About Me

I’m a Biostatistics Ph.D. candidate at New York University’s Grossman School of Medicine, working under the mentorship of Prof. Thaddeus Tarpey. My research involves developing statistical models that cater to high-dimensional complex data, such as functional and imaging data.

In the summer of 2022, I had the opportunity to work as a Data Scientist Intern at Google, where I applied my statistical skills to real-world problems. Prior to joining the Ph.D. program, I completed my master’s degree in Biostatistics and Data Science from Cornell University advised by Prof. Iván Díaz, and my bachelor’s degree in International Finance from Capital University of Economics and Business.

Outside of academia, I began my journey as a professional swimmer at the age of 5 and went on to achieve several regional and national championships. I’m also passionate about Chinese calligraphy, and my artwork has been exhibited in top galleries and museums including the National Art Museum of China (Beijing). In addition, I am also interested in oil painting, and aeromodelling.
