That looks relatively sparse, so claims about department-wide cohesion should be made carefully. The top weighted PIs are Jason A. Otkin (10.5 weighted works; Hydrology and Drought Analysis, Plant Ecology and Soil Science); Amy L. Cochran (9.5 weighted works; Digital Mental Health Interventions, Bipolar Disorder and Treatment). The most visible ties are Botong Wang and Laurenţiu Maxim (7 shared works, weight 5.2). The standout breakdown groups are group 1 with 2 PIs, 1 internal connections, weight 0.1, around Atmospheric Science, Global and Planetary Change, Statistical and Nonlinear Physics, led by Nan Chen, Samuel N. Stechmann.
