Zifeng Zhang

I am currently a Postdoctoral Associate in the Department of Biostatistics at the Yale School of Public Health, working with Professor Hongyu Zhao. I received my Ph.D. in Statistics from Colorado State University in 2025, where I was advised by Professor Wen Zhou and co-advised by Professor Haonan Wang. Prior to CSU, I received a B.A. in Insurance from the School of Finance and an M.A.S. in Applied Statistics from the School of Statistics and Data Science at Nankai University in 2016 and 2018, respectively.

Research interests:

  • Statistical inference under complex dependence and random design
  • High-dimensional statistics and structured regularization
  • Causal inference and high-dimensional mediation analysis
  • Statistical learning with external knowledge and semantic embeddings
  • Applications to biomedical and other complex data
