Indian economist Arvind Subramanian, the Dennis Weatherstone Senior Fellow at the Peterson Institute for International Economics (PIIE) and Senior Fellow at the Center for Global Development (CGD), is likely to be named as India's chief economic adviser.
Here is more about Subramanian from the CGD site, and here is his biography from PIIE's site.
Although Subramanian may be leaving PIIE, the economic-oriented think tank recently announced it has hired Australian economist Justin Wolfers.
