About Me

I am pursuing a bachelor’s degree at The Hong Kong University of Science and Technology (HKUST), double majoring in Mathematics and Computer Science. I am currently working on Conformal Prediction and Selective Inference, where I am fortunate to be advised by Dr. Ying Jin at the Harvard Data Science Initiative. Dr. Jin is also an incoming Assistant Professor at the Wharton School of the University of Pennsylvania. Before that, I was a research assistant working on Cognitive Science and Intention Understanding at the KnowComp Group at HKUST, where I have been fortunate to be advised by Prof. Yangqiu Song. I visited the School of Mathematics at ETH Zurich as a university exchange student during the spring of 2025.
