I work on applied cryptography, with a focus on public-key infrastructures and cryptocurrencies.
My interests lie at the intersection of theory and practice: I enjoy designing new cryptographic primitives and implementing them.
Most recently, I have worked on aggregatable subvector commitments from constant-sized polynomial commitments.
In the past, I have worked on scalable threshold cryptosytems, on faster proofs for polynomial commitments, on append-only authenticated data structures for public-key distribution, on scaling BFT algorithms, on leveraging the Bitcoin blockchain to prevent equivocation attacks in public-key directories, and on privacy-preserving file systems via ORAMs.
My publications, talks and service can be found on my CV here.
You can see me present some of my work on YouTube.
