As a researcher at the National Cancer Institute, part of the National Institutes of Health, I work broadly in the areas of genomics and bioinformatics of high-throughput data analysis. In addition to data analysis and biologically-driven projects, I have a strong interest in developing software and tools for analysing and interpreting genomic data and help to lead the Bioconductor project.
