# Jozefien D'haeseleer

### PhD-student Mathematics at UGent

I am doing a PhD at the University of Ghent, funded by the FWO Flanders and under the supervision of Prof. Dr. Leo Storme, Dr. Geertrui van de Voorde and Dr. Maarten De Boeck.

My research is situated in finite geometry and coding theory. I'm especially interested in Cameron-Liebler sets and intersection problems in projective and polar spaces.
