Research
I am an evolutionary biologist and virologist with a strong research focus on emerging infectious disease. My research focuses on determining the fundamental patterns and processes of viral evolution, ecology and emergence.
My research involves using metagenomics to reveal the diversity, structure and evolution of the virosphere; examining the evolution of major viral infections; and developing new analytical and computational approaches to analyse aspects of the virus evolution.
