Noah Golowich: On the Power of Multiple Anonymous Messages Wednesday, December 18, 2019  2:00pm to 3:00pm Abstract: 

Muthu Venkitasubramaniam: A RoundCollapse Theorem for ComputationallySound Protocols; or, TFNP is HardonAverage in Pessiland Friday, December 13, 2019  10:30am to 12:00pm Abstract: Consider the following two fundamental open problems in complexity theory: 

Dhiraj Holden: NoSignaling Proofs with sqrt(log n) Provers is in PSPACE Friday, December 6, 2019  10:30am to 12:00pm Abstract: Nosignaling proofs, motivated by quantum computation, have found applications in cryptography and hardness of approximation. An important open problem is characterizing the power of nosignaling proofs. 

Ashutosh Kumar: Securing Secret Sharing Against Leakage and Tampering Friday, November 22, 2019  10:30am to 12:00pm ABSTRACT: Secret sharing is one of the most classical and widely used cryptographic primitives. 

Daniel Wichs: Extracting Randomness from ExractorDependent Sources Friday, November 15, 2019  10:30am to 12:00pm Abstract: We revisit the wellstudied problem of extracting nearly uniform randomness from an arbitrary source of sufficient minentropy.

Adrienne Mannov: A Call for CryptoAnthropology Friday, October 11, 2019  4:00pm to 5:00pm Abstract: As a social anthropologist, cryptography is interesting because what counts as secure, what constitutes trust, and how sensitive information is perceived are not only cryptographic questions but deeply social ones.
