Computational Systems Biology of Infectious Diseases

We develop discovery platforms that enable experimental and computational biologists use our approaches to study the molecular basis of pathogenesis and intervention of infectious diseases.

We welcome collaborations: if you are interested in studying an infectious disease/pathogen using our platforms or if you would like to see your computational tool incorporated into our platforms, do get in touch.
