Whos Where: Pierre Castinel is Head of Design at Tata

Indian automaker Tata has been front page news often in recent times, first because of the impressive one-lakh Nano, which changes the automotive industry playing field, and most recently because of its acquisition of Jaguar and Land Rover from Ford's Premiere Automotive Group for the tidy sum of $2.3 billion - less than half what Ford paid for both companies in 1989.  At the helm of Tata's design efforts is Pierre Castinel, Head of Design.

Castinel started as a modeler for Peugeot and worked there for three years.
