My research addresses plant population genetics and ecology. I am particularly interested in how genetic processes interact with demography to influence population viability, particularly in fragmented populations. Project areas include basic research on effects of genetically controlled self-incompatibility systems on mate availability, the role of inbreeding in determining the viability of fragmented populations, genetics and ecology of rare and endangered species, provenance studies of common shrubs and trees for restoration and ecological risk assessment of GMOs. My research employs a broad range of techniques including the use of molecular genetic markers, demographic monitoring, growth experiments and simulation modeling. I also teach conservation genetics at in the School of Resource and Environmental Management at the Australian National University, where I am an Adjunct Senior Lecturer.
