possible communication across the different communities.  Please note
all talks will be recorded and available shortly after the event for
everyone who had paid and registered for the conference and will be
available for one month after.

Conference topics: Integrable systems and soliton theory; Nonlinear
waves and nonlinear evolution equations; Dispersive hydrodynamics;
Rogue waves and extreme wave phenomena; Instabilities in nonlinear
media; Coherent structures and turbulence; Nonlinear phenomena in
physical and biological sciences; Phenomena at the interface of
nonlinear waves and machine learning.

Our Oral Presentation submission is now closed.  We are accepting

Faculty Position, Numerical Methods for Large-Scale Inverse Problems
and Data Assimilation, KU Leuven, Belgium

The research unit NUMA, Department of Computer Science, invites
applications for a full-time faculty position. The unit covers many
aspects of numerics, incl. approximation theory, numerical
integration, numerical (multi)linear algebra, numerical PDEs,
uncertainty quantification, optimization and control, discrete
optimization and scheduling, data science, HPC and applied numerical
mathematics.  The recent surge in advanced techniques for data
acquisition gives rise to computational tasks of a complexity beyond
numerical simulation as integrating measurement data in complex models
requires specific numerical algorithms. In the simplest setting,
finding the "best" model parameters given some measurement data is an
optimization problem. However, demands of practical applications often
go far beyond this optimization: one can, for instance, also be
interested in quantifying the uncertainty on the resulting optimum,
the remaining modeling error with respect to the physical system, or
the evolution of the model as a function of time.  The new faculty
position aims to strengthen NUMA's position in scientific computing
towards a data rich environment. The successful candidate is expected
to develop a research program in inverse problems and data
assimilation, ensure high-quality education within the area of
mathematical engineering, and be prepared to provide scientific,
social and administrative services.
