Professor Elizabeth Aitken (Liz) obtained her BSc Hons in Agricultural Science (Crop Science) from Edinburgh University where she specialised in Plant Pathology. She then went on to undertake her PhD studies at Aberdeen University in conjunction with the UK Forestry Commission on a study of dieback on Scots pine trees. This was followed with postdoctoral studies at Birmingham University and the Sainsbury Lab, aiming to identify a rust resistance gene by transposon tagging. In 1993 she moved to Australia and joined UQ as an academic staff member.
Much of Liz’s research at UQ has focused on diseases of tropical crops in particular banana, ginger, cotton and sunflower. Research topics have included the genetics of plant-pathogen interactions, molecular aspects of pathogenicity and disease diagnostics. This research has been undertaken with strong collaborations with the Queensland Department of Primary Industries and with CSIRO. Research topics have included the genetics of plant-pathogen interactions, molecular aspects of pathogenicity and disease diagnostics. This work has assisted in the identification of disease incursions in particular in banana and of cryptic plant pathogen species of Pythium in ginger and Phomopsis in sunflower. One current research focus includes identification of resistance to Fusarium wilt in diploid banana lines for potential deployment against TR4 in commercial banana cultivars; this has received funding from BMGF in collaboration with the International Institute of Topical Agriculture in Africa as well as from Hort Innovation Australia. Other studies include analysis of putative pathogenicity genes including Six genes in Fusarium oxysporum affecting banana, strawberry and ginger and in collaboration with colleagues at CSIRO studies on Fusarium spp on wheat particularly with regard to influence of environmental factors related to climate change.
Since commencing at UQ in 1993, Liz has supervised numerous postgraduate and honours students and participated in undergraduate teaching at all levels in plant science and in particular in plant pathology and fungal biology. She has also taken on various roles and committee membership in postgraduate student mentoring, research integrity and biosafety.

In my PhD I analysed and modelled biophysical processes (light interception, transpiration and photosynthesis) and their relationships in apple and pear trees during the growing season and at different levels of plant water status. During this time I collaborated in the upgrade of a functional-structural peach model (L-PEACH). Later I focused my research on the effect of carbohydrates on grapevine and berry growth, as well as the effects of light, temperature and VPD on carbon assimilation and transpiration both at leaf and canopy level.
Currently, I am undertaking research on improving management practices in avocado, macadamia and mango. I am focused on studying architecture, vegetative vigour, crop load and light interception using functional-structural plant modelling to understand the interactions between management practices, environmental factors, plant carbon balance and growth.

