I do research on post-quantum cryptography. Specifically, I focus on applying post-quantum cryptography to the internet. Notable work I've done is investigating TLS without handshake signatures (KEMTLS). I have also done work on post quantum Signal handshake protocols. I'm active on PQC standardization and enjoy giving talks. In the IETF, I co-chair the PLANTS working group that is working on the standardization of Merkle Tree Certificates.
