Australian mathematicians rise to the challenge of COVID-19

(This is a guest post by Dr Joel Miller, introducing a miniseries of articles/essays by Australian mathematicians involved in the pandemic response)

Mathematics plays an integral role in our daily lives.  A smart phone that guides you to your destination relies on mathematical routines to calculate your position, other algorithms find the optimal route, and yet others ensure that the communications from your phone are secure.  The central role that mathematics plays throughout scientific disciplines comes largely because our mathematical models of the natural world, built on observation, give us remarkable predictive power and allow us to design systems that perform optimally.

At the outset of the COVID-19 pandemic, we did not have time to do careful experiments comparing different policies before implementing them.  What we had was information about how efficiently the disease spreads, some hints that it could spread through asymptomatic or presymptomatic infected individuals, and estimates of the distribution of severity in different age groups.  That knowledge grew as different countries began to experience outbreaks.

Armed with this knowledge policy makers were forced to make decisions about their response.  They needed a way to turn this limited information about the mechanisms underlying disease spread into projections of what the future would hold.  Mathematical modelling was the tool that let us rigorously determine what consequences could follow from different policy decisions and different plausible disease properties.  The modelling effort relied on a wide range of techniques and modellers from different backgrounds and career levels, ranging from student to senior academic, as well as researchers working within health departments.

Lives have been upended by the COVID-19 pandemic, and by our response to it.  In this series some of the mathematical modellers who played a role in advising Australia’s (thus far) stunningly successful response give their perspective on the role that they played, showing how mathematicians at many levels played a key role in the decisions that led to COVID-19’s effective elimination in Australia.

PhD Top-up Scholarships: Ocean and Sea Ice Modelling

Closing date: 30 November 2021

Are you interested in understanding ocean physics, and do you have skills in computational/mathematical modelling?

The Consortium for Ocean-Sea Ice Modelling in Australia (COSIMA) is providing opportunities for PhD
students to work at the intersection of high-performance computing and ocean-climate dynamics.
Projects are available focusing on a wide range of topics, including:

  1. The role of sea ice in the climate system;
  2. Modelling biogeochemical cycles in the global ocean;
  3. Coupling between surface waves and large-scale currents;
  4. Antarctic ice shelves and their interaction with the Southern Ocean; and
  5. The sensitivity of ocean dynamics to vertical coordinate systems in ocean models.

These scholarships are valued at $7,500 per year for 3.5 years. Successful applicants will also need to be
successful in receiving a Research Training Program (RTP) scholarship, or equivalent primary scholarship,
at a COSIMA partner university (ANU, UNSW, UTas, USyd, UniMelb or U Adelaide).

To Apply, you should submit a package to Ms Alina Bryleva including:

  • A half-page statement explaining your research interests and your planned work with COSIMA.
  • Your CV and academic transcripts.
  • Provide amount and source of any existing scholarships, both top-ups and a primary stipend.

These top-up scholarships are intended primarily for new students, however existing students working on one of the COSIMA models will also be considered. Preference will be given to competitive applicants who do not already receive a top-up scholarship from another source.

4-year industry PhD scholarship+top-up on online misinformation detection@Uni Adelaide

School of Mathematical Sciences, University of Adelade

Closing date: COB 28 October 2021

The spread of misinformation online is believed to be driven in part by non­human actors: algorithms and bots, often coordinated offshore. Recent research has developed algorithms for identifying such bots through measures of coordination: accounts that post to social media at similar times, or with similar, recognisable patterns of behaviour. State-of-the-art approaches to bot detection nonetheless use relatively naive social media analytics and measures, and not using the full extent of information (e.g., network structure and full post content) available. This project will develop new measures of social information flow to understand the extent of online social influence, and build new tools to counter malicious coordinated behavior, in real time.

4-year PhD stipend ($28,597 p/a) plus $12,500 p/a (Supplementary Scholarship, indexed annually); includes internship with Defence Science and Technology Group (DSTG). Applicants must be Australian citizens able to obtain security clearance. Applications for this UAiPhD project should be submitted to Associate Professor Lewis Mitchell by no later than COB 28 October 2021.

PhD top-up scholarship suitable for applied maths/stats@ANU

Computational methods for pupil-based disease diagnostics

Pupils are a diagnostic window onto the eye and brain circuits that govern their movements and hold the promise of contactless disease screening. However, the journey from pupil response to disease biomarker is a challenging road paved with complicated computational methods and ingenious visual stimulus design. A biomarker refers to a characteristic that is objectively measured and evaluated as an indicator of normal biological processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention (US National Institutes of Health. Biomarkers Definitions Working Group, 1998). When combined with computational methods to allow systematic data analyses at scale to discover disease, immune, and treatment-response signatures, biomarkers can be used to develop novel diagnostics.We seek a PhD candidate with a background in computer science, computational neuroscience, or applied mathematics to join a multidisciplinary team developing novel algorithms that transform pupil-diameter time series to biomarkers for disease. Students with strong analytic and programming abilities combined with an interest in solving big health problems through engineering are encouraged to apply.The position would jointly supervised by Dr Elena Daskalaki and Dr Josh van Kleef and attract a generous top-up scholarship of $10K p.a. for 3 years provided by our commercial partner (Konan Medical USA). It is expected that suitable candidates would have qualified for an Australian Postgraduate Award or equivalent scholarship for international candidates.This research will be delivered in partnership with Our Health in Our Hands (OHIOH), a strategic initiative of the Australian National University, which aims to transform healthcare by developing new personalised health technologies and solutions in collaboration with patients, clinicians, and health care providers. Research undertaken by the group has already resulted in a number of patents, so there is strong potential for commercial applications arising from this project.
