Overview
Background
Ji Hyun (Julia) completed her PhD in 2020 at the Dementia & Neuro Mental Health Research Unit at the University of Queensland Centre for Clinical Research and currently working as a postdoctoral research officer. Key areas of her current research focus are developing state-of-the-art neuroimaging analysis techniques related to emotional and cognitive dysfunctions in older persons and those with progressive neurodegenerative disease including Parkinson’s disease and dementia.
Her primary research themes include:
1. Identification of markers and mechanisms of mild cognitive impairment in Parkinson’s disease
2. Neuroimaging biomarker and repurposed therapeutic discovery to reduce risk of dementia in Parkinson’s disease
3. Understand the neurobiology of anxiety in ageing and its role in cognition.

The neurobiology of anxiety in ageing and its role in cognition
Anxiety is a common problem that can be experienced by people of all ages and it can negatively influence an individual’s overall well-being and quality of life. With a growing trend towards increased healthy life expectancy in an ageing population, there is the need to address anxiety disorders in older people. We aim to identify neuroimaging (brain scan) markers associated with anxiety in older people. In addition, we will examine the role of anxiety in cognitive functioning in older people. In your thesis project, you will learn a range of methods including conducting neuropsychological assessment, neurocognitive assessment and neuroimaging methods including functional magnetic resonance imaging (fMRI) data collection and data analysis.
