Epigenetics & genomics of non-model organisms

We study how gene regulation is encoded in DNA methylation and chromatin, and we build the genomic resources and methods needed to ask those questions in species without well-developed reference genomes โ€” from insects and crustaceans to plants and extremophile microbes.

Epigenetics & DNA methylation

Mapping cytosine methylation and its regulatory roles โ€” from Dnmt1-driven gene silencing in pituitary tumours to non-CG methylation marking the pupa-to-adult transition in the moth Helicoverpa armigera.

Chromatin & histone modifications

Developing chromatin immunoprecipitation (ChIP) and profiling workflows for non-model organisms, including the first ChIP method for tephritid fruit flies and the histone modifications it revealed.

Genomics of non-model organisms

Building de novo genome and transcriptome resources across diverse species โ€” crustaceans, sea anemones and plants โ€” to enable functional and evolutionary discovery where reference genomes are sparse.

Applied & environmental biotechnology

Discovering and characterising thermostable enzymes from Great Artesian Basin microbes, including esterases that degrade plastics โ€” translating extreme-environment biology into biotechnology.

Selected work

A few representative papers led from the lab.

Insect DNA methylation

Non-CG methylation marks the pupa-to-adult transition in the moth Helicoverpa armigera, pointing to a developmental role for methylation outside the canonical CG context. Royle & Dudley, 2024 โ†’

Plastic-degrading enzymes

A moderately thermostable esterase from a Great Artesian Basin Bacillus velezensis degrades diisobutyl phthalate โ€” an enzyme prospected from an extreme environment for plastic breakdown. Mu et al., 2024 โ†’

ChIP for non-model species

A chromatin immunoprecipitation method adapted for tephritid fruit flies, providing evidence of histone modifications in an agriculturally important pest group. Nagalingam et al., 2018 โ†’
