Available Projects

1. PhD Scholarship available: Understanding the barriers and facilitators of delivering a technology-assisted telehealth psychotherapy intervention to people with dementia

As part of the study, we will undertake a process evaluation to assess treatment fidelity, dose and contextual factors that may influence effectiveness, to inform future implementation in community and memory clinic settings. The PhD project will focus on developing the future implementation framework for Tech-CBT. This project would suit someone with a background in psychology or health sciences.

Possible Research Projects

Note for students: The possible research projects listed on this page may not be comprehensive or up to date. Always feel free to contact the staff for more information, and also with your own research ideas.

1. PhD Scholarship available: Understanding the barriers and facilitators of delivering a technology-assisted telehealth psychotherapy intervention to people with dementia

As part of the study, we will undertake a process evaluation to assess treatment fidelity, dose and contextual factors that may influence effectiveness, to inform future implementation in community and memory clinic settings. The PhD project will focus on developing the future implementation framework for Tech-CBT. This project would suit someone with a background in psychology or health sciences.
2. Neurobiology of Anxiety in Older Persons: fMRI study
3. Virtual Reality based Psychological Interventions for Parkinson's disease and Dementia

This staff member is a UQ Expert for media in the following fields:

Parkinson's diisease, Dementia, Anxiety, Depression, Virtual Reality, Psychotropic Prescriptions, Residential Aged Care, Cognitive Behaviour Therapy, Mindfulness

They are happy to lend their expertise to your articles or broadcasts and share their research discoveries and insights with the community via media channels.
