Dr. Sandrama Nadan

Sandrama Nadan is a South African researcher specializing in molecular epidemiology and public health virology, with a strong focus on viral gastroenteritis in young children. Affiliated with national surveillance initiatives, her work has contributed to understanding the burden and evolution of enteric viruses in the post-vaccine era. She has also engaged in interdisciplinary research addressing complex public health systems challenges.

Her publications center on rotavirus, norovirus, astrovirus, and human bocavirus, exploring viral diversity, recombination, genotype replacement, and clinical correlations in hospitalized pediatric populations. Through whole-genome sequencing and molecular surveillance, she has clarified evolutionary dynamics before and after vaccine introduction and highlighted the importance of sustained genomic monitoring in South Africa.

Beyond virology, her recent work applies complex systems thinking to urban sanitation, linking environmental infrastructure with health risks. This combination of laboratory-based molecular expertise and systems-oriented public health analysis underscores a research profile that bridges pathogen genomics, epidemiological surveillance, and policy-relevant health systems research.
