Biography
Associate Professor Vivien Challis completed her PhD in Mathematics at The University of Queensland in 2009. Her research interests lie in structural optimisation, computational mechanics and high performance computing. After completing her PhD, she was employed at The University of Queensland including as an Australian Postdoctoral Fellow on a Discovery Project funded by the Australian Research Council.Associate Professor Challis joined Queensland University of Technology in May 2019 as a Lecturer in Applied and Computational Mathematics. She was promoted to Senior Lecturer in November 2021, and to Associate Professor in August 2024. Associate Professor Challis developed and teaches the first-year calculus unit MXB105 and teaches half of the second-year computational mathematics unit MXB226 at QUT. She was the inaugural Director of QUT's Mathematics Summer School for high-school students for 2022-2024.
Associate Professor Challis is lead Chief Investigator of a 2022 Australian Research Council Discovery Project that aims to optimise piezoelectric metamaterials for robotics applications. Associate Professor Challis's research contributions were recognised with the award of the 2024 JH Michell Medal from Australian and New Zealand Industrial and Applied Mathematics. For detailed information on her research outputs, see her profiles on Publons, Scopus, Google Scholar or ORCID.
Associate Professor Challis has supervised a number of undergraduate students (honours, summer students), and has supervised one MPhil and one PhD student to completion. Prospective honours, masters, PhD or vacation research students who are interested in structural optimisation, material modelling, high performance or GPU computing are encouraged to contact Associate Professor Challis via email.
