My research centres on identifying processes which contribute
to the genetic structure resident within natural plant populations.
Much of this research is currently directed towards understanding
how impacts such as remnant size, degree of isolation and
level of degradation associated with recent landscape fragmentation
affect plant population viability. This research is utilising
a range of molecular markers to assess levels of genetic diversity
and mating systems as well as demographic assessments and
growth trials. Closely allied with this project is a strong
interest in determining whether fragmentation is also influencing
microbial diversity within the remaining remnant vegetation.
My other interests include developing a framework to assess
species' provenance, particularly for those species commonly
used in the restoration of degraded landscapes. I am also
interested in hybridisation events which have the potential
to threaten species integrity and whether this is exacerbated
by fragmentation and isolation.
