4th IMA Conference on Nonlinearity and Coherent Structures
7- 9 July, 2021, Online Conference via Zoom Webinar

Nonlinearity plays an important role in many fields of Science,
Engineering and Technology. The aim of this conference is to bring
together researchers working on aspects of nonlinear phenomena and to
encourage interaction between experts from different areas such as
Applied Mathematics, Mathematical Analysis, Fluid Dynamics,
Engineering and Physics. Recent theoretical developments, new
computational methods and experimental findings will be presented and
discussed. We plan to avoid parallel sessions and foster as much as
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
Posters Presentations on the basis of a 200-300 word abstract until 16
June 2021. If you would like to submit a Poster please email the IMA
Conferences Department with your submission.

We are happy to announce that the CEMRACS 2021 on "Data Assimilation
and Reduced Modeling for High Dimensional Problems" will eventually
take place from Jul 19 to Aug 27, 2021, and registration is now
open. All details available here

CEMRACS is a summer program aiming at bringing together scientists
from both the academic and industrial communities to work on and
discuss focused topics. The program includes a one-week summer school
followed by 5 weeks of research sessions on projects proposed by
academic and industrial partners. Participants may register to the
summer school only or to the entire program.

The summer school will be proposed in hybrid format, with participants
on-site at CIRM (Luminy, France) as well as online. Due to sanitary
restrictions, the number of places on-site is limited. Confirmed
speakers of the summer school (Jul 19-23) are Albert Cohen, Masoumeh
Dashti, Eric Moulines, Anthony Nouy, Claudia Schillings, Johannes

Registration is available here

The 5 weeks research stay is fully on site at CIRM, Luminy. Interested
students should apply here by June 19th,
2021. The number of slots for participation in the projects is very
limited, but few slots are still available.

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.
