Scientific Machine Learning - Semester Programme

My group has been organising a very successful CWI Semester Programme on Scientific Machine Learning.  You can find most of the material here. Here’s a quick overview of our main events:

Autumn School, October 9-13

Introducing PhD students, postdocs and other early career researchers to SciML, with lectures and hands-on tutorials on topics like reduced-order models, neural ODEs, and data-driven multi-scale methods. World experts like Steve Brunton and Hod Lipson are giving their lectures in Amsterdam.

Industry & Society, November 23

Bridging theory and practice, with SciML from a practical and industrial point of view, with speakers from KNMI and Deltares, amongst others. (More information here.)

Workshop, December 6-8

Connecting Dutch researchers who are interested in SciML to the international community. We have a stellar line-up with speakers like Jan Hesthaven, Sid Mishra and Dirk Hartmann. (Click here for details.)

Seminar++: throughout the program

In October, November and December, renowned international researchers will visit CWI for several days in order to present, discuss and interact on open problems in SciML with the Dutch community. The seminars can be followed online as well. (More information here)

Towards truly predictive computational science

The future of computational science lies in the combination of physical modelling and data-driven techniques. In my research group at CWI, the Scientific Computing group, we develop new methods and algorithms that enable the transition to truly predictive models. For this purpose, we work at the intersection of different disciplines: uncertainty quantification, partial differential equations and discretization methods, computational fluid dynamics, machine learning, reduced-order modeling, and Bayesian inference.

The models that we develop are applied to a variety of (industrial) applications: for example, sloshing of liquid natural gas in tanker ships, aeroelastic predictions for wind turbines, and transport of multiphase flow in pipelines. Our work also forms an enabler for recent techniques such as Digital Twins.
