Research interests:

I'm interested in the interactions between humans and global environmental issues associated with climate change, agriculture and future food production. My research involves modeling analysis at the global scale.

For my master, I'm working on developing a global crop model to quantify the importance of management practices on crop yield in comparison with climate. More precisely, I'm looking at the effect of planting and harvest decisions, as well as irrigation and nitrogen fertilizer application on maize, wheat, and soybeans production at the global scale.

I presented some of my work on simulating planting and harvest decisions at the Annual Meeting of the American Geophysical Union (AGU), which took place in San Francisco in December 2008. I developed an algorithm to predict planting and harvest decisions according to temperature and soil moisture. (see maps below)

Originally from France, I have a background in Physics and Cosmology. While finishing my degree in Physics, I was really concerned about the whole climate change problem, and I started to feel the need to relate my research to people and current environmental problems. I had spent a year in Montreal as an exchange student, and I decided to go back there after completing my Master in Physics. Then, I had the great opportunity to meet Dr. Navin Ramankutty, and work as a research assistant in his lab before starting my Master in Geography under his supervision.
