| contents | Scientific mobility shapes individual research careers and national innovation by enabling knowledge exchange, fostering collaborations, and providing access to leading research environments. Studying international mobility patterns of researchers from developing countries offers insights into strengthening domestic scientific ecosystems and addressing talent migration. We analyze the international mobility of India-affiliated researchers using longitudinal affiliation trajectories from the OpenAlex database, covering 157,471 researchers categorized as immobile, returnees, or settled abroad after moving to the US, EU, or other high-income countries. Our analysis shows that 28% experience at least one international move, yet over 73% never return, highlighting persistent brain drain. Internationally mobile researchers predominantly originate from premier Indian institutions. Matched pair analyses demonstrate that mobility yields lasting benefits: citation impact increases, publication rates align with immobile peers, and international collaboration rises-foreign co-author share grows from 52% to 83-87% at transition abroad and remains elevated among returnees (32-40 percentage points across disciplines). Returnees maintain global networks, bridging Indian science with global research. These patterns are consistent across major research disciplines, emphasizing that scientific mobility drives excellence and engagement while posing challenges for developing nations seeking to reintegrate talent. |
