About

I am an assistant professor at the Department of Biostatistics, University of Pittsburgh. I received my Ph.D. in Biostatistics from the University of Michigan, supervised by Dr. Peter X.K. Song. Before that, I received my B.A. in Mathematics and M.S. in Statistics from the University of Virginia.

I am especially interested in developing and applying statistical methods for biomedical data that inform health decisions made by individuals and health care providers. My current methodological research is driven by heterogeneous subpopulations detection, and mainly focuses on developing scalable and robust algorithms for statistical inference and data integration. I am currently working on collaborative projects in personalized medicine, health policy, environmental health, and metabolomics, developing useful tools for analyzing high-dimensional and complicated data (genomic, accelerometer, EHR, etc.). I am open to all kinds of collaboration opportunities.

Software

  • pgee: R implementation of penalized GEE with LASSO, SCAD and MCP [GitHub]
  • modac: method of divide-and-combine for penalized GLM
    Map-reduce functions in Python for fitting GLM when a dataset is large and stored on distributed Hadoop clusters. The method provides stable inference. [GitHub]
  • metafuse: fused lasso approach for data integration
    The package allows detection of heterogeneous effects across multiple independent datasets when analyzed jointly. It provides visualization of covariate-specific effect subgrouping via dendrograms, and enables variable selection. [CRAN] metafuse

Miscellaneous

  • Outside of work, I like to swim, run, and spend time with my family.
