Mathematical Physics as the leading subfield (13% of slots across 37 PIs; 37 labels), and Analytic Number Theory Research as the leading topic (4% of slots across 13 PIs; 13 labels). That looks relatively sparse, so claims about department-wide cohesion should be made carefully. The top weighted PIs are Wenwu Cao (65.7 weighted works; Ferroelectric and Piezoelectric Materials, Acoustic Wave Resonator Technologies). The most visible ties are Qingguo Hong and Jinchao Xu (9 shared works, weight 6.3). The standout breakdown groups are group 1 with 10 PIs, 9 internal connections, weight 22.7, around Computational Mechanics, Electrical and Electronic Engineering, Numerical Analysis, led by Wenrui Hao, Jinchao Xu, Xiantao Li.
