She is a statistician with an interest in methodology for the analysis of genetic and genomic data. Her methodological work spans family studies looking for patterns of inheritance of disease-causing genes, case-control studies looking for associations between anonymous markers and disease status, gene expression studies examining differences between patient groups or tissues, and estimation of copy number variation in the genome. Some of the theoretical work developed by her students includes: a haplotype estimation algorithm using hidden Markov models, a flexible method for estimating disease-gene relationships in sparse data using Dirichlet process mixtures, and tree-based models for estimating the evidence for linkage in the presence of heterogeneity.<\/span><\/div>\n<div><span class=\"bodytext\">She led the statistical analysis team in a genome-wide association study of colorectal cancer, where a new locus was identified conferring increased risk. In the context of that study, the team proposed, and used, a novel stratified method for assessing false discovery rates, and developed a computationally-efficient method for empirically estimating large numbers of p-values for haplotype-disease associations.<\/span><\/div>\n<div>\u00a0<\/div>\n<div>\n<div><strong>Major Research Activities<\/strong><\/div>\n<div>\n<div>\n<div><span class=\"bodytext\">For many years,\u00a0Dr.\u00a0Greenwood\u00a0has been working on issues of data quality and measurement in genomic data, and how measures of quality can be developed and used to improve the detection of important signals in high-throughput genomic data. In particular, one focus of this research has been in data integration, where information from different experiments is combined to improve prediction performance or signal detection.\u00a0<\/span><\/p>\n<p><strong class=\"title\">Recent Publications<\/strong><\/p>\n<\/div>\n<div>\n<div><span class=\"bodytext\"><br \/>\nPingzhao Hu, Celia MT Greenwood, Joseph Beyene.\u00a0<\/span><em><span class=\"bodytext\">Using the ratio of means as the effect size measure in combining results of microarray experiments.<\/span><\/em><span class=\"bodytext\">\u00a0BMC Systems Biology 2009, 3:106. doi:10.1186\/1752-0509-3-106.<br \/>\n<\/span><span class=\"bodytext\"><br \/>\nBabak Shahbaba, Andrew J Gentles.
