PhD position in General Relativity

The Relativity group at the University of Otago, New Zealand invites applications for a PhD position in General Relativity, in particular on the gravitational wave emissions of rotating neutron stars. The position comes with a 3-year scholarship which covers tuition fees as well as an annual stipend of 25000 NZD.

The position is related to a Catalyst:Seeding grant from the Royal Society of New Zealand to J. Frauendiener to work on neutron star mountains and their gravitational wave signals. The project is joint with Prof. Andrew Melatos (University of Melbourne, Australia) and Prof. Susan Scott (Australian National University, Canberra) both members of OzGrav, the Australian Centre of Research Excellence for Gravitational Wave Discovery.

We are looking for a motivated person with a degree equivalent to MSc or BSc(Hons) in Theoretical or Mathematical Physics. Good mathematical skills are essential. Prior research experience in General Relativity or relativistic astrophysics is desirable.

The starting date of the position is on 1.6.2018. The position will be open until filled.

Please send applications (including CV and certificates) or enquiries to mailto:joergf@maths.otago.ac.nz.

Honourable mention

Congratulations to Vee-Liem Saw for earning an honourable mention in the Aitken student prize competition at the NZ Mathematical Society's Colloquium. In his talk, "Helicalised fractals", Vee-Liem formulated the concept of the "helicaliser", which must also be one of the best new words of 2015!

Vee-Liem is currently a PhD student being supervised by Jörg Frauendiener and Jörg Hennig.

EINSTEIN 100 years of the theory of general relativity

In collaboration with the Otago Museum we organised an exhibition to commemorate 100 years of General relativity. The official opening is on Saturday 14. November.


Early Career Award for Jörg Hennig

Congratulations to Jörg, a recent recipient of the University's Early Career Awards for Distinction in Research. Jörg's research is concerned with cosmological models, properties of black holes and the application of highly-accurate numerical methods to problems in general relativity. Currently, his main goal is a deeper understanding of unusual cosmologies. See Early Career Awards for more detail of his research and this very worthy achievement.


Teaching Award

During his recent trip back home to Malaysia for the Chinese New Year celebration, Vee-Liem Saw dropped by Singapore and picked up his third consecutive Teaching Award at Nanyang Technological University. He served there as a full-time teaching assistant under the Division of Physics and Applied Physics for three years since August 2011, before beginning his PhD study in September 2014 on gravitation here in Otago. A wide range of physics courses from freshman to advanced undergraduate levels had been taught by Vee-Liem, to students of various backgrounds - comprising physics majors, engineering majors, as well as top undergraduates under the CN Yang Scholars Programme.

NZ Mathematics Society’s Early Career Award 2013

Dr Florian Beyer received the NZ Mathematics Society’s Early Career Award 2013. The award citation reads: “For his contributions to the understanding of the global structure of cosmological solutions of Einstein’s equations using numerical and analytical methods, and, in particular, for the proof of the well-posedness of the singular initial-value-problem for Fuchsian PDEs.”
