Deepak develops the crop statistics database for GLI and then uses them to answer questions on global food and agriculture. To date he has investigated the status of the Green Revolution, global crop production scenarios based on current trends, and the agriculture-climate relationship. He has also published peer reviewed articles in other related earth system disciplines. Deepak is a permanent resident of the United States.
