Provost’s Chair and Assistant Professor of Molecular Medicine
Lee Kong Chian School of Medicine

Assistant Professor Sanjay Haresh Chotirmall graduated from the Royal College of Surgeons in Ireland (RCSI) with an honours degree and the colleges’ gold medal in Microbiology. He completed his clinical training in Respiratory and Critical Care Medicine across multiple hospital sites in the Republic of Ireland. As a clinician-scientist, his research interests include microbiome medicine, respiratory and critical care including in particular pulmonary infections.

Research Statement

I focus on translational respiratory based research that aims to take questions from the bedside, answered at the bench with a return to implementation at the bedside. I hope to improve patient care and outcomes particularly in Asian populations where little research on lung disease has been performed to date. Applying multi-omic technologies and endophenotyping to achieve precision medicine implementation for respiratory and infectious disease is a key area of interest and application in my laboratory.

GOAL 3: GOOD HEALTH AND WELL-BEING – Ensuring healthy lives and promoting the well-being for all at all ages is essential to sustainable development.
GOAL 10: REDUCED INEQUALITIES – To reduce inequalities, policies should be universal in principle, paying attention to the needs of disadvantaged and marginalized populations.
GOAL 17: PARTNERSHIPS – Revitalize the global partnership for sustainable development.
The Sustainable Development Goals (SDGs), also known as the Global Goals, were adopted by all United Nations Member States in 2015 as a universal call to action to end poverty, protect the planet and ensure that all people enjoy peace and prosperity by 2030.
