We need a strong sense of national identity, not regional: Prof Mohanbir Sahwney

Mohanbir Sawhney is the director of the Center for Research in Technology and Innovation at Northwestern University, Illinois, and wants to use all his expertise to calculate the Global impact of the Indian Diaspora (or GDiP as he calls it), as the total value of the economy, philanthropic, intellectual and civic impact on the people, organizations, economies and the governments worldwide, which he says it needs to be measured and have an annual index to see in terms to define progress and success.
