Research Summary

The goal of the work in the Ernst Laboratory is to contribute to the eradication of tuberculosis, by understanding the mechanisms and limitations of immunity to tuberculosis and developing ways to make the immune response more effective. We develop and apply new tools adapted from immunology and bacterial genomics to study the impact of human immune responses on evolution of the bacteria, and use the information to inform new approaches to vaccine development. We also manipulate the bacterial genome, together with genetically-engineered mice, to obtain a deeper understanding of the mechanisms used by M. tuberculosis to evade recognition and elimination by host immune responses.
