Wei Vivian Li

PhD Student in Statistics

Wei (Vivian) is a Ph.D. candidate at UCLA Department of Statistics. She has a B.S. in Statistics from Huazhong University of Science and Technology. She is developing and improving statistical methods to uncover the hidden information in large-scale genomic data. Her research currently focuses on statistical modeling of both tissue-level and single-cell RNA sequencing data, and various applications in practical biological and biomedical questions. She is also interested in comparative analysis based on transcriptomic or epigenomic profiles from multiple tissues or cell types. She enjoys both the development of statistical methods and the application of these methods to real-world problems.

Research interests:

  1. Cost-sensitive machine learning methods
  2. Statistical modeling of bulk RNA-seq data
    • Annotation-based transcript reconstruction