Dr Botella's research interests are in genetic engineering, molecular biology and signal transduction in plants.
Dr. Jimmy Botella is Professor of Plant Biotechnology at the University of Queensland. He obtained a degree in Quantum Chemistry from the University of Madrid (Spain) and a PhD in Biochemistry from the University of Malaga (Spain). After postdoctoral positions at Michigan State University and Pennsylvania State University he joined the University of Queensland in 1995. At UQ he founded the Plant Genetic Engineering Laboratory (PGEL) specialising in the fields of tropical and subtropical agricultural biotechnology for almost 15 years. J. Botella has eleven international patents in the field of Plant Biotechnology and is a founding member of two biotechnology companies (Coridon Ltd. and Origo Biotech).
Dr Botella is a member of the Plant Molecular Biology and Biotechnology research group.
Some highlights of the Plant Genetic Engineering Laboratory’s research:
Production and field trial of the world’s first genetically modified pineapples with genetic constructs to control flowering time. These pineapples will allow farmer control over harvesting times.
Development of a new technology to confer protection against nematode infestation.
Discovery of a gene that can confer resistance to the devastating fungus Fusarium oxysporum in plants.
Development of a new technology to confer protection against pathogenic fungi in plants.
Research interests
Dr. Botella’s research has two major foci: basic cell biology and applied biotechnology. In cell biology he is interested in studying the function of the Heterotrimeric G proteins in plants. This family of proteins is extremely important in humans but their role in pant systems is still largely unknown. Dr. Botella’s research has strongly contributed to the current body of knowledge available in plants with critical contributions such as the discovery and characterization of the first plant gamma subunits and the establishment of these subunits as the critical element conferring function specificity to all plant G proteins. Dr. Botella’s team has also discovered the important role that these proteins play in defense against pathogens. New and unpublished data has now revealed that G proteins are important yield enhancing factors in crops such as rice. Another research interest resides in the communication between plants and insects. There is plenty of knowledge of how important smell, volatiles emitted by the plant, is for foraging insects in order to determine their host preferences. Nevertheless, most of the available studies have been performed using synthetic chemicals in artificial experimental settings. Dr. Botella’s team and collaborators have genetically engineered plants to produce different volatile mixes in the flowers in order to perform in vivo behavioral studies in insects.
Biotechnology research at the Plant Genetic Engineering Laboratory mostly arises from discoveries made in basic research. The PGEL focuses in tropical and subtropical crops. These crops have attracted little attention in terms of biotechnology but are essential sources of food and energy for a large part of the world’s population, especially in Asia and the Indian subcontinent. The PGEL has developed a number of platform technologies that can be applied to multiple crops in order to confer resistance to pathogens, modify plant architecture and control flowering time.
Current research projects include:
Plant heterotrimeric G proteins: New roles in defence, stomatal control and ABA perception.
Putting smells into context: using in vivo technologies to understand plant-insect odour communication.
Use of host-derived RNA interference technology to control plant pathogens (especially pathogenic fungi and nematodes).

As part of my PhD, I hypothesized that light, as an energy source and signal, plays a critical role in the processes of vegetative bud break, leaf fall and axis mortality in mango tree, and that incorporating these effects into the functional-structural plant model (FSPM) V-Mango, could lead to a significant improvement in model outputs. To evaluate this hypothesis, I studied the functional relationships between light quantity and quality in mature mango tree crowns. I also characterized and modelled the effects of architecture, light, and pruning on axis appearance and disappearance. Finally, all of these results were integrated into V-Mango after coupling it with a light interception model and the model outputs were successfully validated at the axis and whole tree scales.

Robyn's current projects involve developing propagation protocols for Australian native plants for food, ornamental purposes and land restoration.
My current research at UQ is as Professor in this School (teaching AGRC3040 Crop Physiology) and as an Affiliate Professor of QAAFI. Since 2020, with full-time appointment at UQ, my research portfolio has included multiple projects in applications of machine learning and artificial intelligence into the ag domain. This area is developing rapidly and across UQ, I am engaging with faculty in multiple schools (ITEE, Maths and Physics, Mining and Mech Engineering) as well as in the Research Computing Centre to develop new projects and training opportunities at the interface of field agriculture and these new digital analytics.
My career research has been around genetic and environment effects on physiology of field crops, particularly where drought dominates. Application of quantitative approaches (crop simulation and statistical methods) and phenotyping (aerial imaging, canopy monitoring) to integrate the understanding of interactions of genetics, growth and development and the bio-physical environment on crop yield. In recent years, this work has expanded more generally into various applications in digital agriculture from work on canopy temperature sensing for irrigation decisions (CSIRO Entrepreneurship Award 2022) through to applications of deep-learning to imagery to assist breeding programs.
Much of this research was undertaken with CSIRO since 1996. Building on an almost continuous collaboration with UQ over that time, including as an Adjunct Professor to QAAFI, Prof Chapman was jointly appointed (50%) as a Professor in Crop Physiology in the UQ School of Agriculture and Food Sciences from 2017 to 2020, and at 100% with UQ from Sep 2020. He has led numerous research projects that impact local and global public and private breeding programs in wheat, sorghum, sunflower and sugarcane; led a national research program on research in ‘Climate-Ready Cereals’ in the early 2010s; and was one of the first researchers to deploy UAV technologies to monitor plant breeding programs. Current projects include a US DoE project with Purdue University, and multiple projects with CSIRO, U Adelaide, La Trobe, INRA (France) and U Tokyo. With > 8500 citations, Prof Chapman is currently in the top 1% of authors cited in the ESI fields of Plant and Animal Sciences and in Agricultural Sciences.

