Australia's challenges in environmentalsustainability rival those of anywhere else on Earth and for thisreason we must be clever in our diagnosis of environmentalsusceptibility and damage and insightful in all remedies proposed andapplied. Post-doctoral research fellowships are offered in ourInstitute for Nuclear Geophysiology which aims to be an internationalcentre of excellence in nuclear science and technology applied toenvironmental challenges of Australia and the world.

We have 4 opportunities for recent PhD graduates with a stronginnovation focus, good communication skills and a proven publicationrecord. We are seeking researchers who work well within smallmultidisciplinary teams and collaborate strongly with other researchgroups to undertake research in the following areas:

Natural radionuclides in the lower atmosphere. (Reference: PD.1)
Our Isotopic Tracers in Atmospheric Transport project needs you to havea recent PhD in atmospheric or environmental geoscience, physics, mathsor a related field and skills and experience in the measurement ofturbulent exchange processes in the atmospheric boundary layer and/ortheir representation in weather and climate models. On this project youwill measure and model naturally-occurring radioisotopes in the loweratmosphere with an aim to advancing the understanding andrepresentation of turbulent vertical mixing processes on diurnal toseasonal timescales.

Palaeo-climate archive studies with cosmogenic isotopes (Reference: PD.2)
A recent PhD graduate in earth sciences, climate change, environmentalgeoscience, physics or a related field and experimental researchexperience in applications of cosmogenic radionuclides can join ourCosmogenic Climate Archives of the Southern Hemisphere project. On thisproject you will conduct research in paleo-climate variability relatedto applications of cosmogenic and stable isotopes in the study ofglacial geochronologies, solar variability and rates of landscapeprocesses during the Quaternary and last glacial cycle. This work willprimarily be based on measurements at ANSTO's ANTARES AMS Facility ofBe-10 and Al-26 in continental and mountain glacial formations,Antarctic ice cores, ocean and terrestrial sediments and possibly otherarchives.

Bioscientist - Neutron Scattering (Reference: PD.3)
This opportunity is for a recent PhD graduate in a Biological Science,Chemistry or Physics to join our research team working on the‘Characterisation of Biomolecules' Project. We seek a researcher withpractical experience to work with this multi-disciplinary team thatconducts research on the development of biological applications ofneutron and X-ray scattering techniques. The aim of this position is touse neutron and X-ray scattering techniques for elucidating thestructure/function relationships of proteins. The work ismulti-disciplinary, requiring knowledge and experience in biophysicaland/or biochemical characterisation techniques and in application ofneutron and X-ray scattering methods for investigating biologicalsystems including data reduction and analysis.

Research Associate for Nuclear Safeguards (Reference: PD.4)
ANSTO supports the International Atomic Energy Agency's nuclearsafeguards program by providing a specialist analytical service insupport of environmental sampling for detection of undeclaredactivities. Currently we are engaged in developments to improve thesensitivity of the Accelerator Mass Spectrometry system, in particularfor plutonium isotopic analysis, for particle analysis, and for agedating of nuclear materials. For this research opportunity you need arecent PhD in physics or related field, preferably with experience inone or more of the following areas: accelerators, ion beam systems,mass spectrometry, experimental nuclear or particle physics. It is alsodesirable that you either understand or are capable of acquiringexpertise in the following: design and operation of acceleratorsystems, specifically for AMS; principles behind nuclear safeguards andthe nuclear fuel cycle.
We expect the successful applicants will have no more than 3-years postdoctoral experience. Starting salary is negotiable from $54,600 pa plussuperannuation depending upon qualifications and experience. These aretwo-year term roles with a possibility of extension.
