includes (but is not limited to)
* the exploitation of dissipative and port-Hamiltonian system
structures in control simulation and optimization of dissipative
systems,
* energy-based modeling concepts,
* structure-preserving model reduction methods, and
* data-driven control methods.
The registration platform is now open and can be accessed via
https://unidistance.ch/en/mathematics-and-computer-science/event/3rd-brig-workshop-on-dissipativity-in-systems-and-control
The deadline for abstract submission and registration are February 15

Subject: Postdoc position in ML-based ocean state estimation, UC San Diego, USA
The Environmental Fluid Dynamics Lab in the Department of Mechanical
and Aerospace Engineering at UCSD invites applications for a
postdoctoral fellowship funded by the Gordon and Betty Moore
Foundation focused on the topic of machine learning-based ocean state
estimation to begin in Spring/Summer 2026. The successful applicant
will develop and implement data-driven tools, underpinned by
scientific machine learning and reduced- order modeling, for ocean
state estimation with quantified uncertainties. The central aim is to
increase the efficiency and accuracy of near-field prediction of
physical and biological conditions for marine operations including
marine carbon dioxide removal (mCDR) and aquaculture. The ideal
candidate will have experience in two or three of the focal areas:
data driven modeling, scientific machine learning or coastal ocean
physics; and will have an interest in applying these towards ocean
applications.
The postdoc will work directly with Dr. Geno Pawlak Tejada, Dr. Boris
Kramer and Dr. Oliver Schmidt at the Department of Mechanical and
Aerospace Engineering and will also collaborate with co-investigators
at Stanford University.
