        abstract = {Global mobility and migration of scientists is an important modern phenomenon with economic and
political implications. As scientists become ever more footloose it is important to identify general patterns
and regularities at a global scale. At the same time cities, and especially global cities, have become impor-
tant loci of economic and scientific activity. Limiting research to international migration, would disregard
the importance of local innovation systems. The analysis of the mobility and brain circulation patterns at
global scale remains challenging, due to difficulties in obtaining individual level mobility data. In this work
we propose a methodology to trace intercity and international mobility through bibliographic records. We
reconstruct the intercity and international mobility network of 3.7 Million Life Scientists moving between
9,745 cities. We present several features of the extracted network, offer evidence that the international
innovation system is marked by national borders and linguistic similarity and show that international mo-
bility largely contributes to the scientific output of national research systems. Moreover we find evidence to
suggest that global cities attract highly productive scientist early in their careers.},
