About Me

I am a third-year Ph.D. student in Computer Science at the University of Virginia, focusing on low-latency network protocols (L4S) and real-time media systems (WebRTC). My research investigates transport-layer congestion control and end-to-end performance in multi-site testbeds.

Previously, I worked on memory management for LLM inference workloads, edge-cloud optimization, and NLP for social media content moderation. I am interested in designing scalable, high-performance systems for real-world streaming and media applications.

Research Interests

• Low-Latency Network Protocols & Congestion Control (e.g., L4S)
• Real-Time Media Systems (WebRTC)
• Edge & Cloud Computing for Streaming Systems
• Memory Management and Caching for LLM Workloads
• Distributed Systems & Resource Optimization

Selected Projects

• PhD Research – Low-Latency Transport & WebRTC — Evaluating L4S congestion control in multi-site testbeds and analyzing end-to-end performance of WebRTC under varying network conditions.
• Lookahead Caching for Latency-Sensitive LLM Inference — Designed a caching policy improving memory reuse and latency in large-scale inference workloads.
• Laptop Components Classification for E-Waste Management — Built a labeled dataset and CNN pipeline for automated component classification.
• Neural Abstractive Text Summarization — Evaluated sequence-to-sequence models for generating high-quality abstractive summaries.
• Human-in-the-Loop Annotation for GitHub Comment Classification — Studied the impact of human feedback on improving LLM classification accuracy.
