Research Interests

My research interests lie at the intersection of Systems and Algorithms. Specifically, in memory and resource efficient big-data computing, file systems, and security.

My current research focuses on building efficient approximate membership query data structures, specifically, counting filters and their applications. I am also working on finding efficient methods to represent large DNA sequencing and transcriptome datasets for De bruijn graph traversal and assembly process.

I am also interested in filesystem and write-optimized data structure research. I am currently a member of the team developing BetrFS, an in-kernel file system built using write-optimized indexes. I have also worked on developing an encrypted FUSE file system using Intel SGX as a summer project at Intel Labs.

I am being co-advised by Prof. Michael Bender and Prof. Rob Johnson at Stony Brook University, where I am currently pursuing my PhD in Computer Science.
