At the begin, I studied the impact of gaseous emissions from soils on the physics and chemistry of the troposphere. I have acquired a strong experience on various scientific issues. More, I led and participated in the implementation of many scripts / statistical programs for processing different types of data (meteorology, geochemistry, microbiology, plant biology, physics, ...). About my hobbies, I design a robot, artificial intelligences "user friendly" and I created a simple software of cryptography.
