Current activities

Dr Helen Murphy is a senior research scientist with CSIRO Ecosystem Sciences and is the Officer-in-Charge of Atherton’s Tropical Forest Research Centre in North Queensland, Australia.

Dr Murphy leads the Tropical Ecology team in Atherton.

Her team addresses species, population and community level processes driving tropical forest dynamics. 

The Tropical Ecology team manages a series of permanent 0.5 ha rainforest plots across the Wet Tropics where vegetation dynamics have been monitored for the past 40 years. 

The data from these plots, and from the new 25 ha  Rainforest Supersite, is being used to understand the impact of natural disturbances and climate change on tropical forest dynamics.

Dr Murphy’s research interests include the broad spatial and temporal scale patterns and processes driving species distributions and dynamics, including invasive species. 

Dr Murphy’s work on invasive species in the Wet Tropics includes a comprehensive research program aimed at identifying the impacts of current and future invasive weeds on biodiversity.

Her work aims to inform land-managers on pro-active and strategic approaches to optimise long-term management efficiency and costs.  

Current projects and research interests include:

  • understanding weed risks and responses in the Wet Tropics and improving weed management decision making
  • monitoring and analysis of long-term rainforest dynamics
  • determining adaptation strategies to mitigate the impacts of climate change on biodiversity
  • understanding drivers of the distribution and abundance of species
  • biomass supply for sustainable biofuel production systems in the tropics.

Dr Murphy's major research focus is on the dynamics of tropical forests and understanding threats to their structure and functioning

Background

Dr Murphy joined CSIRO in May 2005 as a Weeds Cooperative Research Centre (CRC) Postdoctoral Fellow after completing her doctoral research in Canada. 

Her doctoral research examined the applicability of classic theories and current frameworks for understanding regional-scale population dynamics of plants across their geographic range.

During her Doctorate she was lab instructor, tutor and occasional lecturer for students in biology, plant ecology and evolution.

Prior to undertaking her Doctorate, Dr Murphy worked as an environmental consultant in Townsville, Gladstone and Perth, Australia, primarily undertaking environmental impact assessment for major developments.
