ABOUT

I lead the Computer Architecture and Security Laboratory (CASLAB) at Yale University, where I am fortunate to work with a great group of students. My research broadly focuses on computer security, with special interest in architectures and hardware for securing computer systems and cloud cyber-infrastructures. Beyond research, I enjoy teaching and I am a recipient of the 2021 Ackerman Award for Teaching and Mentoring.

RESEARCH

My recent, novel research findings include power side-channel vulnerabilities in quantum computer controllers and attacks on reset gates in quantum computers. My other exciting research findings include novel Secure TLBs and frameworks for security verification of processor caches and whole architectures; hardware accelerators for code-based and hash-based post-quantum cryptographic algorithms, as well as hardware accelerators for digital signature schemes currently being considered for standardization by NIST. I also research security attacks and defenses for nascent Cloud FPGA computing paradigm and novel side and covert channels in Cloud FPGAs; and DRAM-based Physically Uncloneable Functions.

My research is supported through current grants: NSF grant 2312754 (Quantum Databases); NSF grant 2245344 (Side Channel Detection and Repair); NSF grant 1901901 (Cloud FPGA Security); and NSF grant 1651945 (DRAM PUFs). In addition, my research benefits from grants and funding from SRC and TII. I am also thankful for industry donations from Xilinx and Intel (formerly Altera), and for donation of cloud computing credits from Amazon (AWS). I am further thankful for support of IBM Quantum and Quantinuum with their in-kind donation of compute access to their quantum computers.

INDUSTRY AND GOVERMENT COLLABORATIONS

I have a new (2023) collaboration with Quantinuum on security of ion-trap quantum computers. I have a new (2023) collaboration with SandboxAQ on hardware implementation of post-quantum cryptograhipc digital signature schemes. I also have ongoing (since 2020) collaboration and research grant with TII on hardware implementation of post-quantum cryptograhipc algorithms.

I am a member of ATARC (Advanced Technology Academic Research Center) Global Quantum Working Group. I am also part of the Classic McEliece team in NIST's PQC standardization process.

PROFESSIONAL AFFILIATIONS AND MEMBERSHIPS

I am affiliated with Yale's Applied Cryptography Laboratory and Yale's Computers Systems Laboratory. I have a courtesy appointment in Yale's Computer Science Department.

I am a Senior Member of the IEEE (2019), a Senior Member of the ACM (2022), a Member of the IACR, and an Associate Member of HiPEAC.
