In early 2015 Tracey joined the EAS group from The University of Melbourne, where she was a Research Fellow associated with the ARC Centre of Excellence in Environmental Decisions (CEED), and the National Environmental Research Program (NERP) Environmental Decisions Hub.  Tracey’s research interests are broad and span the fields of  applied quantitative ecology, conservation biology, ecological risk assessment, and the application of decision theory to the management of threatened and invasive species, and conservation planning more broadly.  Previously Tracey held post-doctoral fellowships at the National Oceanographic and Atmospheric Administration (NOAA) research centre in La Jolla, California, and at the University of Queensland.

Tracey’s current research focuses on two main themes.  The first deals with robust prediction and decision strategies for managing extinction risk under climate change, while the second involves the development and testing the performance of a new global standard for risk assessment of ecosystems:  This latter work supports the IUCN Red List of Ecosystems, and is a major collaboration with scientists from many other institutions.  This project was awarded the prestigious 2015 Eureka Prize for ‘Research and Innovation’.

Tracey’s work in conjunction with other members of the EAS group focusses on the development of an innovative decision support system that will assist DELWP in the allocation of resources for conservation planning and management activities.
