Who we are


Dr Daniel Davis - Principal Investigator

I am the PI for the Delirium and Population Health Informatics Cohort (DELPHIC) study, which tracks cognitive and functional status before, during and after hospitalisation in a population sample of older people.


I am a Wellcome Trust Intermediate Clinical Fellow and Honorary Consultant in Geriatric Medicine. My primary interest is the relationship between delirium and/or acute illness and trajectories of cognitive decline in large population-representative studies.

I am keen to understand these relationships in their broadest sense, from the pathophysiological underpinnings through to the implications for health care policy.



Dr Jo Hornby – Study Manager

I’m currently the Study manager for LINKAGE-Camden study, which involves ensuring the study follows the regulatory and ethical requirements, completed on time and within budget. 


Prior to joining the LINKAGE-Camden team I worked as a trial manager in the e-Health Unit at UCL on a feasibility trial comparing face to face alcohol treatment with supported access to web based treatment for hazardous or harmful drinkers. I have worked at several large pharmaceutical companies in the Clinical Project Manager role and have experience in Phase I to IV clinical trials covering the therapeutic areas of anti-infectives, osteoporosis, oncology, cardiovascular, stem cell therapy and diabetes.

Helen Bowden - Research Practitioner

I am currently a Research Practitioner for Linkage-Camden, my role is to recruit and complete health and cognitive assessments with study participants.


I am an Occupational Therapist originally trained in New Zealand and have many years of experience working in a variety of settings across health and social care. Before joining Linkage-Camden I worked in a Diagnostic Memory Clinic contributing to the diagnostic process for people experiencing cognitive impairment, dementia and delirium. I enjoy working with older people and hope the Linkage-Camden study will provide knowledge that will improve health outcomes and help patients to re-gain independence after leaving hospital.


Katrin Hoffmann – Research Practitioner

Along with my colleague Helen, I’m working as a Research Practitioner for the LINKAGE-Camden study, which involves recruitment and cognitive assessment of study participants. 


Prior to joining the LINKAGE-Camden team, I worked as a UCL Research Practitioner for the 100,000 Genomes Project. I was responsible for the coordination and facilitation of England-wide recruitment of patients with Early Onset and Familial Parkinson’s.

I have a background in nursing (NMC RN) with >10 years of experience in different medical disciplines in Germany and Austria, and I volunteered as a medical professional in humanitarian aid missions (Haiti, Brazil, Philippines). I am a Graduate Psychologist (MBPsS) with an MSc in Cross-Cultural Psychology, and I gained research experience in Austria, Ethiopia, Tanzania, and the UK. I am interested in traveling and languages and enjoy the interaction with our culturally diverse study participants.

Maryse Weston-Clarke - Research Assistant

Along with Nell, I conduct the initial assessment with participants either over the phone or in their home. The assessment involves answering questions about your health, memory and any disabilities


Before joining Linkage-Camden I worked for the Islington Services for Ageing and Mental Health as a Dementia Navigator. My role was to signpost service users to support services across the borough of Islington. I have also set up and ran a carer's group for family and friends of those living with Dementia. I have also worked within acute mental health services and charities. I studied Psychology with minor Philosophy at Manchester Metropolitan University and originally hail from Derbyshire.



Nell Green - Research Assistant

Along with Maryse, I conduct the initial assessment with participants either over the phone or in their home. The assessment involves answering questions about your health, memory and any disabilities.


Before joining LINKAGE-Camden I was working at Age UK, providing support and information to the public about their services. I have an MSc in Gender and have conducted research on the older LGBTQI+ community, and how their care needs might differ particularly in relation to end of life care and dementia.


Ashley Smaje - Clinical Research Fellow

My role within the LINKAGE-Camden study is to recruit and complete our health and cognitive assessments with our participants.


I am a junior doctor taking a year out of training to complete research, under a fellowship funded by University College London Hospital. I divide my time between LINKAGE-Camden and a couple of other projects. I am an aspiring geriatrician as I really enjoy working with older people and balancing the complex health needs that arise as we age. My research is focussed around the health of older people, in particular the problems that arise with polypharmacy.
