Research interests

My research interests are generally focused on using DNA sequence data to understand ‘how and why species diverge’. For my PhD, I am studying a group of flowering plants called Argyranthemum or more commonly marguerite daisies, which are endemic to the Canary Islands and Madeira. This group represents a classic example of an evolutionary radiation that is typical of remote oceanic archipelagos.

Of particular interest to my PhD is an evolutionary phenomenon termed homoploid hybrid speciation, the origin of a new species following hybridisation without a change in chromosome number. This mode of species formation is thought to be rare in nature and it is poorly understood. Two putative cases of homoploid hybrid speciation can be found in Argyranthemum in A. sundingii and A. lemsii.

Using Next Generation Sequencing technology (transcriptomics) I am investigating the genetic basis of homoploid hybrid speciation as well as the evolutionary processes leading to the diversification of the entire group.

Using transcriptomics to understand adaptation and speciation in an island radiation

This studentship will use a homoploid hybrid Argyranthemum species from the Canary Islands as an exemplary scenario with which to investigate the genomics of adaptation, reproductive isolation and hybrid speciation.
