The first genome-wide algorithm to detect STR expansions.
During my PhD I developed STRetch, the first algorithm able to detect STR expansions at all annotated STR loci across the genome from short read sequencing data. I demonstrated the ability of this method to detect pathogenic STR expansions and begin to characterize STR variation across the genome. STRetch was instrumental in the discovery of the Baratela-Scott Syndrome XYLT1 STR expansion and has been used to diagnose numerous patients with STR diseases.
Calling novel and reference STR expansions across the genome at scale.
Building on my PhD research, as a Postdoc in Aaron Quinlan’s lab at the University of Utah and in collaboration with Brent Pedersen, I developed STRling (https://github.com/quinlan-lab/STRling), a method to detect STR expansions from short-read sequencing data. It is capable of detecting novel STR expansions: expansions where there is no STR in the reference genome at that position (or a different repeat unit from what is in the reference). It can also detect STR expansions that are annotated in the reference genome in a way that is computationally efficient and can scale to thousands of genomes in the cloud. STRling uses k-mer counting to recover mis-mapped STR reads. It then uses soft-clipped reads to precisely discover the position of the STR expansion in the reference genome. I have already run STRling on almost ten thousand human genomes, including 1000 Genomes, CEPH three-generation families, individuals from TOPMed, and hundreds of families with a rare disease but no genetic diagnosis.
Clinical exome and whole genome sequencing pipelines and variant prioritization.
I worked as a Bioinformatician for the Melbourne Genomic Health Alliance, a project to trial clinical exome sequencing as the standard of care. As part of this project, I contributed to the development of Cpipe, a pipeline for variant detection and genetic diagnosis. I was involved in the initial scoping and testing of this pipeline as well as performing analysis for the first few patient cohorts. Cpipe has since been adopted by a number of diagnostic laboratories and has been instrumental in diagnosing many patients. I had the opportunity to lead and contribute to several other clinical genomics projects during my PhD at the Murdoch Children’s Research Institute. In particular, I deployed and assessed a clinically-driven strategy to prioritize variants from clinical exome sequencing at the Royal Children’s Hospital. We showed that a custom gene list approach outperformed state-of-the-art variant prioritization strategies. With Brent Pedersen and the Quinlan Lab, I then generalized my experience with exome analysis to help develop recommended filtering strategies that can be applied to the majority of exome and whole genome cohorts. We provide a fast filtering tool, slivar, to apply these filters and a language to define additional pedigree-aware custom strategies.
Developed a widely-used method to detect antibiotic resistance genes in microbial sequencing data.
I was a key developer of the bioinformatic tool, SRST2 (https://github.com/katholt/srst2), working with Dr Kathryn Holt at the University of Melbourne. The method quickly and accurately detects microbial antibiotic resistance genes and other critical genetic sequences from high throughput sequencing data of bacterial isolates. It uses competitive alignment and scoring of short reads to a database of known antibiotic resistance genes and other genes that impact microbial pathogenicity. SRST2 is a significant advance over previous slower and less accurate assembly-based methods. SRST2 has since been adopted by public health laboratories across the world and has been cited over 800 times.
Characterized a humanized mouse model of Methylmalonic Aciduria.
As a lab technician in the Cell and Gene Therapy laboratory at the Murdoch Children’s Research Institute, lead by Dr Heidi Peters, I contributed to the characterization of a humanized mouse model of Methylmalonic Aciduria (MMA). MMA is an autosomal recessive disorder that causes severe metabolic acidosis and can result in infant fatality. I developed techniques for metabolite measurement in urine, plasma, and tissue, and characterized genetic lesions using PCR, Sanger sequencing, real-time quantitative PCR, agarose and polyacrylamide gel electrophoresis, bacterial cloning, and DNA isolation. This mouse model was used to develop and test potential MMA therapeutics.
In addition to my scientific contributions, I also strongly believe in contributing to the broader research community through teaching and community outreach. To this end I have volunteered to teach Software and Data Carpentry workshops across Australia, in the US, and in India, to upskill researchers in computational approaches. I have developed lesson materials for general data analysis as well as genomics and RNAseq. I have substantial experience in teaching bioinformatics and genetics at both the undergraduate and graduate levels. I co-authored the book “Elegant SciPy”, which teaches cross-disciplinary approaches to scientific programming. I have also written editorials for PLoS Computational Biology and volunteered on a number of scientific and conference committees (detailed below).
I believe that diversity is key to a successful research community. To that end, I committed to mentoring and supporting women, members of the LGBQT+ community, neurodivergent people, people of colour, and parents. I further commit to making our research spaces, such as conferences, more inclusive of the full spectrum of human diversity.
