Yiqun Wang is a Ph.D. candidate in Financial Economics at UCL. I received an M.S. in Economics and Finance from CEMFI and a B.Econ. in Finance from Sun Yat-sen University. My research is in finance theory and studies the interplay between information economics and financial markets. A central theme is how technological change, especially FinTech platforms and AI systems, can make information more homogeneous across agents and reshape learning, trading, and market fragility. I also work on repeated games.
