Tomasina Oh

I am currently a Dementia Capacity Building Fellow based at the University of Plymouth in England, supported by a fellowship funded by the National Institute of Health & Care Research (NIHR) Applied Research Collaboration South West Peninsula (PenARC) and Alzheimer’s Society. I was born in Malaysia where I received my early and undergraduate education (Language and Linguistics); I read for my M.Phil (Linguistics) and PhD (Experimental Psychology) degrees at the University of Cambridge. I have lived and worked in Malaysia, Singapore and England.

Research interests

My early research was on language impairment in people with schizophrenia, which later evolved to include bilingualism – motivated by moving from England back to Malaysia and then Singapore after my PhD where almost everyone is at least bilingual. In the last five years I have been part of the D-PACT team (Dementia PersonAlised Care Team). This is a programme of research funded by the NIHR to develop and evaluate an intervention comprising a dementia support worker based in primary care. The D-PACT dementia support worker is trained to take a coaching-inspired and person-centered approach to supporting people with dementia and their unpaid carers; they provide ongoing, variable-intensity support in a range of areas depending on what matters to the person with dementia and carer as well as needs. This could include: anticipatory care, physical health, emotional and mental wellbeing, future planning, signposting, and being a single point of contact. As part of D-PACT I also worked on (i) developing and enhancing ways of including people with dementia in research as well as collecting data from them in a person-centred manner; and (ii) employing alternative methods to the randomised controlled trial and realist economic evaluation. My current interests within dementia care include advance care planning (ACP) and issues around this – e.g. taking a systemic approach to achieve better integrated care; the economics of ACP using a realist economic lens and the impact of uncertainty (prognosis/trajectories + multiple long-term conditions) on people initiating planning for the future. I have a developing interest in the use of citizen science and AI in healthcare. I am keen to develop international links and collaborations further.
