Our regular seminar program covers a broad range of topics from applied mathematics, pure mathematics and statistics. All staff and students are welcome. This page has a complete list of past seminars and a list restricted by year can be accessed via the left-hand menu.

Wenbo Wu & Jörn Callies - Division of Geological and Planetary Sciences, California Institute of Technology
More than 90% of the energy trapped on Earth by increasingly abundant greenhouse gases is absorbed by the ocean. Monitoring the resulting ocean warming remains a challenging sampling problem. To...

Craig H. Bishop - School of Earth Sciences and ARC Centre of Excellence for Climate Extremes, University of Melbourne
Current state estimation or data assimilation techniques assume Gaussian uncertainties for both forecasts and observations. However, unbiased observations of bounded variables can be shown to have...

Sean Gasiorek - University of Sydney
We give a review of Euclidean and pseudo-Euclidean billiards in the plane and in d-dimensional space. If the billiard table is bounded by confocal quadrics, periodic trajectories can be expressed in...

Matthew Tam - University of Melbourne
Generative adversarial networks (GANs) are an approach to fitting generative models over complex structured spaces. Within this framework, the fitting problem is posed as a zero-sum game between two...

Lindon Roberts - Australian National University
Least-squares problems (such as parameter estimation) are ubiquitous across quantitative disciplines. Optimisation algorithms for solving such problems are numerous and well-established. However, in...

Ian Lizarraga - University of Sydney
Recent work on multiple-timescale dynamical systems has overwhelmingly focused on models where there is a global identification of “slow” versus “fast” variables throughout the phase space. But in...

Emeritus Professor Colin Rogers - UNSW
The combined action of reciprocal and integral-type transformations is here used to sequentially reduce to canonical form a class of nonlinear moving boundary problems involving heterogeneity....

Ilknur Tulunay - UNSW School of Maths and Stats
ST-metric, arising from relative entropy can be thought as the distance between two discrete curves in the unit interval. Any data set can also be viewed as a discrete curve and can be transformed...

 Abhishek Bhardwaj - ANU
 Non-negative polynomials are fundamental objects of study in real algebraic geometry. Testing the non-negativity of polynomials is known to be NP hard. Because of this, one generally looks to...

Benoît Pasquier - Department of Earth System Science of the University of California
 Steady-state systems of nonlinear partial differential equations (PDEs) are common in engineering and the biogeosciences. These systems are typically controlled by parameters that can be estimated...
