Didier Sornette is the author 500+ research papers and 7 books. To research his fields of interest Didier Sornette uses rigorous data-driven mathematical statistical analysis combined with nonlinear multi-variable dynamical models including positive and negative feedbacks. When “tired’’ by one subject, he finds refreshment and rejuvenation in shifting to another scientific
challenge. He is also adept of a healthy life, as explained in his “performance article’’ entitled “Optimization of brain and life performance: Striving for playing at the top for the long run. He practices actively the 7 principles outlined in this performance article, sleeps well, drink a lot of water, loves intensely, practice sports at a high level (winter ski, snowboarding, water monoski, wakeboard), eats a special diet, and promotes a psychology of “play’’ in all his activities and in his research team at ETH Zurich and internationally.
