Welcome!
I’m Davide, PhD student at Laboratoire d’Informatique de Grenoble in the POLARIS group, under the supervision of Panayotis Mertikopoulos and Bary Pradelski.
My research deals with geometric aspects of learning and evolution in games; contact me at davide dot legacci at univ-grenoble-alpes dot fr or head over to my blog to find out more.
