Working in theoretical atomic physics and particle astrophysics. My research focusses on high-precision atomic structure calculations, and how atomic processes can be used for testing fundamental theories, probing for physics beyond the standard model, and searching for dark matter. This is complimentary to the high-energy tests performed at CERN. Some research highlights include: searching for variations in the fundamental constants near the super-massive black hole at the centre of our galaxy [1]; using decades of archived atomic clock data from the GPS satellites to search for signatures of dark matter [2]; performing high-precision calculations of symmetry violations in atoms, allowing the most precise low-energy test of the standard model to date [3-5]; and proposing and quantifying novel experimental signatures of dark matter that exploit atomic (rather than the typical nuclear) phenomena, opening the door to a wide range of previously “invisible” models [6-10].

Professor Jennifer Stow is a molecular cell biologist, an NHMRC Leadership Fellow and head of the Protein Trafficking and Inflammation research laboratory in The University of Queensland’s Institute of Molecular Bioscience (IMB). Her previous leadership appointments include as Division Head and Deputy Director (Research) at IMB (12 years) and she currently serves on national and international advisory boards, editorial boards and steering committees, and as an elected Associate Member of the European Molecular Biology Organisation (EMBO).

Jenny Stow received her undergraduate and PhD qualifications at Melbourne’s Monash University before undertaking postdoctoral training in the Department of Cell Biology at Yale University School of Medicine, USA. With training as a microscopist in kidney research, she gained further experience at Yale as a postdoc in the lab of eminent cell biologist and microscopist, Dr Marilyn Farquhar, where protein trafficking was both a theme and a passion. Jenny then took up her first faculty appointment as an Assistant Professor in the Renal Unit at Massachusetts General Hospital (MGH) and Harvard Medical School in Boston USA, where her research uncovered new roles for a class of enzymes, GTPases, in regulating trafficking within cells. At MGH her research also formed part of a highly successful NIH Renal Cell Biology Program. In late 1994, Jenny moved her research lab back to Australia, to The University of Queensland, in late 1994 as a Wellcome Trust International Medical Research Fellow. As part of IMB since, the Stow lab has continued a focus on protein trafficking, including pioneering live-cell imaging, to spearhead their work on trafficking in inflammation, cancer and chronic disease. Major discoveries include identifying new proteins and pathways for recycling adhesion proteins in epithelial cells, inflammatory cytokine secretion in macrophages and immune signalling through Toll-like receptors in inflammation and infection. Small GTPases of the Rab family, signalling adaptors and kinases feature among the molecules studied in the Stow lab for their functional roles and their potential as drug targets in inflammation and cancer. A keen focus is to understand the role of the fluid uptake pathway, macropinocytosis, in controlling inflammation, cancer and mucosal absorption.

Professor Stow has been awarded multiple career fellowships including from American Heart Association, Wellcome Trust and NHMRC. She has published >200 papers, cited over 15,500 times and she is the recipient of awards and honours, most recently including the 2019 President's Medal from the Australia and New Zealand Society for Cell and Developmental Biology. She is also academic head of IMB Microscopy, a world-class fluorescence microscopy and image analysis facility. Her research is funded by a variety of agencies and industry partnerships, in addition to NHMRC and ARC, including through the ARC Centre of Excellence in Quantum Biotechnology, QUBIC. The Stow lab work with national and international collaborators and welcome students and postdoctoral trainees to participate in their research. We value having a diverse, inclusive and supportive culture for research and celebrate the many diverse and wonderful successes of Stow lab alumni.

I am a media studies scholar studying current smart technologies and consequent ontological conundrums we face as these machines become smarter than us at telling how things are within ourselves and around our worlds. My previous research on the Internet of Things (IoT) was about these hidden arrangements of things in our background that machines constantly remind us of as those we should always be a little paranoid of, and how this normalized paranoia leads us to accept the IoT as a new smarter technique of self-governance. My first book Internet-ontologies-Things: Smart Objects, Hidden Problems, and their Symmetries (2023) argues these popular narratives of smart lives as our strategic and speculative responses to such common feelings: "Something is there, so embedded in our bodies, homes, and neighbourhoods. We feel it but cannot grasp it!"

Digital ontology is the term that best describes the nature of my research but it's less relevant to a pure philosophical inquiry about how things are in the world. Ontology in my practical and critical concern is rather related to the new capitalist ideology (or realism) that runs media industries’ current speculative economy. So, my critical reading of the ontological turn in humanities and social sciences focuses on its strategic dimension. How does this turn draw our attention to the things that our too-human perception always fails to pay the right attention to? How does this in turn mobilize our constant speculation about things beyond our perceptions and control, not only as the inexhaustible source of our anxieties but also as the inexhaustible resource of cultural production?

My current research interests include Digital Ontology, New Materialism, Speculative (Capitalist) Realism, Quantum Physics as Cultural Imagination, Science and Technology Studies, Actor-Network Theory, French Philosophers (e.g. Foucault, Deleuze, and Badiou), Eco- and Geo-philosophy/criticism, new materialist film and videogame studies.

Dr Alina Bialkowski is a computer vision & machine learning researcher developing interpretable machine learning models to increase the performance and transparency of Artificial Intelligence (AI) decision-making. Her research interests include quantifying and extracting actionable knowledge from data to solve real-world problems and giving human understanding to AI models through feature visualisation and attribution methods. She has applied these techniques to various multi-disciplinary applications such as medical imaging (including imaging strokes in the brain using the new sensing modality of electromagnetic imaging), modelling human attention in driving, intelligent transport systems (ITS), intelligent surveillance, and sports analytics.

Dr Bialkowski holds a PhD and BEng (Electrical Engineering) from the Queensland University of Technology, Australia. Her doctoral studies were in characterising group behaviours from visual and spatio-temporal data to enhance statistics and visualisation in sports analytics as well as intelligent surveillance systems. She spent a year at Disney Research Pittsburgh where she developed techniques to automatically analyse team sports, followed by 2.5 years as a postdoctoral researcher at the University College London, developing deep neural networks to better understand human perception and attention in driving, before joining UQ in late 2017.

The impact of her research is evidenced by the high number of citations to her work (>1600 citations and an h-index of 20 according to Google Scholar) and awards including a best paper prize in 2017 at WACV (a top computer vision conference). In addition to high impact journals and conferences, her work has resulted in 6 international patents filed with Disney Research, Toyota Motor Europe, University College London, and The University of Queensland.

I am interested in low-dimensional geometric topology, with a focus on knot theory, quantum invariants of 3-manifolds, and knot homologies --especially in relation to concordances and 4-dimensional smooth topology. I recently got interested in the deep connections, usually provided by combinatorial algebraic topology, between discrete structures --such as matchings and discrete Morse functions-- and their smooth counterparts. As a side interest, I try to apply techniques from topological data analysis to knot theory.
