We work at the intersection of genomics and neuroscience, utilising a number of 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 two main areas of investigation.
1. Risk genes for neuropsychiatric disorders
- Many regions in our DNA are known to confer risk to disease, including neuropsychiatric disorders such as schizophrenia and bipolar disorder, but the genes responsible and how they confer risk are often unknown. We are interested in identifying 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. Novel applications of Nanopore sequencing
- A second research area is to develop and utilise novel sequencing methods. We have worked in the past to help develop targeted RNA sequencing to allow 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 for this technology.
In addition, we have interests in multiple aspects of RNA biology including noncoding RNAs and RNA post-transcriptional regulation.
