Congratulations to Antony Selvan, who won the Best Student Paper Prize at the 2024 Mathematical Biology Special Interest Group (MBSIG) workshop at the University of South Australia. Antony’s paper, entitled “Point torque representations of ciliary flows” developed new singularity methods for representing the flow fields generated by cilia and flagella. This prize is for an exceptional paper in the field of mathematical biology, and comes with a cash award of 300 AUD, and an invitation to speak at the workshop.
Congratulations to Xinyi Yang for receiving an Honourable Mention in the Thomas Cherry Prize at the 2024 Australian and New Zealand Industrial and Applied Mathematics (ANZIAM) conference. Xinyi’s talk was entitled “Escape motility of multicellular magnetotactic prokaryotes”.
Our preprint posted on bioRxiv, led by Dr. Pranali Deore, uses fluorescence lifetime imaging microscopy (FLIM) and FISH to visualise intracellular bacteria in Symbiodiniaceae. Significant changes in the abundance of intracellular bacteria relative to autofluorescence in B. minutum cells were observed at initiation of light and dark conditions. We suggest that the onset of bacterial endosymbiosis is linked to the photoperiod driven changes in B. minutum life stages.
Our latest work, published in collaboration with colleagues at University of Technology Sydney and ETH Zurich, examines the role of chemotaxis in bacterial interactions. The paper in Trends in Microbiology discusses how chemotactic sensing could represent an important, but largely overlooked, phenotype within bacterial interactions, and play a major role in shaping cooperative and competitive relationships.

Howie Zhou is a Masters student at the School of Mathematics and Statistics. His research investigates ciliary flows generated by coral surfaces, in the presence of non-Newtonian fluids.
Olle is a PhD student (co-supervised with Prof. Madeleine van Oppen) at the University of Melbourne’s School of Mathematics and Statistics. His research topics include motility and chemotaxis of Symbiodiniaceae microalgae, in silico and in vitro studies using microfluidics, and modelling the effect of stressors on the coral holobiont.
Congratulations to Antony Selvan for the first paper from his PhD. This work, published in Physical Review Fluids, employs a point torque (or “rotlet”) model to capture the time-averaged ciliary flow above a planar rigid wall.
Congratulations to Peijing Li for the first paper from her PhD, published recently in Journal of Fluid Mechanics. This work explores the streaming flow generated by a sphere in a fluid undergoing rectilinear oscillation.
Rebecca Rasmussen’s research uses experiments and mathematical modelling to investigate the flow patterns produced by the motion of an aquatic insect, the water boatman, exploring what ecological advantages may be conferred by their specific methods of locomotion.
Xinyi Yang is a PhD student in the School of Mathematics and Statistics at the University of Melbourne. Her research focuses on modelling the navigation of microswimmers under the influence of fluid flows, external fields, and confinement.
