Komal Nayak

Senior Scientist/Laboratory Manager

Komal Nayak completed her BSc (Hons) in Biomedical Sciences in 2007 and an MSc by Research in 2010 at the University of Central Lancashire, UK. In 2011, she worked at Imperial College London, studying the effects of inflammation on neuronal iron metabolism in Parkinson’s Disease.

Since 2012, Komal has been part of Prof Zilbauer’s group, where she has gained extensive experience with human gut organoid culture models. As a Senior Scientist, she leads projects related to gut organoids, including their molecular profiling, the development of a biobank, and functional assays. Over the decade, she has successfully established a large living biobank, housing over 1,000 frozen organoid lines, a vital resource for ongoing research. Her research focuses on understanding the role of epigenetic mechanisms in regulating intestinal epithelial stem-cell function in both health and disease, particularly in the context of Inflammatory Bowel Diseases.
