I apply global dynamic vegetation models (e.g. LPJ-GUESS), and several bioclimatic envelopes (correlative based models) to examine the impacts of future and palaeo climate change on surviving Australian species and the extinct ones.
I try tracing the role of environmental fluctuations on the evolution of Australia’s natural history (vegetation communities) over spatial times scales (e.g. 200,000 years back).
Why I do this? It is simple, if we understand how did Australia’s endemic biota respond and adapt to periods of prolonged climatic stress, we can learn lessons that will help Australia’s environment and society in the future. For example, one of my palaeoclimate change studies (under review) showed that under future climate warming (increasing wildfire) and increasing CO2 concentration, we might expect more forest in some areas by the end of the century, but it is uncertain due to several reasons (e.g., human-driven fire, landscape clearance, invasive species, etc.).
During the past postdoctoral research opportunities, the most significant aspects of my research career were to assess the extent of suitable habitat for ~300 species (invasive, naturalised, and non-native plants) in Australia under current and future climate conditions, to investigate how projected changes in climate might alter the distribution of these species in the coming decades.
As part of the Which Plant Where? research program, my responsibilities include:
- vegetation modelling
- co-supervision of students
