Proceedings of the 2022 Computational Techniques and Applications Conference

CTAC 2022 Queensland University of Technology, Brisbane, Australia 29 November – 2 December, 2022 The 21st Biennial Computational Techniques and Appli- cations Conference (CTAC-2022) was hosted by the School of Mathematical Sciences and Centre for Data Science at Queensland University of Technology in Brisbane. The ANZIAM Special Interest Group in Computational Mathematics is responsible for this series of conferences, the first of which was held in 1981. The meeting provides an interactive forum for researchers interested in the de- velopment and use of computational methods applied to engineering, scientific and other problems. Participants of the conference are able to submit a short article based on their presentation for publication in this special section of the ANZIAM Journal (Electronic Supplement). The ed- itors, Tim Moroney, Qianqian Yang, Vivien Challis and Elliot Carr, thank the referees whose efforts have helped improve the quality of these conference proceedings. This Special Section of the ANZIAM Journal (Electronic Supplement) contains the refereed conference papers. The eight keynote presentations were as follows. Chris Drovandi, Queensland University of TechnologyLikelihood-Free Bayesian Inference and Model Mis- specification Jennifer Flegg, The University of Melbourne Mathematical Modelling of Avascular Tumour Growth Frances Kuo, The University of New South Wales Lattice Meets Lattice—Application of Lattice Cuba- ture to Models in Lattice Gauge Theory Christian Lubich, University of Tuebingen Convergent evolving surface finite element algo- rithms for geometric evolution equations Marco Palombo, Cardiff University Perspectives on AI-powered brain microstructure imaging Emilie Sauret, Queensland University of TechnologyA hybrid Lattice Boltzmann approach for simulating viscoelastic instabilities and elastic turbulence Karen E Willcox, The University of Texas at Austin Predictive Digital Twins: From Aerospace Engineer- ing to Computational Oncology Andy Wilkins, CSIROThe Importance of Mathematics The presentation by Andy Wilkins was a public lecture. The conference attracted 76 registered participants, and featured a total of 54 contributed talks.
