Plant-animal interactions in tropical forests- especially seed dispersal, secondary seed dispersal and pollination. For example how different primate species disperse seed and what happens to this seed when their primary disperser becomes rare or goes extinct.
Understanding the evolution of unusual plant breeding systems in tropical trees. For example the evolution of female sterility in the legume Anthonotha noldeae.
Forest restoration- exploration of management techniques to promote forest restoration in Afromontane environments.
The role of hybridisation and speciation in the evolution of invasiveness in plants. In New Zealand invasive plants are a major contributor to biodiversity loss. What makes some species so invasive? Do they evolve this ability through hybridisation after arrival in NZ?
