PhD University College Dublin (2012)





Rosie completed her PhD at University College Dublin in 2012. Her work focused on evaluating candidate biological control agents for the submerged aquatic invasive weed Lagarosiphon major. During her PhD she became interested in the use of molecular approaches in biological control including the identification of genetically distinct populations, tracing the origin of invasive pest populations to identify potential biocontrol agents that are compatible and the development of improved recombinant natural enemies. Her work focusses on understanding the genetic structure of potential biological control agents in their native range. This information can then be used to identify populations that exhibit local adaptations to environmental conditions and organisms with which they interact.
