🌈 Greetings! I am Yasi Zhang (She/They), currently a PhD student in the Department of Statistics and Data Science at UCLA. I’m super 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. I conducted an Applied Scientist internship at Amazon AWS AI Labs in Summer 2024 and a Student Researcher internship at Google Research in Spring&Summer 2025.
