Research Interests

The origin of life as the emergence of complex, reproducing, open-ended systems was enabled by evolutionary forces. By combining top-down analysis of evolution at work in modern organisms with bottom-up construction of synthetic evolving systems, I will explore the factors that drive and shape these evolutionary forces.

I am especially interested in experimentally understanding how parasites - including viral parasites of cellular organisms as well as selfish genetic elements in molecular self-replicating systems - may contribute to the evolution of complexity.

In addition to parasite coevolution as a driving evolutionary force during the origin and early evolution of life, am also interested in understanding what forces may drive the emergence and evolution of evolvability.
