About

I lead a diverse group of health practitioners and research scientists whose collective goal is to prevent vector-borne disease, especially dengue, in north Queensland.

We have received two NHMRC grants to develop green “Lure and Kill” dengue control programs for North Queensland.  I have been a principal investigator in the Eliminate Dengue program funded by the Bill and Melinda Gates Foundation since its inception in 2005. This innovative project utilises the bacterium Wolbachia to prevent the dengue vector Aedes aegypti from transmitting dengue viruses.  This partnership has already developed a molecular method to estimate the age of individual mosquitoes, and demonstrated that the parasite can effectively work in the laboratory and in semi-field cages. We are currently evaluating open field releases of Wolbachia-infected Ae. aegypti mosquitoes in Cairns. 

I am also involved in new projects studying the potential impact of global warming on dengue in Australia, new pesticides for the control of Ae. aegypti and the development of novel mosquito traps for the detection of pathogens in mosquitoes and other disease vectors.

I was employed as Director, Medical Entomology at the Tropical Regional Services (formerly Tropical Public Health Unit), the preventative health arm of Queensland Health in North Queensland, from 1994-2011.  There I have helped develop the world recognised Dengue Fever Management Plan for North Queensland.

Protecting north Queensland from Aedes albopictus, an exotic dengue vector, with Attractive Targeted Sugar Baits (ATSB)

Indicative Funding
$50,000 over 2 years
Summary
Aedes albopictus, a documented vector of dengue, Zika and chikungunya, is one of the fastest spreading invasive species worldwide, and was first detected in the Torres Strait in 2005. This pilot project will lay the foundation required to assess the feasibility of Attractive Targeted Sugar Baits (ATSB) to control Aedes albopictus. The overall objective is to determine the frequency that mosquitos? sugar feed, a parameter critical to the success of ATSBs. This pilot data will be leveraged for funding to trial the use of ATSBs to stop Ae. albopictus from reaching the mainland.

Australian Partnership (for) Preparedness Research on INfectiouS (disease) Emergencies (APPRISE)

Indicative Funding
$20,000 over 6 years (administered by University of Melbourne)
Summary
To ensure national and regional health security, emergency responses to infectious diseases must be highly effective, coordinated and based on the best available evidence. Research coordination, adaptable research protocols and efficient, secure data sharing are needed to develop a strong evidence base for preparedness, response and recovery from such events. This national consortium, with engagement of key animal health, community and international collaborators will focus on the major infectious diseases threats including influenza, coronaviruses, haemorrhagic viral diseases, arboviruses, syndromic presentations of novel pathogens and antimicrobial resistance. JCU involvement is through Prof. Ritchie and Peter Massey who are Ais on the project, offering advise. No funds are provided to JCU.

Beyond Thursday Island: Expanding the current Asian Tiger Mosquito (Aedes albopictus) control program across the Torres Strait

Indicative Funding
$25,000 over 2 years
Summary
Mosquitoes are uncontestably one of the deadliest animals in the world. Our project will investigate the Asian Tiger Mosquito (ATM), a major dengue vector in the TS. Outcomes of this project will directly benefit the people of FNQ. The overall purpose of this research is to investigate the ecology, distribution and dispersal of the ATM on islands in the TS. This project will gain information about the ecology, location and movement of the ATM on and between islands. This knowledge will form the basis for a potential surveillance tool for the ATM in the Torres Strait, which will reduce locally transmitted dengue and chikungunya viruses in FNQ.

Metofluthrin, a targeted intervention for high-risk persons during Zika, dengue, and emerging mosquito-borne disease outbreaks in far north Queensland

Indicative Funding
$24,000 over 1 year
Summary
In far north Queensland we have one of the world's most important mosquito vectors of dengue, Zika, and other viruses of public health significance. In this study, we look at interventions to protect high risk individuals from vector-borne disease in the event an outbreak scenario.

Application for Next Generation Sequencing of mosquito excreta to identify arboviruses, microorganisms and mosquito species

Indicative Funding
$35,000 over 1 year (administered by Menzies School of Health Research)
Summary
Traditional testing for arboviruses in mosquitoes requires a priori knowledge and choosing appropriate assays for their detection. Mosquitoes can potentially provide a lot of additional information, including other unexpected or unknown arboviruses, and their own genetic material. Moreover, mosquitoes in effect act as environmental samplers (?flying syringes?), taking blood from the humans and animals they feed upon. These blood samples could potentially be infected with other pathogens that are not necessarily mosquito-transmitted. Next generation sequencing is a rapidly advancing technology that allows us to obtain all this information from a sample without any prior knowledge of virus, host or vector. We are proposing to use next generation sequencing of mosquito excreta to identify pathogens in mosquitoes collected from locations where different vertebrate groups inhabit, including urban areas, bat colonies, domesticated animals, marsupials, reptiles and avian hosts.

Summary
North Queensland and the adjacent tropics are subject to incursions of exotic mosquitoes and the diseases they vector, especially dengue. I lead a diverse group of health researchers at JCU that develop strategies to prevent vector-borne disease in North Queensland that have global application. I am also employed as a consultant medical entomologies with Queensland Health, and thus am able to strategically apply my research on vector-borne diseases to end users.
