We work at the intersection of genomics and neuroscience, utilising transcriptomic (RNA-Seq, Nanopore long-read sequencing, targeted RNA sequencing and single cell sequencing) and functional genomic approaches to investigate gene expression and function in the human brain and in neuropsychiatric disorders. Our laboratory has three main areas of investigation.
1. Risk genes for neuropsychiatric disorders
- Many genes in our DNA confer risk to disease, including neuropsychiatric disorders such as schizophrenia and bipolar disorder, but how they confer risk is generally unknown. We are interested in studying these genes, both protein coding and noncoding (i.e.: long noncoding RNAs) and how their expression can change to cause disease risk. We utilise both post-mortem human brain and neurons derived from induced pluripotent stem cells (iPSCs) to help answer these questions.
2. The role of gene isoforms in brain development
- Almost all human genes express multiple RNA products, (known as isoforms) through processes such as alternative splicing. Switches between isoforms play crucial roles in brain development, but we have previously lacked the technologies to systematically identify and functionally characterise the isoforms involved. Using long-read single-cell RNA sequencing approaches we helped develop, we are examining gene isoforms in stem-cell and organoid models of brain development and in-vivo.
3. Novel applications and tools for Nanopore sequencing
- We work to develop and utilise novel sequencing methods and informatic tools. Previously we co-developed targeted RNA sequencing to enable highly sensitive detection and quantification of genes of interest. More recently we have focused on utilising Nanopore sequencing, a technology that can sequence both DNA and native RNA. We are applying Nanopore sequencing to many research questions as well as developing novel applications and tools for this technology such as NanoCount, NanoSplicer and BLAZE.
In addition, we have interests in multiple aspects of RNA biology including noncoding RNAs and RNA post-transcriptional regulation.
