Talk Title: Molecular Engineering of Biointerfaces and Intrinsically Disordered ProteinsâÂÂ
Abstract: I will describe two disparate projects in this talk that illustrate the diversity of ongoing workin my laboratory. In the first half, I will describe a point-of-care diagnostic—the D4 assay—that we have developed, in which all reagents are printed and stored on a “non-fouling”—protein and cell resistant—polymer brush. The D4 assay has no moving parts, does notrequire a cold-chain, and works from a single drop of blood with minimal user intervention,and measures the concentration of multiple analytes with a sub-picomolar limit of detection.In the second half, I will introduce synthetic intrinsically disordered proteins (SynIDPs) thatare genetically encoded polymers of short peptide repeats that exhibit upper criticalsolution temperature (UCST) or lower critical solution temperature (LCST) phase behavior,like many naturally occurring IDPs. Because of their simplicity, the phase behavior ofSynIDPs can be rationally tuned at the molecular level by control of their sequence,composition, and chain length. I will describe how SynIDPs can be used to develop simplebut powerful tools for biotechnology and for the design of synthetic biomolecularcondensates in live cells to control diverse cellular functions

Presentation Title: Towards Publicly Verifiable Cryptography: Obfuscation, Fully Homomorphic Encryption, and Proof Carrying State.
Date and Time: April 17th 12:00pm to 1:30pm
Location: Ginsburg 503C
Committee members: David Kempe, Greta Panova (math department), Vatsal Sharan, Shanghua Teng, Jiapeng Zhang
Abstract: We explore public verifiability in cryptography. This proposal highlights two main results and one ongoing research direction:
Through a quantum lens, we introduce Quantum Obfuscation for approximate Unitary Quantum Functionality. By using advanced quantum techniques, our construction supports approximate unitary quantum functionalities with quantum inputs and outputs, significantly extending beyond existing limitations by Bartusek et al (STOC 2023, STOC 2024). Utilizing Quantum Teleportation combined with Projective Linear Measurement (PLM) quantum programs, we overcome critical obstacles from previous works and open potential applications in quantum copy-protection, quantum functional encryption, and secure quantum software distribution.
From a classical cryptographic perspective, we develop a Publicly Verifiable Fully Homomorphic Encryption (pvFHE) scheme, building upon the FHEW framework by Ducas and Micciancio (Eurocrypt 15). Integrating the GINX homomorphic accumulator, our scheme improves efficiency during bootstrapping and verification. Moreover, we introduce a generalized Rank-1 Constraint System (Ring R1CS) and construct a succinct non-interactive argument (SNARG). This approach provides efficient verifiability and strong security guarantees, including enhanced client data privacy, adhering to the recently introduced privacy framework by Cini et al. (Crypto 24).
Finally, our ongoing project, Proof-Carrying Quantum States, further extends these concepts to achieve verifiable quantum computations, bridging classical and quantum cryptographic techniques to ensure computation integrity and privacy. Together, these contributions advance both theoretical foundations and practical applications of publicly verifiable cryptographic protocols.Location: Ginsburg Hall (GCS) - 503C
