Senior🎓
Top SchoolZheng Zheng is a Visiting Research Scientist and incoming Ph.D. student in Computer Science at UT Arlington with 11 years of technical experience and a strong foundation from a M.S. at Brandeis and a 4.0 B.S. in Geology. He designs and deploys end-to-end Retrieval-Augmented Generation systems, having built a pipeline that curated 8,000+ documents, applied Llama-index/Grobid parsing, and improved RAG answer correctness by over 25% through semantic splitting, MapReduce distillation, and bespoke evaluation metrics. His research focus spans LLMs, applied ML, computer vision and healthcare AI, blending full-stack engineering with model-centered systems work. An avid self-learner, he pairs practical production skills (web scraping, embeddings, clustering) with pedagogical experience as a CS teaching assistant, and — not obvious from his title — decompresses by rock climbing at Central Rock Gym.
