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.

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.
