I am broadly interested in the evolutionary ecology of ecological communities, and my background is in entomology and statistics. I use theoretical and empirical methods and try to combine the two as often as possible. My empirical research generally focuses on insect communities, but I have also worked on other systems through collaboration. Some of my research interests include:

How does coevolution alter the effects of climate change on ecological communities?

How do community structure and interactions alter ecosystem functions, such as natural pest control by insect predators?

How does climate change alter ecosystem functions provided by ecological communities?

How do land management regimes influence biodiversity conservation?

Evaluation of Beauveria bassiana for rust thrips control in Australian Bananas

Indicative Funding
$48,591 over 2 years, in partnership with FADA Pty Ltd ($48,593)
We will evaluate the ability of a common fungus known to infect insects to control rust thrips, which are economically important pests of Australian bananas. We will conduct field and laboratory work and to evaluate its effectiveness and natural occurrence on farms. The aims are to conduct on-farm surveys of the fungus on ecoganic banana farms, and culture surveyed farm-collected strains in the laboratory and evaluate their effectiveness. If successful, this will provide an ecologically friendly method of pest control that will improve banana yields and reduce the need for pesticide sprays.

Australian Lions Foundation - Scientific and Medical Research on Marine Species Dangerous to Humans

Where are they? Using eDNA as a bio-indicator of Box Jellyfish abundance.

Indicative Funding
Environmental DNA (eDNA), relates to short snippets of genetic material, released into the environment by an organism, through natural process such as cell sloughing and excretion. Very recently, methods have evolved, allowing this DNA to be filtered out of the environment and used as bio-indicators for processes such as species abundance, and, distribution modeling. This project proposes to run a pilot study, testing efficacy of eDNA as a tool to detect and quantity the abundance of Carukia barnesi polyp. If successful, this information will be used, alongside existing physiological and distribution data, to locate these polyps in the field.

Wet Tropics Management Authority - Student Research Grant Scheme

Evaluating butterfly conservation status in the Wet Tropics bioregion of Queensland, Australia

Indicative Funding
The project aims to investigate general butterfly abundance and diversity in three land management practices (forested, agricultural with a focus on sugarcane cultivation, and urban areas) within the Wet Tropics, Queensland. This is being done over a 12-month period to capture seasonal trends. Butterflies are being sampled using fruit-baited traps, and are marked and released following identification. A species-specific survey is also being done on the Ulysses butterfly using visual encounter techniques. In addition to the ecological survey, sugarcane farmers and residents of urban areas sampled are being interviewed to gauge their level of awareness of butterflies in their surroundings.

Powerlink Queensland - Contract Research

Abrasive Blasting - Are There Any Environmental Concerns

Indicative Funding
$74,284 over 2 years
The re-surfacing and re-use of existing high voltage towers instead of removing and replacing with new structures has the potential to alter the way that power transmission infrastructure is used in the long term in Queensland. This project will look at using abrasive blasting in the high value and sensitive landscape of the rainforests of the Wet Tropics and will develop the science narrative around how the process interacts with the local environment.
