  • Lingjing (Serene) Jian

    Lingjing (Serene) Jian

    Statistics is a science as well as an art to Lingjing (Serene): she enjoys digging into the mathematical world for understanding the underlying theories and developing novel statistical methods; she also loves presenting and communicating statistics to the public. Serene grows up in Shanghai, China, and she received her bachelor degree in translation from Chinese University of Hong Kong, and her master degree in statistics at University of California, San Diego. Serene is especially interested in developing new statistical and mathematical tools for analyzing high dimensional medical data to bring more insights into the scientific understanding of human and environmental health. In her free time, Serene likes cooking, exploring different cuisines and inviting friends for tasting.
