About me

👋 Hi, I’m Ivy — I build things with AI, and I genuinely can’t stop. ⚡ What started as curiosity about how machines learn has turned into an obsession with making them do — reason, predict, collaborate, and surprise me. ✨

🎓 Right now I’m a Master’s student at Columbia University (Statistics & ML) 📊, a Research Assistant at Columbia CUIMC working with ICU data 🏥, and a Quant Systems Intern at RAYS in Hong Kong 📈 — all at once, because apparently I love a challenge. 💪 Before this, I studied CS at HKBU (Top 4%) 🏆 and spent a summer at Oxford diving deep into AI & ML. 🌍

🤖 AI is what gets me out of bed. I love how it keeps changing the rules — and I want to be one of the people changing them. 🔥 Whether it’s a multi-agent system that reasons 🧠, a model that understands language better than expected 💬, or a pipeline that just works at scale 🚀 — I’m here for all of it. 🌟
