Dr Britt Koskella
NERC Fellow

Profile

I am an evolutionary biologist working to figure out why pathogens do what they do. Since every organism on earth (even bacteria) are plagued by disease, it seems surprising that hosts haven‘t been able to evolve complete resistance (i.e., that pathogens exist at all) and, at the same time, why all hosts haven‘t been driven extinct by disease.

One explanation is that hosts are engaged in a continual arms race with pathogens, with hosts constantly evolving new ways of resisting pathogens and pathogens counter-adapting to overcome this resistance. This antagonistic coevolution is thought to be one driver of all the great diversity we see on earth.

As a NERC independent research fellow, I am studying the coevolutionary interactions among bacteriophage viruses that infect and kill a bacterial host which is itself a pathogen that infects and kills plant hosts, including horse chestnut trees. I am both using this as a model system to test evolutionary theory and as an applied system to test whether phages are naturally acting as a sort of biological control of the plant disease, decreasing disease symptoms and helping the tree ward off infection. Just like the old expression: the enemy of my enemy is my friend.
