Research
I am interested in many facets of plant systematics and evolutionary biology, particularly in relation to the northern Queensland flora. I am currently investigating the systematics of fern and lycopod groups and the origins of their diversity in Australian to improve the systematic treatment of the Australian representatives. I am also interested in the biology of vascular epiphytes, niche specialisation among epiphytes and causes of rarity. I am the curator of fern and lycopod families at the Australian Tropical Herbarium (ATH) and co-curator at the Queensland Herbarium (BRI).
Current projects:
-
Mixed-model Bayesian inference phylogenetic analysis of genetic and phenotypic datasets to testgeneric concepts within the Lycopodiaceae and in particular the placement of ‘tassel-ferns’.
-
Mixed-model Bayesian inference phylogenetic analysis of genetic and phenotypic datasets to investigate the species diversity of Palaeotropical tassel-ferns and the origins of the Australian species and species boundaries in the H. phlegmaria group.
-
Investigating the type and cause of rarity in the endangered blue-tassel-fern Huperzia dalhousieana
-
Resolving systematic problems in target fern and flowering plant groups present in tropical Queensland
-
Reassessment of the conservation status of lycopods, ferns and orchids for the Nature Conservation Act 1992
-
Development of a LUCID key to the identification of ferns and lycopods in tropical Queensland
