Research Interests

I am interested in methods and applications of single cell gene expression assays. There is great hope, for good reason, that measuring expression profiles in single cells will aid in immunological and cancer research, and provide new insight in cellular biology (though it still only provides a cross-sectional sample of cells at various points in their lifespan and cell cycle.) However, the biochemical, computational and statistical challenges are sizable.

I am focusing on the combinations of all three. Through the use of unique molecular identifiers, it may be possible to better understand the biases and sources of variability current protocols introduce. I am writing R software packages to allow easier manipulation of single-cell data sets (which are sometimes almost as "tall" as they are "wide"). I am developing statistical methods that accommodate the bimodality of single cell data, which yield more sensitive and better calibrated tests.

Statistical questions I am currently interested in include:

  • Graphical modeling and gene-gene interaction networks
  • Clustering and distance measures for zero-inflated data
  • Gene-enrichment analysis
  • Regularizing vector generalized linear models through empirical Bayes' procedures
  • 2nd-order univariate phenomena, such as exceptional stability or heterogeneity of expression (and how this can be identified given differing levels of technical variability).
