Introduction
My research focusses on the origins of the northern Australian flora, and the role of the Sunda-Sahul floristic exchange in shaping the region's flora. I'm interested in taking multi-lineage, multi-scale approaches using floristic, phylogeographic and phylogenetic data to tackle these questions.

The Miocene convergence of the Sunda shelf, Sahul shelf and Wallacea facilitated the exchange of previously
isolated floras across the Sunda–Sahul Convergence Zone (SSCZ). The SSCZ is a hotspot of biogeographical
research; however, phytogeographical patterns across the region remain poorly understood. We conducted
multivariate analysis on a compreh...
Aim
Exchange of plant lineages between Australia and Southeast Asia has had a substantial impact on the evolution of Australia's northern, tropical flora, with important ramifications for its conservation and biosecurity. Despite this, floristic exchange tracks between northern Australia and Southeast Asia remain poorly understood. To address this,...
Aglaia is the most widespread and species-rich genus in Meliaceae , comprising 124 species. Aglaia elaeagnoidea has presented a longstanding dilemma for taxonomists; it is highly morphologically and ecologically variable, and has a range extending across India, Southeast Asia, Australia and islands of the western Pacific Ocean. Previous work has ex...
Sapindales is an angiosperm order of high economic and ecological value comprising nine families, c. 479 genera, and c. 6570 species. However, family and subfamily relationships in Sapindales remain unclear, making reconstruction of the order’s spatio-temporal and morphological evolution difficult. In this study, we used Angiosperms353 target captu...
Faunal turnover in Indo-Australia across Wallace's Line is one of the most recognizable patterns in biogeography and has catalyzed debate about the role of evolutionary and geoclimatic history in biotic interchanges. Here, analysis of more than 20,000 vertebrate species with a model of geoclimate and biological diversification shows that broad prec...
Target capture has quickly become a preferred approach for plant systematic and evolutionary research, marking a step-change in the generation of data for phylogenetic inference. While this advancement has facilitated the resolution of many phylogenetic relationships, phylogenetic conflict continues to be reported, and often attributed to genome du...
Angiosperms are the cornerstone of most terrestrial ecosystems and human livelihoods1,2. A robust understanding of angiosperm evolution is required to explain their rise to ecological dominance. So far, the angiosperm tree of life has been determined primarily by means of analyses of the plastid genome3,4. Many studies have drawn on this foundation...
Aglaia fellii W.E.Cooper & Joyce (Meliaceae) is described from restricted areas of rainforest on Cape York Peninsula, Queensland, Australia. Given the unusual morphological features of the species, including solitary flowers and fruits, a molecular phylogenetic analysis was conducted to confirm its placement within Aglaia prior to formal descriptio...
Anacardiaceae is an ecologically and economically important plant family of about 200 species in 32 genera in the Neotropics.
The family is particularly diverse in leaf architecture and fruit morphology, making it a model family to study the
evolution of structural diversity as it correlates with lineage diversification. This fruit diversity is the...
Premise:
Hybrids contain divergent alleles that can confound phylogenetic analyses but can provide insights into reticulated evolution when identified and phased. We developed a workflow to detect hybrids in target capture data sets and phase reads into parental lineages using a similarity and phylogenetic framework.
Methods:
We used Angiosperms...
Premise:
Universal target enrichment kits maximize utility across wide evolutionary breadth while minimizing the number of baits required to create a cost-efficient kit. The Angiosperms353 kit has been successfully used to capture loci throughout the angiosperms, but the default target reference file includes sequence information from only 6-18 ta...

Premise of the study: Hybrids contain divergent alleles that can confound phylogenetic analyses but can provide insights into parental lineages when identified and phased. We developed HybPhaser to detect hybrids in target capture datasets and to phase reads according to haplotypes based on similarity and a phylogenetic framework.
Methods and Resul...
Universal target enrichment kits maximise utility across wide evolutionary breadth while minimising the number of baits required to create a cost-efficient kit. Locus assembly requires a target reference, but the taxonomic breadth of the kit means that target references files can be phylogenetically sparse. The Angiosperms353 kit has been successfu...
Background
The Sunda-Sahul Convergence Zone, defined here as the area comprising Australia, New Guinea, and Southeast Asia (Indonesia to Myanmar), straddles the Sunda and Sahul continental shelves and is one of the most biogeographically famous and important regions in the world. Floristically, it is thought to harbour a large amount of the world’s...
Unraveling the origins of Malesia's once vast, hyperdiverse rainforests is a perennial challenge. Major contributions to rainforest assembly came from floristic elements carried on the Indian Plate and montane elements from the Australian Plate (Sahul). The Sahul component is now understood to include substantial two-way exchanges with Sunda inclus...
Mycoheterotrophs, i.e. plants that acquire carbon from root-associated soil fungi, often have highly degraded plastomes, reflecting relaxed selective constraints on plastid genes following the loss of photosynthesis. Geosiris Baill. is the only mycoheterotrophic genus in Iridaceae and comprises two species in Madagascar and nearby islands, and a th...
The Tetratheca hirsuta Lindl. species complex from south-west Western Australia is one of the last unresolved complexes in this Australian endemic genus, and comprises the highly variable T. hirsuta, two rare, phrase-named taxa, and the closely allied T. hispidissima Steetz. An integrative approach, incorporating multivariate morphometric analysis...
