I am currently a computer science PhD working with Prof. Pandey Prashant at Northeastern University DATA Lab. I focus on building high-efficiency systems for data at scale.
Projects
-
GPU Accelerated Approximate Nearest Neighbor Search
In this project, we built a library providing an updatable index for approximate nearest neighbor search on GPU. Our goal is to efficiently scale its construction and querying beyond GPU memory, handling vector search at billion scale.
-
Adaptive Streaming System
Mechanisms and policies for efficiently scaling streaming workloads at runtime.
