I recently became a Research Scientist at Agriculture Victoria, working on bioinformatics, computational biology, and genomics. Some of my projects include improving metabarcoding approaches to study the spread of insect and fungal agricultural pests, and functional genomics in grape phylloxera.
Previously, I worked as a Post-Doctoral Fellow in Genetics (2020–2022) in the Mycology Lab (School of BioSciences, The University of Melbourne) with Alexander Idnurm and Angela Van de Wouw, studying the fungal plant pathogen Leptosphaeria maculans, the cause of blackleg, a devastating agricultural disease that affects canola (Brassica napus) crops in Australia and many other countries.
I used genomic, molecular and population genetic methods to explore the evolution of fungicide resistance in L. maculans, as well as establish and coordinate a new international collection of fungal isolates to use as a panel of genetic variation for this species.
My PhD research (2016–2020) in the Robin Lab (School of BioSciences, The University of Melbourne) focused on a poorly characterised group of genes in insects called the ecdysteroid kinase-like (EcKL) gene family.
Using comparative phylogenomic methods and the powerful reverse genetics toolkit of Drosophila melanogaster, I found that EcKL genes are likely a novel detoxification family in insects and modulate susceptibility to natural toxins found in plants and fungi. Unsurprisingly, some EcKLs also encode enzymes that appear to modulate ecdysteroid hormone activity and may coordinate unknown aspects of insect endocrinology.
