I am currently a Phd student at the University of Florence, under the supervision of Prof. Paolo Lisca.

I am interested in low dimensional topology, with a focus on knot theory and its many

connections with the topology of 3 and 4 dimensional manifolds.

My current work revolves around Khovanov and Knot Floer homologies,

especially Grid Homology in lens spaces.

## About me

** I am one of the organizers of the "Baby geometri" seminars at the University of Pisa. **

** I enjoy juggling any kind of objects, and thinking at all the math behind it. **
