01. About

I am Jacky Jiang, a B.S. student in Computer Science and Statistics at the University of Illinois Urbana-Champaign (’27). I am also an operator, optimist, and communicator with active listening and strategic thinking. Pace, grit, and empathy are the primary tools I use to achieve high-level results.

In industry, I’ve completed five internships across five different industries — finance, entertainment, logistics, edtech, and agriculture. Across all five, what I enjoy most and do best is helping businesses turn raw data into better decisions. On my own time, I run an agentic trading system and an end-to-end retention analysis covering 50K users and 1.5M streaming events.

In research, I co-authored Steer2Adapt (advised by Prof. Jiaxuan You, UIUC) — inference-time LLM adaptation via composed steering vectors, accepted at the ICLR 2026 Re-Align Workshop and under review at NeurIPS 2026. I also build the real-time diarization and live-summarization pipeline for ScribeAR, an open-source captioning platform for deaf and hard-of-hearing students.

Looking forward, I’m excited to further deepen my AI and data science toolkit expertise, as well as GPU programming with CUDA. Let’s connect to explore collaborations in AI-driven analytics, machine learning, or quantitative trading!

Off the clock: tennis, baseball, and photography.
