Research Experience 

Current and recent areas of work include:

• Community-acquired sepsis in Ireland: examining epidemiology, disease burden, patient pathways, emergency department presentations, GP referrals, and longer-term outcomes, including post-sepsis syndrome.
• Infectious diseases and global health: contributing to research examining comorbidities among people who use drugs living with HBV/HCV in Ireland and process evaluation on metformin among people living with HIV and pre-diabetes in sub-Saharan Africa.
• Addiction and substance use: contributing to research on opioid use, dependence, and addiction behaviours, as well as research involving agonist opioid treatments.
• Clinical research capacity in general practice: contributing to the UCD/HSE Dublin South East General Practice Research Network and supporting the development of clinical trial capacity across primary care.
• Cardiovascular health: contributing to research examining cardiovascular disease risk among people with mental health disorders and evaluating approaches to cardiovascular risk prevention and management.
• Population health and health-system innovation: evaluating models including Virtual Wards and a pre-clinic vital signs assessment pilot aimed at supporting earlier detection and improving patient care.
• Population health needs assessment: contributing to work mapping health needs across the HSE Dublin & South East region.

Collaboration

My work involves collaboration across general practice, hospitals, public health, academia, and national health organisations. I have contributed to research collaborations with the HSE, Health Protection Surveillance Centre, addiction services, the National Nutrition Surveillance Centre, and clinical partners.
