Summary
This project is based upon the observation that the mammalian immune system can distinguish between its own genetic material (DNA) and the genes of infectious agents such as bacteria. This fact has implications for understanding how the immune system copes with infection, and also for design of new therapies and vaccines. Our central aim is to define exactly how this recognition system works. The cells that respond most vigorously to foreign DNA are large white blood cells called macrophages.

This fact has implications for understanding how the immune system copes with infection, and also for design of new therapies and vaccines. Our central aim is to define exactly how this recognition system works. The cells that respond most vigorously to foreign DNA are large white blood cells called macrophages. We aim to find the macrophage protein which binds to foreign DNA and triggers the activation of the immune system. The type of immune responses initiated by foreign DNA may be useful in treatment of allergies and cancer and for improving vaccinations.Read moreRead less
I am a molecular and cellular biologist with particular interest in understanding the regulation of DNA damage surveillance pathway and its role in the maintenance of genome stability.
As women age, the quality of their eggs decline and their chance of having a healthy baby plummets. The accumulation of DNA damage within the egg, and the reduced ability to repair this damage, may be one cause of compromised reproductive success in older women. This project will investigate the ability of eggs to repair DNA damage during maternal aging and will explore the importance of DNA repair to fertility and the transmission of high quality genetic material to their offspring.
