He has managed a long term research budget, was leader of innovation management, led the reorganization of the R&D resource management of Renault, was head of a dealership and became the president of a distributor in a mature and an emerging market. He was the head of product and marketing for Toyota in Europe. He also served as senior advisor of Booz Allen and Hamilton (now Strategy &).

He established a new way of managing global products at Nissan and brand at Toyota combining the best elements of 2 worlds: global thinking using regional resources in a collaborative way and freedom in the implementation.

Among his key achievements are the award of “European Car of The Year” for Renault Clio1 that became the European best seller of its segment in Europe with 625,000 sales in 1992, the development of the product lineup at Nissan, which led to an improvement of global sales from 3.4 to 4.3 million vehicles -full effect in 2010-2011-, the initiation and development of the hybrid range of European products that resulted in an increase of sales volume of Toyota in Europe by 30% in 5 years from 500,000 to 650,000 units, together with share and profits, and the establishment of the Toyota global brand strategy and management after the recall crisis that saw the brand value (as calculated by Interbrand) grow again by 26 billion USD or 70% between 2010 and 2014.

As such GG has a unique and successful experience and can explain why he thinks there can be a different way of managing strategy, marketing and innovation in global firms.

He holds a Master of Science of French engineering school Ecole Polytechnique and an MBA of INSEAD, obtained with distinction.
