About Jiaan Han

Hi there I’m Jiaan Han.I’m originally from Nanjing, China, where I graduated from Nanjing Foreign Language School before heading to the U.S. for college. Currently, I’m pursuing my MS in Financial Economics at Columbia Business School, after completing a triple major in Mathematics, Statistics, and Data Science at the University of Michigan.My journey has always been about finding the intersection of rigorous research and real-world markets. On the research side, I’ve explored stochastic asset dynamics and optimal control (HJB equations applied to nonprofit finance), built large-scale financial datasets, and worked on statistical learning methods like False Discovery Rate (FDR) control in LSTMs (recently submitted to a top AI conference). On the practical side, I’ve built and tested 200+ equity factors at Inno Asset Management, explored high-frequency market models in academic projects, and—like many curious quants—run my own stock portfolio where theory meets the unpredictability of live markets.I’m particularly fascinated by how AI and finance cross-pollinate: from using machine learning for robust risk control, to thinking about how LLMs might reshape trading research infrastructure. To me, quant research isn’t just about coding or equations—it’s about asking interesting questions and building tools that push both knowledge and practice forward.Beyond the research and coding marathons, I’m a big sports fan —I follow soccer games closely and enjoy how the dynamics of sports often resemble the unpredictability of markets.I’m always open to connecting with people across the spectrum—quant researchers, traders, data scientists, or just anyone curious about AI and investing. Fellow alumni and anyone who shares similar interests are welcome to reach me directly at j•••••@columbia.edu. And of course, feel free to connect here on LinkedIn—I’d love to chat.
