My lab’s focus is in the development and application of sequencing technologies to gain a deeper understanding of biology and a more accurate set of clinical tools for human disease. We integrate biophysics, molecular biology and computational biology to create new tools for exploring the epigenome and genome. Leveraging these tools, we then explore interesting questions about fundamental biological concepts using model systems. We apply our newfound knowledge and toolset to clinical samples for diagnosis, surveillance and treatment of human disease. Recent projects range from diagnosis of infectious disease using nanopore sequencing, to developing new tools to characterize the genome and epigenome of cancer, to reading the transcriptome of the hummingbird.
