About

I'm a Computer Science student at Oregon State University. My internships have centered on AI and backend engineering: RAG pipelines and multi-agent workflows with LangChain and LangGraph, high-concurrency FastAPI services, an AI agent platform for automated telescope scheduling and surveys, and the development and testing of AI algorithms. In research, I've worked on parametric, interpretable models of human vibroacoustic sounds (paper published at IEEE EMBC 2026) and differential privacy for federated CNN training.
