Research in the Bredy laboratory is aimed at elucidating how the genome is connected to the environment through epigenetic modifications, and how this relationship shapes brain and behaviour throughout life. The group is particularly interested in how epigenetic mechanisms, including DNA methylation, histone modifications. the activity of non-coding RNAs, and RNA modification regulate the formation and maintenance of associative fear-related memory.
Dr. Richard Gordon leads a multi-disciplinary, industry-partnered research program in Translational Neuroscience which integrates immunology, drug development, pharmacology, metabolomics and microbial metagenomics. His group aims to understand and therapeutically target key pathological mechanisms which drive the onset and progression of neurodegenerative disorders such as Parkinson’s disease (PD) and Amyotrophic Lateral Sclerosis (ALS). Their work combines target validation studies in human patients with mechanistic insights from disease models to develop and test novel therapeutic strategies that can be translated towards clinical trials.
Key research themes within this program include:
Understanding how chronic immune and inflammasome activation contribute to neurodegeneration in the CNS
The role of gut dysbiosis and gastrointestinal dysfunction in Parkinson’s disease pathophysiology
Therapeutic targeting of the gut-brain axis for neuroprotection
Drug discovery, development and repositioning for novel therapeutic targets
Discovery and validation of clinical biomarkers for PD and ALS
Clinical trials for disease-modifying therapeutic strategies
Dr Dhanisha Jhaveri has a joint appointment at Mater Research and the Queensland Brain Institute (QBI) and is a Mater Foundation Senior Research Fellow and a Group Leader. Dhanisha’s research group is investigating the fundamental mechanisms that drive the renewal of neurons in the adult brain, with the goal of harnessing this form of neural plasticity to relieve the emotional and cognitive burdens associated with chronic stress and depression.
Dhanisha received her PhD from the Tata Institute of Fundamental Research (TIFR), India, under the supervision of Professor Veronica Rodrigues, where she unravelled the molecular mechanisms that wire the olfactory axons in the fly (Drosophila) brain. In recognition of her doctoral work she was awarded the Indian National Science Academy medal for Young Scientist of the Year in 2003. Fascinated by the discovery that the production of new neurons continues in the adult brain, she then joined the laboratory of Professor Perry Bartlett at the Queensland Brain Institute as a Human Frontiers Science Program Postdoctoral Fellow. She has made major discoveries that have transformed our understanding of the regulation and roles of neural stem cells in the adult brain. Her work uncovered that a subclass clinical antidepressants directly activates neural stem cells in the hippocampus, a brain region implicated in regulating mood and cognitive functions. She also pioneered the development of a new cell sorting protocol to purify neural stem cells which revealed presence of distinct stem cell populations in this brain region.
Dr Odette Leiter is a postdoctoral research fellow in the research group of Dr Tara Walker, investigating systemic brain rejuvenation. She was awarded a PhD in Neuroscience in 2018 by the Technische Universität Dresden in Germany. Her research focus lies on the regulation of adult hippocampal neurogenesis by physical exercise, a process critically involved in learning and memory.
To support her research at the Queensland Brain Institute, Dr Odette Leiter has received two postdoctoral fellowships, a postdoctoral fellowship from the German Academic Exchange Service, followed by a Walter Benjamin Fellowship awarded by the German Research Foundation, allowing her to investigate the role of platelets in mediating neurogenesis-related learning and memory, and the capacity of platelet-released factors to restore cognitive function in ageing. More recently, Dr Leiter has been awarded a Discovery Early Career Researcher Award (DECRA) to investigate the precise mechanisms through which platelets interact with adult hippocampal neural stem cells following exercise.
Prof Nestor joined the Queensland Brain Institute in October/2017 and has a conjoint appointment as a cognitive neurologist at Mater Misericordiae Ltd (Mater Hospital).
His particular interests include understanding the earliest stages of Alzheimer's disease (i.e. before dementia is established); atypical forms of dementia with a particular focus on primary progressive aphasia and dementias related to Parkinson's and Lewy body diseases; and improving differential diagnosis between the major categories of neurodegenerative diseases.
He works on development of neuropsychological tests of cognition, both to accurately track change over time and improve diagnostic accuracy between the major diseases causing dementia. He also uses multi-modal imaging (magnetic resonance imaging [MRI] and positron emission tomography [PET]) to understand the sequence of events occurring in degenerative brain diseases (particularly Alzheimer's disease, frontotemporal dementia, Parkinson's disease, motor neuron disease [ALS], progressive supranuclear palsy [PSP] and corticobasal degeneration [CBD]) and identify novel biomarkers. A major focus of his is on developing novel approaches to MR imaging for single subject pathological diagnoses that can be exported into the everyday clinical setting; recent examples include diffusion tensor imaging to identify PSP and CBD (Sajjadi et al, 2013) and quantitative susceptibility mapping in Parkinson's disease (Acosta-Cabornero et al, 2013).
I graduated from The University of Tasmania, and received my PhD in Developmental Biology from The University of Queensland in 2003. My PhD, performed at the Institute for Molecular Bioscience with Prof. Melissa Little, centred on understanding the cellular and molecular mechanisms underlying embryonic kidney development. My first postdoc was performed with Prof. Christine Holt at The University of Cambridge, UK, where I studied the mechanisms by which axonal growth cones navigate to their targets in the brain, using the frog Xenopus laevis as a model system. In my second postdoctoral position, with Prof. Linda Richards at the Queensland Brain Institute at The University of Queensland, my work focussed on understanding the molecular mechanisms of neural progenitor cell specification in the developing cerebral cortex. In late 2010, I took up a joint position with the Queensland Brain Institute and The School of Biomedical Sciences (SBMS) to continue my research into the mechanisms underlying neural stem cell differentiation. I have held numerous fellowships during my career, including an NHMRC Howard Florey Fellowship, an NHMRC CDF and an ARC Future Fellowship. I currently hold a continuing Teaching and Research position within SBMS, and am currently the Director for Higher Degree Research Training at SBMS.
I am an early career neuroscientist investigating the capacity for neural progenitor cell behaviour to shape neural circuit formation, maintenance and function during development and throughout adulthood. More specifically, the role of oligodendrocyte progenitors and myelin in brain circuit formation and maintenance. My research examines the brain under health and pathological conditions by performing manipulations relevant to autism spectrum disorder, multiple sclerosis and schizophrenia. While under the supervision of Prof Helen Cooper at the Queensland Brain Institute – University of Queensland - I studied how the WRC-Cyfip1-FMRP protein network impaired apical radial glial progenitor function and neural migration, leading to cortical malformation and Autism-like traits in mice. During my PhD at University of Tasmania and under the supervision of Prof Kaylene Young, I studied the effect of neuronal activity on cells of the oligodendrocyte lineage. I found that voltage-gated calcium channels are critical for oligodendrocyte progenitor cell survival and characterised the impact of kainite receptor dysfunction on neuropathology and behaviour in mice. Currently under the supervision of Dr Carlie Cullen I am using transgenic mice strategies to determine how aberrant myelination can contribute to onset of neuropsychiatric and neurodegenerative disorders. I am also using mouse models of demyelination to investigate the effect of infectious diseases such as COVID19 and influenza on oligodendrocyte lineage cell function and the impact for myelin repair and multiple sclerosis disease progression. I have a long-standing interest in neuroscience research, that extends from understanding how brain function is regulated during development and in healthy ageing, and the dysregulated signalling pathways that enable neurodevelopmental and neurodegenerative disorders.
