Te Pūnaha Matatini Scholarships

Mapping antimicrobial use

Mapping antimicrobial use

Antibiotics are a cornerstone of modern medicine, used to treat infectious diseases and prevent infection in vulnerable humans and animals. A 2014 report by the World Health Organization (WHO) concluded that within a decade, antibiotic resistance will make routine surgery, organ transplantation and cancer treatment life-threatening.

In this project, we will build a picture of antibiotic use in New Zealand which includes both human and agricultural use. Such a map will highlight potential breeding grounds for antibiotic resistant bacteria that should help in the development of policies to tackle antibiotic resistance.

The project will be part of Te Pūnaha Matatini (TPM), which is the New Zealand Centre of Research Excellence for Complex Systems, Data and Networks, and will be co-supervised by TPM investigators with various backgrounds. Student background and interest could determine some directions for the project, which will be located at the University of Auckland.

Eligibility
This project would suit either a mathematician/computer scientist with an interest in infectious diseases, or a microbiologist/molecular biologist with an interest in computing. Some fieldwork may be involved. Applicants will need to meet the eligibility criteria for the University of Auckland.

Total value
The three-year scholarship covers PhD tuition fees (for a domestic or international student) and a stipend of NZ$27,300 per annum.

The science of science funding

The science of science funding

A PhD scholarship is available for supporting a mathematics, computer science, economics or theoretically inclined physics graduate to study the science of science funding.

Are public research funding mechanisms effective or not? This project involves developing econometric models of the research process that include researchers and projects, with measures of:

  • team formation, by looking at the evolution of collaborations using network analysis;
  • effects of public funding on research outputs, by comparing funded and unfunded projects, controlling for selection bias using referee scores and other evaluation measures;
  • research impact, by linking identified funded projects and researchers to appropriate metrics and indicators of impact.

The PhD project will be carried out under the supervision of Prof Shaun Hendy at the University of Auckland and Dr Adam Jaffe at Motu Economic and Public Policy Research, as part of Te Punaha Matatini, which is the New Zealand Centre of Research Excellence for Complex Systems, Data and Networks.

Eligibility
Applicants should ideally have a First-Class Honours degree in Mathematics, Computer Science, Economics, or Physics (or an equivalent 4-year degree qualification) and satisfy the University of Auckland’s entry requirements for PhD study.

Total value
The three-year scholarship covers PhD tuition fees plus a non-taxable living allowance of NZ$27,300 per annum. The starting date can be anytime from 1 November 2017.

Networks

Networks

Networks can be used to describe many ways that humans (and many other agents) interact, enabling researchers to identify potential disease spread on a network of people meeting, or identify groups of neurons that perform some cognitive task and so are linked together in a brain, or make efficient supply chains for companies that manufacture objects from components made by other companies.

Many interesting networks have been identified as having useful structure, such as the surprising number of people with huge numbers of friends on Facebook (who turn the network into a ‘scale-free’ network) and the short paths that exist between parts of the brain that seem unconnected, making it act as a ‘small world’.

In this project, we will ask two important and related questions about these networks: (1) what are the underlying reasons for these extra features, and (2) how can we utilise them to produce more efficient algorithms on networks of these types? For example, a scale-free network has nodes of very high degree (hubs) and so routing algorithms that produce short paths can be made by connecting nodes to hubs, which connect to other hubs, which then connect to the destination node. However, if the hubs are deluged with traffic, this might become inefficient. We will study these questions for a variety of real-world complex networks, such as biological networks, human interactions, and digital humanities.

Eligibility
The project will suit an applied mathematician interested in algorithms. The successful applicant will have the chance to work with a variety of researchers across Te Pūnaha Matatini with interest in several different areas of application as well as the underlying theory.

Birdsong recognition from automatic recorders

Birdsong recognition from automatic recorders

Identifying birds from their calls is potentially extremely useful, since birds call far more often than they are seen. However, the birds rarely call close to the microphone and there are lots of other sounds (including wind and rain) that are also recorded.

The challenge is to reliably recognise the bird calls under these conditions and to infer the approximate number of birds present in an area from the number of calls. This requires a combination of signal processing, machine learning, study of individual bird species, and statistical analysis.

Eligibility
This PhD project will contribute in some of these areas as part of the AviaNZ project. It would suit either a mathematician/computer scientist with an interest in ecology, or an ecologist with an interest in computing. Some fieldwork with New Zealand species of birds, such as kiwis, will be involved.

Managing climate change risks by finding tipping points

Managing climate change risks by finding tipping points

The development of human civilisation over the past 10,000 has benefited from the most stable climate observable in the geological record. Growing evidence suggests that climate change impacts are already observable and will accelerate in the future, potentially combining with other global change factors to push ecosystems and agriculture toward “tipping points”.

This PhD project will develop and assess data science techniques to detect tipping points and regime shifts using algorithms, such as Fisher information, applied to diverse time-series and spatial data. Emphasis will be placed on identifying overlapping cascades of tipping points that should be considered for dynamic policy and management scenarios.

The project will be part of Te Pūnaha Matatini (TPM), which is the New Zealand Centre of Research Excellence for Complex Systems, Data and Networks and will be co-supervised by TPM investigators with environmental, economic and mathematics backgrounds. Student background and interest could determine some directions for the project, which will be located at either the University of Auckland or the University of Waikato.

Eligibility
Applicants should have a first-class or high second-class Honours or Masters level qualification in a relevant scientific and quantitative discipline, and ideally some experience with ecological, agricultural, or economic datasets. Interest and exposure to policy, management or operations research is also desirable.

Total value
The three-year scholarship covers PhD tuition fees (for a domestic or international student) and a stipend of NZ$27,300 per annum.

Investigating prioritisation strategies and effects in patient pathways

Investigating prioritisation strategies and effects in patient pathways

Patient pathways are complex, involving many steps and the use of resources that are often limited, e.g., surgical teams, or required by many different pathways, e.g., imaging and diagnostics. Prioritising one patient pathway’s access to a resource may have adverse effects for other pathways that also need that resource.

Determining effective prioritisation strategies for patients requires modelling of the complexity of patient pathways, their use of resources, and the effect of different prioritisation strategies. It also requires the consideration of appropriate metrics, in order to define a “good” prioritisation strategy. One of our particular interests is in accumulating priority queues where both acuity and waiting time contribute to a patient’s priority.

Feasible accumulation rates can be chosen to satisfy specified performance objectives for each class, where the objectives are in terms of percentage of patients seen within a prespecified time (metrics common to several health systems, including those in Australia, Canada, and New Zealand). However, such objectives may incentivise bad behaviour, particularly, the “dropping” of patients who have breached the threshold. There is, therefore, also the question of what are the “right” metrics for patient pathways.

This project will develop a portfolio of possible metrics for health care provision and within each metric, develop analytical methods for modelling the system performance and optimising patient flows. The aim of this work is to provide recommendations on prioritisation of patients, both tactical (how to route) and policy-based (how to measure) for patient pathways.

Eligibility
This project requires a strong mathematical background, with knowledge of probability and stochastic processes.
