A genealogical training process, in which senior (advisor) scientists engage in cross-generational transfer of skills and knowledge to junior (advisee) scientists is one of the core organizational features of modern science. In this paper, we examine the consequences of the tension faced by all junior scientists: to build upon an advisor’s skills or to strike out on one’s own? We study the implications of advisor-advisee research overlap for emerging scientists’ performance by constructing a novel, bibliometric-record-based dataset on 15,271 U.S. biomedical scientists (advisees) who were trained in 7,924 PI advisors’ labs between 1972 and 2009. We assessed the junior scientists’ performance in the first ten years of their careers as independent PIs. Tests across multiple research-overlap measures and model specifications reveal a consistently positive relationship between maintaining a higher degree of proximity to advisor’s research areas and the junior scientist’s early-career funding and publication performance. However, evidence is weak regarding scientific impact and non-existent regarding research disruptiveness. We further test how advisor status moderates the research overlap-performance relationship using both a large-sample analysis comparing the performance of academic siblings, and a more stringent difference-in-difference analysis leveraging the exogenous timing of the status elevation events experienced by the advisor scientists when they receive major scientific awards. Both tests yield consistent evidence that the positive relationship between advisor-advisee research overlap and advisee’s early-career performance is reduced as the advisor’s status increases. Taken together, these findings provide a more complete understanding of how advisor-advisee relationships shape new scientists’ performance during early careers.
