I am interested in the ecological, evolutionary and metabolic dynamics of guppies. Guppies provide a poster-child example of rapid evolution with one of the traits that can evolve rapidly being metabolic rate. Exactly how metabolic rate evolves is unclear, but it seems probable that mitochondria play a key role as these are the workhorses of cells, creating ATP. My research aims at exploring mitochondrial and metabolic evolution of guppies and providing insight into how such rapid evolution can occur.
