My research projects use molecular genetic approaches to study centromere function and evolution; small RNA biogenesis; epigenetics, transcriptional control and chromatin modifiers; and whole genome and transcriptome sequencing in several model systems, including human, non-human primates, mouse, and marsupials. Using techniques such as in situ hybridization, microarray screening, cell assays, and next-generation sequencing (Illumina, 454 pyrosequencing, SOLiD 5500xl, Ion Torrent Proton), I am addressing the hypothesis that epigenetic modifiers (DNA methylation, histone modifications and small RNAs) mediate transcriptional controls and genome stability. I am lead PI on four de novo eukaryotic genome sequencing projects. I have produced next generation sequence for draft assemblies and my lab has written novel scripts for improving genome assemblies with data from multiple next generation sequencing platforms. We have been actively sequencing the unfinished portions of both the human and tammar wallaby (a marsupial model) genome using a combination of paired end sequencing, whole genome shotgun, BAC deep sequencing and FISH techniques. Moreover, I am involved in several different integrated genomics projects that include RNA-seq (small and whole transcriptome), ChIP-seq, RIP- seq, methyl-seq, and paired end sequencing targeting a Peromyscus disease model, a mouse model for Autism, human samples and patient-derived iPS cells, and several wallaby, primate, and marine species. I have worked with genomics techniques on several grants and research projects over the last 20 years focusing on genome stability and function. As Director of the Center for Genome Innovation within the Institute for Systems Genomics, I oversee the ABI SOLiD 5500xl, 454+ Genome Analyzer, Illumina NextSeq, Illumina Miseq and Ion Torrent Proton.
