Jeg ser for tiden etter kandidater med god bakgrunn i diskret matematikk, statistikk, algoritmer o.l. til PhD eller Postdoc prosjekt.

I enjoy a wide interest in various topics related to cryptography and coding theory, mainly related to concrete applications. Current research topics include privacy preserving techniques (MPC/FHE, ZK-SNARKs/STARKs, DeFi, Blockchains...), symmetric key designs and analysis, algorithms and computation, post-quantum security...
