The French Académie des Sciences awarded one of its prizes for 2017 (Le Prix Leconte) to our colleague Nikolay Tzvetkov.

The Leconte Prix (in French: Prix Leconte) was founded in 1886 by the French Academy of Sciences to honor breakthroughs in mathematics, physics, chemistry, natural sciences or medicine. In recent years, the award has been awarded to specific categories of mathematics, physics and biology. Laureates of the Award can be scientists and mathematicians of all nationalities.

Nikolay Tzvetkov obtained his master's degree from Sofia University "St. Kliment Ohridski "in 1996, after which he became a PhD student at IMI-BAS under the supervision of Professor V. Georgiev. He defended his doctorate in 1999 at the University of Paris Sud, under the supervision of Jean-Claude Saut. Since 2009 Nikolay Tsvetkov is a professor of mathematics at the University of Cergi-Pontoise.

His research field is partial differential equations and more precisely the mathematical analysis of nonlinear waves with a particular interest in regularity issues, stability of solitary waves and the propagation of random waves.

In the summer of 2017 Prof. Tzvetkov was a plenary speaker at the International conference "Mathematics Days in Sofia", which was organized by IMI from 10 to 14 July.
