🌈 Greetings! I am Yasi Zhang (She/They), currently a PhD student in the Department of Statistics and Data Science at UCLA. I’m fortunate to be co-advised by two of the best advisors in the world, Prof. Ying Nian Wu and Prof. Oscar Leong. Previously, I earned my bachelor’s degree in Data Science and Big Data Technology from Fudan University. In summer 2024, I conducted a research internship at Amazon AWS AI Labs. I will be joining Google Research for a student researcher internship in Spring 2025.
