I am a PhD candidate in Computer Science at the University of California, Santa Cruz, where I work on scalable privacy-preserving systems and applied cryptography. My research focuses on developing practical cryptographic protocols that enable secure computation over sensitive data while meeting the demanding efficiency guarantees of real-world applications.
I am particularly interested in the intersection of theory and practice — designing cryptographic systems that are not only provably secure but also efficient enough for real-world deployment. My recent work introduces scalable oblivious operators for secure databases in shared-memory environments.

My research lies at the intersection of cryptography, systems security, and privacy-preserving computation. I focus on developing practical cryptographic protocols that enable secure computation over sensitive data while maintaining strong privacy guarantees.
Current research areas include:
Oblivious Database operators for real-world applications
Oblivious RAM (ORAM) constructions and optimizations
Applied cryptography for distributed systems using Trusted Execution Environments.
I’m always interested in collaborating on challenging problems that bridge theory and practice in security and privacy.
Paper’s Abstract We introduce oblivious parallel operators designed for both non-foreign key and foreign key equi-joins. Obliviousness ensures nothing is revealed about the data …
