About me

I am actually a postdoc at Stony Brook University. Previously, I did my Ph.D under the supervision of Charles Favre. I am interested in the dynamics of rational maps on projective varieties of dimension larger or equal to three and in the theory of valuations on convex bodies.

Conference organization

03/21/20-03/22/20: AMS Special Session in Tufts, Algebraic geometry in dynamics.

I am a co-organizer of this AMS session together with Nicole Looper and Rohini Ramadas. The aim is to bring together students, postdocs and researcher working on algebraic dynamics. It will consist of 20 minute talks, as well as a discussion on open problems in the field.
