Understanding and modeling diverse scientific careers of researchers

作者:

Highlights:

• We define two metrics to measure the diversity of research career of a researcher.

• Researchers work on few areas in the entire career, with several areas at a time.

• Highly cited researchers typically follow “scatter-gather” policy in choosing areas.

• Low-cited researchers work on various areas at a time as well as in the entire career.

• Our stochastic model efficiently mimics the real dynamic of field selection process.
