2025 AMSI-ANZIAM Lecture Tour
2025 ANZIAM Lecturer
The AMSI-ANZIAM Lecture Tour invites a distinguished international academic in an applied mathematical field to speak at universities across Australia after the conclusion of the ANZIAM conference. It includes a series of talks including specialist and public lectures. The tour is organised biennially by AMSI and is supported by ANZIAM.
Speaker
Professor Sunghwan Jung, Cornell University
Dr. Sunghwan (Sunny) Jung is a professor in the Department of Biological and Environmental Engineering at Cornell University. Jung received his Ph.D. in Physics from the University of Texas at Austin in 2005. He then worked as a postdoctoral fellow at NYU and MIT before joining the faculty at Virginia Tech and Cornell. His research focuses on fluid mechanics problems arising from the interaction between biological systems and their physical surroundings. His work also encompasses topics related to bio-inspired engineering applications, taking advantage of physical principles derived from his research findings using dynamical system approaches.
Schedule
Prior to the lecture tour, Professor Sunghwan Jung will deliver a plenary talk at the ANZIAM Conference held in Coffs Harbour from 2-6 February 2025.

Talk abstract
Colloquial Lecture: Transport Mechanisms Induced by Raindrop Impact
Plant leaves possess a remarkable ability to adapt and withstand external fluidic stimuli in the wild. Rainfall, in particular, exerts impulsive stress on plant leaves, causing them to twist, bend, and vibrate, leading to the shedding of spores and allergens. These interactions between the raindrop and leaf have raised some intriguing scientific questions and practical applications. Upon impact, air vortices form and play a pivotal role in spore dispersal, with a single raindrop capable of dispersing over a thousand spores. These initial vortices lift spores beyond the boundary layer, enabling them to be carried away by the wind. Subsequently, the vibrating motion of the leaf further induces flow coherence and enhances the transport of spores. Through Lagrangian diagnostics, we have further discovered the presence of hyperbolic and elliptical coherent structures around fluttering leaves, providing a dynamic description of spore transport.
