# Costanza Benassi

Hallo,

I am Costanza Benassi and I am a 3rd year PhD Student. Before my PhD, I earned a BSc in Physics and a 2-year MSc in Theoretical Physics at the University of Bologna, Italy. I am currently working under the supervision of Dr D Ueltschi.

My research area is Mathematical Physics, with a particular interest in lattice spin systems.

I usually work in B2.39, or you can email me at:

**TEACHING ACTIVITY**

I have been supervising a small group of 1st year students in 2014/2015 (Term 1), 2015/2016 (Terms 1 and 2) and 2016/2017 (Term 1). I am currently the TA for the MA4L2 Statistical Mechanics class (2016/2017, Term 2).