I am an entomologist with a research interest focused on studying host-pathogen interactions and discovering insect-specific viruses. I have investigated gene expression and the role of small non-coding RNAs in various host-pathogen models, particularly in crucial agricultural pests and medically significant vectors like the Aedes aegypti, responsible for transmitting dengue and Zika viruses. My previous project, aimed at exploring the function of Oryctes rhinoceros nudivirus in the biological control of the coconut rhinoceros beetle in the Pacific Islands, has substantially enhanced our comprehension of this invasive pest within the framework of an offshore biosecurity strategy. By establishing industry partnerships and securing funding to improve the Australian sugar industry, one of Australia's largest agricultural sectors, I have been able to focus on entomopathogenic viruses that affect root-feeding pests in sugarcane.

My research focuses on the biological control and integrated management of insect pests. Understanding the ecological and biological relationships between insects and their natural enemies (pathogens, parasitoids and predators) and the interactions between these natural enemies is fundamental to effective biological control and is central to my research. Strategies which manipulate natural enemies to enhance their impact on pest populations are under development, examples include
Integration of biological stressors and fungal entomopathogens for improved control of insect pests
Reduced insecticide inputs combined with the provision of adult food sources to enhance endemic parasitoid performance
Utilizing inducible plant defences to manipulate pests and improve the effectiveness of natural enemies.
Externally funded research projects concentrate on the development of sustainable pest management strategies for insect pests in developing countries. In Indonesia the structure and function of the natural enemy complexes attacking the diamondback moth (Plutella xylostella) and the cabbage cluster caterpillar (Crocidolomia pavonana) are being determined. In Samoa the biology and ecology of the egg parasitoid Trichogramma chilonis is being investigated and the possibility of its release as a biological control agent of C. pavonana in Fiji, Tonga and Solomon Islands explored. Research in Fiji is focused on quantifying field resistance of the diamondback moth to commonly used insecticides. An insecticide resistance management strategy has been developed and will be implemented in collaboration with UN-FAO.

I am a plant pathologist specialising in the study of fungal pathogens of all manner of plants from agricultural and natural settings. My research career has spanned various areas of interest from horticultural and agricultural crop diseases, the development of disease forecasting systems, the study of soil mycorrhizal fungi, the use of beneficial microbes in promoting soil health and plant disease management and the scholarship of teaching and learning.
A key area of development has been the investigation of dieback disorders of invasive woody weeds in the Australian landscape. This has resulted in the development of a bioherbicide for the invasive weed Parkinsonia and the establishment of a start-up company - BioHerbicides Australia (BHA). BHA now produces this bioherbicide (which is a registered product) and has developed a range of synthetic herbicide products along with the delivery technology required for field implementation. My research team bioprospects for new control agents for a range of woody weeds (there are many) and also explores the use of synthetic herbicides. My research takes me to many interesting locations in outback Queensland, the Northern Territory, Western Australia and New South Wales. I am interested in many weed species including mimosa bush, chinee apple, celtis, prickly acacia, athel pine, mesquite, leucaena, rubber vine and various cacti.
I have been Deputy Head of School (Gatton) since 2013 where my main function has been to support the HoS as we develop this school through a process of growth and change with recruitment of new staff, development of new processes and teams and create a true sense of collegiality across both campus locations. We have taken Agriculture at UQ from an international ranking of #7 in 2016 to #3 in 2022. Apart from administrative tasks, my key role is to support and develop new staff to settle into their academic jobs, assist them with achieving milestones and probation and manage their development of KPIs and career development.
