NLM’s networks, gene regulation, and chromatin research focuses on diverse aspects of gene regulation, such as chromatin organization, DNA conformation, DNA-protein interaction, DNA regulatory elements, and gene regulatory networks. This area of research includes the role of gene regulation and interaction networks in diseases such as cancer, using big data from new experimental technologies. This often involves the development of new computational approaches and algorithms.
