Abstract The shift from basic to applied research is a key route by which science creates societal value, yet its career-level effects remain unclear. We analyze 30-year trajectories of 2,469 scientists using a novel Topic-Aware Level Score that quantifies each publication’s position on the basic–applied spectrum. 70% of researchers shift toward applied work; those in the top quintile of basic-to-applied shift are associated with higher citation impact compared to scientists with stable trajectories, whereas reverse shifts (applied-to-basic) show no comparable gains. Productivity follows an inverted-U pattern that peaks at intermediate shift magnitudes and declines for extreme transitions. Although demonstrated in nanocarbon field, an ideal testbed given its evolution from basic science to practical application, the framework is adaptable to other domains. Overall, we establish a large-scale, longitudinal baseline linking basic–applied career shifts to asymmetric outcomes, providing quantitative evidence relevant to policies that aim to support career transitions across research domains.
