Ina Ganguli shares her research on the global mobility of scientists and its critical role in innovation. From Nobel Prize–winning breakthroughs to startup leadership, she shows how high-skilled immigration fuels the knowledge economy. Ganguli reflects on the historical brain drain from the former Soviet Union, the global impact of the COVID-19 vaccine developed by immigrant scientists, and how conflicts—like the war in Ukraine—can derail scientific ecosystems. She warns that barriers to migration and collaboration risk undermining the next generation of discovery and argues for policies that support scientific exchange, protect displaced researchers, and invest in international collaboration.
