Overview
I am a postdoctoral fellow in the Department of Biostatistics at Johns Hopkins. My advisor is Rafael Irizarry.
Research Interests
I am interested in computational biology, especially the analysis of high-throughput biological data. Biological areas of special interest are epigenetics (particular DNA methylation), gene expression, and biases in high-throughput technologies.
During my postdoc I have focused on developing methodology for analyzing next-generation sequencing data, with emphasis on bisulfite sequencing. I have applied this methodology to study DNA methylation in cancer. I have also worked on normalizing RNA sequence data.
During my Ph.D. I analyzed various custom microarrays, used for the study of alternative splicing as well as bacteria detection. I also worked on biases in RNA sequencing.
I am a contributor to the Bioconductor project, a co-author of the packages affxparser, cqn, Genominator, minfi, and Rgraphviz.
Biography
I received my Ph.D. in Biostatistics with a Designated Emphasis in Computational and Genomic Biology in 2009 from University of California, Berkeley under the supervision of Sandrine Dudoit. My thesis was titled "Some analyses of high-throughput expression data".
Prior to obtaining my Ph.D., I received my Master's degree in statistics from the University of Copenhagen in 2001. I subsequently worked approximately two years as a research assistant at the Department of Biostatistics, University of Copenhagen.
