Gender and the influence of research environment in topic selection of early-career faculty in STEM

We study the influence that research environments have in shaping careers of early-career faculty in terms of their research portfolio. We find that departments exert an attractive force over early-career newcomer faculty, who after their incorporation increase their within-department collaborations, and work on topics closer to those of incumbent faculty. However, these collaborations are not gender blind: Newcomers collaborate less than expected with female senior incumbents. The analysis of departments grouped by fraction of female incumbents reveals that female newcomers in departments with above the median fractions of female incumbents tend to select research topics farther from their department than female newcomers in the remaining departments -- a difference we do not observe for male newcomers. Our results suggest a relationship between the collaboration deficit with female incumbents and the selection of research topics of female early-faculty, thus highlighting the importance of studying research environments to fully understand gender differences in academia.

Differences in collaboration structures and impact among prominent researchers in Europe and North America

Scientists collaborate through intricate networks, which impact the quality and scope of their research. At the same time, funding and institutional arrangements, as well as scientific and political cultures, affect the structure of collaboration networks. Since such arrangements and cultures differ across regions in the world in systematic ways, we surmise that collaboration networks and impact should also differ systematically across regions. To test this, we compare the structure of collaboration networks among prominent researchers in North America and Europe. We find that prominent researchers in Europe establish denser collaboration networks, whereas those in North-America establish more decentralized networks. We also find that the impact of the publications of prominent researchers in North America is significantly higher than for those in Europe, both when they collaborate with other prominent researchers and when they do not. Although Europeans collaborate with other prominent researchers more often, which increases their impact, we also find that repeated collaboration among prominent researchers decreases the synergistic effect of collaborating.
