MrNandakumar Ravichandran

I am a Researcher and PhD Candidate in Medicine at the School of Medicine, University College Dublin, with research interests spanning primary care, hospital medicine, infectious disease epidemiology, cardiovascular health, and public health. My work focuses on generating and applying evidence to improve clinical care, strengthen health systems, and support more integrated approaches across primary care, secondary care, and public health.

My current PhD research focuses on the epidemiology, burden, and outcomes of community-acquired sepsis in Ireland, with a particular interest in improving the early recognition and management of sepsis in general practice. My research examines patient pathways across general practice, emergency departments, and hospitals, as well as longer-term outcomes following sepsis. I am particularly interested in understanding how patients move through the health system and how earlier recognition and better integration between services can improve outcomes.

Alongside my sepsis research, I contribute to multidisciplinary research across cardiovascular health, infectious diseases, addiction services, population health, and clinical research implementation. I am part of the UCD/HSE Dublin South East General Practice Research Network, supporting the development of clinical research and trial capacity across general practice. I have also contributed to international clinical research, process evaluation, and implementation research.

My previous and ongoing research includes work on cardiovascular risk among people with mental health disorders, prevention programmes, virtual wards, early detection models, addiction and substance use, and infectious diseases. I have contributed to both quantitative and qualitative research and have experience working with health data, study implementation, evaluation, and multidisciplinary collaborations across clinical and public health settings.

I am particularly interested in research that bridges the gap between evidence, clinical practice, and health policy, translating data and research findings into practical improvements in healthcare delivery and population health.
