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.

My Ph.d. is about to end! I am **looking for a job!**

#### Practically this means that you can use or modify them as you please, according to the copyleft model. Let me know if you encountered problems using them, or if you have suggestions!

## 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. **

** I am a big fan of : **
