PhD in Mathematics (University of Queensland)
Dr 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, Dr Challis was employed at The University of Queensland in a number of roles including as a postdoctoral research fellow, lecturer, and finally as an Australian Postdoctoral Fellow (APD). Dr 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.
Dr Challis has supervised a number of undergraduate students (honours, summer students) and was associate PhD supervisor of Andrew Cramer (conferred 2018, The University of Queensland). 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 Dr. Challis. For more information on Dr Challis's research outputs, see her profiles on Publons, Scopus, Google Scholar or ORCID.
