Your next career opportunity The position offers opportunities for a highly motivated postdoctoral researcher to take on a major role in the search for inflationary gravitational waves as part of the South Pole Observatory. Working alongside A/Prof Christian Reichardt and international collaborators, you will contribute to precise measurements of gravitational lensing signals in the cosmic microwave background using the South Pole Telescope. These measurements will be used to remove the lensing contributions and thereby enhance the sensitivity to inflationary gravitational waves. A fraction of the time will be available for independent research projects. This role gives you the chance to work with international experts, access world-class facilities, and further develop your research skills in a supportive academic environment. Your responsibilities will include: Conduct Innovative Research: Contribute significantly to the team's research efforts, focusing on CMB analysis and gravitational lensing. Publish and Present Findings: Produce high-impact academic papers and present research at international conferences and seminars. Collaborate Globally: Work closely with international co-Investigators on the South Pole Telescope and BICEP Array projects. Support Student Development: Contribute to teaching and supervision of research students, primarily at the g raduate level. You may be a great fit if: You are a highly motivated researcher with a PhD in astrophysics or a related field, possessing strong analytical skills and experience in CMB analysis, particularly in gravitational lensing and delensing. You may also: Have a PhD in astrophysics, cosmology, or a closely related field. Possess experience with CMB analysis, especially gravitational lensing and delensing. Demonstrate a strong publication record in high-impact journals. Have excellent communication skills and the ability to work collaboratively in an international team. Show enthusiasm for engaging in public outreach and science communication activities. For further information please refer to the attached PD. What we offer you!
