PhD opportunity: Adélie penguin population ecology in the Ross Sea

Adelie penguins are considered an indicator species of ecosystem function. The Ross Sea was recently designated a Marine Protected Area (MPA), which will limit fishing in the area significantly. However, this protection status will be reviewed periodically and could be modified or withdrawn. The research aims to understand population dynamics so that we can forecast outcomes of a range of different management and climate change scenarios, which should contribute to the decision making on the future of the MPA.

Statistical and simulation modelling will be used to explore a subset of the following interdependent processes: foraging movement of breeding adults, chick provisioning and growth, fledgling success, over-winter movements, survivorship and population dynamics. The student will have access to existing data and will participate in at least one field season in the Ross Sea (i.e. 10 weeks at Cape Bird or Cape Adare) to collect new data. Throughout the project, the student will collaborate with a range of scientists with expertise in ecology and statistics.

The successful candidate will enrol in a Ph.D. at the University of Otago under the direct supervision of Dr. Matthew Schofield in the Department of Mathmatics and Statistics. The student will be co-supervised by Professor Phil Seddon in the Department of Zoology, and Dr. Dean Anderson of Manaaki Whenua Landcare Research. Applicants should have a strong background in both ecology and statistics, and satisfy the University of Otago’s entry requirements for PhD study.

A knowledge of Bayesian data analysis is an advantage. The student should have an understanding of statistical modelling and computation.

This position is contigent on the successful obtainment of a University of Otago Doctoral or equivalent scholarship ( The scholarship covers Ph.D. tuition fees for a domestic or international student plus a living allowance of NZ$25,000 per annum for three years. The starting date will be 1 February 2019.

Freemasons scholarship

Malcolm Jones (3rd year Mathematics major) has been awarded a $6000 Freemasons university scholarship, which is awarded nationally to students based on academic merit and commitment to voluntary work in the community. A report in the Star (10/5) shows Malcolm explaining convex geometry and diversities to the deputy grand master Graham Wrigley.

Impact of tourism on whales and dolphins

Research led by University of Otago scientists, including John Harraway, has provided evidence that whale and dolphin watching activities can have detrimental effects on the populations they target.

The study focused on populations of spinner dolphins off the coast of Egypt in sites with no tourism, controlled tourist activity, and uncontrolled tourist activity. In the uncontrolled site, in particular, there is great concern that the dolphins' resting patterns are being disrupted.

The study "Behavioural responses of spinner dolphins to human interactions" has been published by Royal Society Open Science

Johannes Mosig, exceptional PhD thesis

Congratulations to Johannes is also called for. His PhD thesis "Contemporary wave–ice interaction models" is one of this year's Division of Sciences Exceptional Doctoral Theses.

The motivation for studying wave-ice interaction is that it plays a role in understanding climate change, and it is vital to wave forecasting models that have to be accurate to ensure the safety of e.g. research expeditions, coastal communities.

Insight on infinity

The work of Joerg Frauendiener and Joerg Hennig has been given a special feature in CQG+, the companion blog to Classical and Quantum Gravity, the world's leading gravitational physics journal. The Joergs have implemented a fully pseudospectral scheme in space and time that allows them to numerically resolve solutions of a set of gravitational wave equations out to infinity.

Welcome to Dominic Searles

We are delighted Dominic Searles has joined us as a Lecturer in Mathematics. Dominic studied mathematics at the University of Auckland and then completed his PhD at the University of Illinois at Urbana-Champaign in 2015. Afterwards, he was a postdoc at the University of Southern California. He and his family have now decided to come back to New Zealand and have swapped the Californian sun for the more moderate Dunedin climate. Dominic's research is in algebraic combinatorics with a focus on Schubert calculus. A warm welcome to you, Dominic.

Mathematics in Industry

Graduate and undergraduate students in mathematics might find the article What Characteristics Make Mathematicians Suited for Industry useful. While the context is American, many of the observations apply for students working within NZ, where the adjustment is perhaps even more difficult.

Karl Schwarzschild Prize

Vee Liem Saw has been awarded the Karl Schwarzschild Prize for the best overall contributed talk at the 3rd Karl Schwarzschild Meeting in Frankfurt, Germany. This is a remarkable achievement for a PhD student. Vee Liem spoke about mass loss due to gravitational waves in the presence of a positive cosmological constant.

Welcome to Melissa Tacy

We are thrilled to welcome Melissa Tacy to the Department as a Lecturer in Mathematics. Melissa's research lies within the intersection of microlocal analysis, semiclassical analysis and harmonic analysis, and is particularly focused on quantum chaos. Most recently, Melissa was at the Mathematical Sciences Institute at the Australian National University.
