Welcome!

I'm currently a PhD Candidate in Statistics at the University of Chicago working under Prof. Mary Sara McPeek. My research focus is in statistical genetics. Read more about it below.

Research

My work is on developing re-sampling methods in the context of association mapping with binary traits in structured samples

  • Quasi-Likelihood Approach

    Generate replicates of the binary trait using a quasi-likelihood framework and use these to assess significance when performing association mapping.

  • Parametric Bootstrap

    Use a computationally efficient MCMC-based algorithm to fit a null model from which we generate trait replicates. We also construct a retrospective test for association mapping based on the fitted null model.

  • Retrospective approach

    Generate genotype replicates from a retrospective null model where the distribution of the genotypes is proposed conditioned on the phenotype and covariates (if any) and incorporates the structure present in the sample.
