About

I will be starting as an assistant professor at USI (Università della Svizzera italiana) in January 2026. Until recently I was a PhD student at ETH Zurich in the applied cryptography group, advised by Kenny Paterson. I wrote my doctoral thesis on provable security for applied cryptography, focused on cloud storage security [1, 2, 3] and key derivation [4, 5, 6].

I am a co-founder and organizer of CAW, the Cryptographic Applications Workshop.

In the spring of 2025, I spent four months working at Apple as an intern in the Cryptographic Engineering team within Apple Security Engineering and Architecture (SEAR), applying my research to real-world cryptographic systems. Speaking of real world: my co-authors and I had three talks accepted at Real World Crypto 2025!

Before I joined ETH, I studied engineering mathematics at Lunds Tekniska Högskola (LTH) in Sweden. I also worked with Mihir Bellare during an exchange at UCSD. I wrote my master thesis on puncturable symmetric key encapsulation mechanisms, supervised by Felix Günther.

In my free time, I like climbing and hiking in the beautiful mountains of Switzerland, trying new foods and learning languages, among other things!
