Dr Pavel Krivitsky - University of Wollongong
Egocentric network sampling observes the network of interest from the point of view of a set of sampled actors, who provide information about themselves and anonymized information on their network...

Randell Heyman - UNSW
The approximate GCD problem seeks to efficiently determine the GCD of a set of numbers.We do not know most or all of the numbers; rather we are given numbers that lie close by.As well as discussing...

Prof. Mary Myerscough - The University of Sydney
Why do some people develop cardiovascular disease while others with similar risk profiles do not? What causes plaques to regress? Why does raising HDL (“good cholesterol”) reduce cardiovascular...

Guoyin Li - University of New South Wales
Optimization problems involving polynomial functions are of great importance in applied mathematics and engineering, and they are intrinsically hard problems. They arise in important engineering...

Dr Peter Exterkate - University of Sydney
Kernel ridge regression is a technique to perform ridge regression with a potentially infinite number of nonlinear transformations of the independent variables as regressors. This makes it a powerful...

Anna Tomskova - UNSW
Let M be a von Neumann algebra and let (L_p(M), ||.||_p), 1<=p<infinity be Haagerup's L_p-space on M. It is proved that the differentiability properties of ||.||_p are precisely the same as...

Hendrik Grundling - UNSW
We  consider  group  actions a:G->A  of  topological  groups on C*-algebras A of the type which occur in many quantum physics models.  These are singular actions in the sense that they need not be...

Edward McDonald - School of Mathematics and Statistics
In 1994 Alain Connes introduced a quantised" calculus, based on operator theoretic expressions which play roles analogous to derivatives and differentials in ordinary calculus. Quantised calculus...

Dr Anbupalam Thalamuthu, Assoc/Prof Wei Wen - Centre for Healthy Brain Ageing (CHeBA), School of Psychiatry, UNSW Medicine
CHeBA aims to conduct multidisciplinary research into ageing in health and disease, and be involved in knowledge dissemination and translational research. See http://cheba.unsw.edu.au/ for details....

Prof. Mark Freidlin - University of Maryland
Long time behavior of a dynamical system, evolutionary PDE, or a stochastic process, under certain assumptions, can be described by the invariant measure corresponding to the initial condition...
