New York City is a diverse center of internationalism, and its scientific resources mirror that diversity, say researchers. The city's teaching institutions draw a high percentage of top-notch individuals from around the world. Mount Sinai Medical Center, for example, currently hosts postdoctoral fellows from 45 nations, and PhD and MD/PhD students from 25 countries in Europe, Africa and Asia, including places such as Albania, Lebanon, Armenia, Ghana, Thailand, and Taiwan, according to Mount Sinai's associate director of external affairs Debra Kaplan.
