I consider myself the go to person in the lab when it comes to molecular biology work done in the lab. When I was an undergraduate, I worked in the Immunology lab of Kenneth Roux. During my work in the Roux lab, I did a lot of PCR and downstream cloning. Most of my work was focused on comparative genomics of the RAG1 gene in the immune system of lower vertebrates. Although I did not realize at it the time, I was doing comparative genomics! This was well before genome sequencing took off. For graduate school, I worked in the lab of William Marzluff studying the post transcriptional regulation of histone transcripts by SLBP (Stem Loop Binding Protein). My interest in histone regulation and histone modification is one of the reasons that drew me into looking at histone acetylation in song nuclei. We are using the regions where H3 histone is acetylated to identify regions in the genome where song nuclei are active. This will help us identify promoters that are specific or common to the song nuclei.
Before I joined the Jarvis lab I worked at Cogent Neuroscience. This startup biotech company was founded by faculty members from Department of Neurobiology at Duke University. During my time at Cogent Neuroscience I work on developing high throughput assays for discovering theuropeutics for Huntingtons disease. I also worked on identifying promoters that drive region specific gene expression in the brain.
I joined the Jarvis lab because I was interested in how behavior can alter gene expression in specific regions of the brain. For my work in the lab, I have focus on the song nuclei. For my first project in the lab I worked with Kazuhiro Wada on a songbird transcriptome sequencing project. I also worked with Patrick McConnell and Pankaj Agarwal on developing the songbirdtranscriptome.net database. I also supervised students who manually annotated the genes in the database. I later used our transcriptome along with two other published songbird transcriptomes to make an Agilent oligo array. This array was used by Osceola Whitney for his singing driven gene expression work. I also worked with Andreas Pfhenning when he identified human homologs to the genes we found in the songbird brain. He used this information to identify homologous regions in the songbird song nuclei and areas of the human brain by comparing the gene expression profiles. The human gene expression profiles were obtain from the Allan Brain Institute.
Currently, I am collecting tissue and blood samples from birds for genomic DNA isolation and downstream genome sequencing. We are attempting to sequence the genomes from all 30+ bird orders in an effort to better understand the phylogeny of birds. We are also using the genomes to study the genetic basis of vocal learning using comparative genomics. This project is being done in collaboration with BGI and the University of Copenhagen.
A fun side project that I have is genome sequencing and analysis of endangered animals. I am finishing up a genome sequencing project on the critically endangered Kakapo. I am working closely with the New Zealand Kakapo recovery team, life technologies, and the Canon Research Center on this project. I would like use the genome information to better find markers for genetic diversity. The aim is to facilitate breeding that will help the survival of the Kakapo. I also have several other similar collaborations with other conservation biologists to help species survival.
