About Me

Pronunciation: [ˈmilɑn loʷpuˈɦaʔa ˈzʋakəmbɛrχ]

I am an assistant professor at the FMT group, working on the CAESAR project under Mariëlle Stoelinga. My research focuses on mathematical properties of privacy, security and safety metrics and their applications. In particular I have studied differential privacy and its applications in data aggregation, machine learning, and distributed computing. My current research is on metrics for attack trees.


In the past I have also done research on comparative Indo-European linguistics, especially Albanian, and arithmetic algebraic geometry. My PhD thesis was on moduli spaces of abelian varieties.
