Mary Sara McPeek, Ph.D.


Research Description

My research interests are in statistical genetics and development of statistical methods. Software for most of my projects is available on my website. Specific current research interests include:

  • methods for haplotype analysis in dependent samples methods for genetic association analysis, including methods for binary, quantitative, longitudinal and X-linked traits
  • spectral analysis of population structure and other approaches to unknown population structure, particularly in the context of genetic association analysis
  • methods to detect association with copy number variation
  • methods for genetic analysis in isolated populations
  • relationship inference quasi-likelihood methods,
  • problems of incomplete data, and
  • applications of random matrix theory in statistical genetics
