Environmental Health

The Environmental Health team is focused on the establishment of a strong repository of evidence- based research on a range of issues impacting population health. The multidisciplinary team of researchers brings expertise in designing and conducting rigorous epidemiological research studies across India. The team comprises public health experts, epidemiologists, biostatisticians, social scientists, environmental epidemiologists, exposure science experts, geospatial analysts, health economists, health system specialists, nutrition and laboratory science experts.

Current large-scale epidemiological studies are focusing on air pollution, nutritional and psychosocial determinants and climate change and their impacts on a range of child and adult health outcomes. Unique AI- based modelling techniques have been used to develop exposure metrics and dashboards that can be effectively used by researchers in future epidemiological research on population health in India.The team also contributes to the formulation of programs and policies by national and sub- national governments, besides focusing on building capacity for research and advocacy. Several international collaborations also provide a platform for knowledge exchange and training opportunities for early and mid- career researchers, thereby helping to build a pool of future research scientists.

The UK-India Environmental Noise and Health Research Workshop 2026, New Delhi

A one-day research workshop organised by CCDC in partnership with the University of Leicester and the Royal Society is the first-ever initiative to systematically investigate noise exposures and health outcomes in India. A one-of-a-kind workshop, it brought together researchers to share their work, align methodologies, and identify next steps for future collaboration. International collaborators presented comparative findings from the UK and other LMIC settings, enriching the discussion with cross-regional perspectives on noise and health research.
