Rate My Professor Adam Walker

Professor Adam Walker is an Honorary Professor at the Queensland Brain Institute, University of Queensland, where he leads the Neurodegeneration Pathobiology Laboratory. He obtained his BSc (Hons) in Biochemistry from the University of Tasmania and a PhD in Neuroscience from the Florey Institute of Neuroscience and Mental Health, University of Melbourne, focusing on the molecular mechanisms of motor neuron disease. Walker completed a postdoctoral fellowship from 2011 to 2015 with Professor Virginia Lee at the Center for Neurodegenerative Disease Research, University of Pennsylvania, during which he developed novel transgenic TDP-43 mouse models mimicking human motor neuron disease and frontotemporal dementia pathology. Previously an NHMRC CJ Martin Overseas Biomedical Research Fellow, he was awarded an NHMRC RD Wright Career Development Fellowship from 2018 to 2022. In 2018, as the Ross Maclean Senior Research Fellow, he established his laboratory at the Queensland Brain Institute. He is also a Bill Guest FightMND Research Fellow since 2022.

Walker's research utilizes biochemistry, imaging techniques, neuronal cell cultures, genetically modified mouse models, and human brain and spinal cord tissues to investigate TDP-43 proteinopathies in motor neuron disease (amyotrophic lateral sclerosis) and frontotemporal dementia. His group characterized the rNLS8 TDP-43 mouse model, demonstrating early cytoplasmic TDP-43 accumulation, activation of stress pathways, synaptic changes, microglial responses, glymphatic dysfunction, and progressive motor deficits. These models serve as platforms for dissecting disease mechanisms and testing preclinical therapeutics. His laboratory has received funding from the NHMRC, Australian National Foundation for Medical Research and Innovation, Dementia Australia, Motor Neuron Disease Research Institute of Australia, MonSTaR Foundation, and Cure for MND Foundation for projects on TDP-43 clearance, complement modulators, and protein homeostasis. Key publications include San Gil et al. (2024) 'A transient protein folding response targets aggregation in the early phase of TDP-43-mediated neurodegeneration' in Nature Communications; Luan et al. (2023) 'Early activation of cellular stress and death pathways caused by cytoplasmic TDP-43 in the rNLS8 mouse model of ALS and FTD' in Molecular Psychiatry; and Bademosi and Walker (2022) 'Cryptic inclusions UNCover losses driving neurodegeneration' in Trends in Genetics. Walker's contributions have provided critical tools and insights advancing therapeutic strategies in neurodegenerative diseases.
