Cristian C. Lalescu studied physics at the University of Craiova (UCv), from which he received his diploma in 2006. He then spent a year at the Free University of Brussels (ULB), through the SOCRATES/ERASMUS exchange program. In 2007 he started a joint doctorate program, under the supervision of Prof. Daniele Carati from ULB and Prof. Bucur D. Grecu from UCv, working mostly in Brussels.
After having defended his thesis in 2011, he joined the group of Prof. Gregory L. Eyink in the Department of Applied Mathematics and Statistics of the Johns Hopkins University in Baltimore, USA, as a postdoctoral fellow. In the summer of 2015 he moved to the MPIDS to join the Wilczek group. He is primarily interested in dynamical system theory, turbulence and the related mathematics and computer science.
