[Opt-Net] PhD student position (f/m/d) on Stochastic gradient methods for almost sure state constraints for optimal control of gas flow under uncertainty (Ref. 22/29) at WIAS, Berlin, Germany

[Heike Sill]

WIAS invites applications for a

PhD student position (f/m/d)

(Ref. 22/29)

in the Research Group

“Nonsmooth Variational Problems and Operator Equations”

(Head: Prof. Dr. M. Hintermüller) starting at July 1, 2022.

The position is tied to project:

“Stochastic gradient methods for almost sure state constraints for 
optimal control of gas flow under uncertainty”,

a subproject of the collaborative research center TRR 154: Mathematical 
Modeling, Simulation and Optimization Using the Example of Gas Networks. 
The collaborative research center is an interdisciplinary endeavor 
between the Weierstrass Institute, Humboldt Universityof Berlin, 
Technical University ofBerlin, Technical University of Darmstadt, and 
Friedrich-Alexander University in Erlangen Nuremberg.

The goal of this project is the development of stochastic gradient 
methods for the treatment of almost sure state constraints. Such 
constraints arise for example in the nomination validation of gas 
networks under uncertain demands but also play a role in the transition 
towards future hydrogen networks. A focus of the project is the 
consideration of sequences of relaxed problems intertwined with the 
stochastic gradient method and a rigorous mathematical convergence 
analysis of the resulting methods.

We are looking for candidates with a master’s degree in mathematics or a 
closely related field with a strong background in optimization and 
partial differential equations. Prior knowledge in stochastic 
optimization, optimal control, or stochastic analysis is beneficial.

Please direct scientific queries to Prof. Dr. M. Hintermüeller 
(Michael.Hintermueller at wias-berlin.de 
<mailto:michael.hintermueller at wias-berlin.de?subject=22-11>).

The appointment is limited until 30.06.2026. The reduced work schedule 
is 29.25 hours per week, and the salary is according to the German TVoeD 
Bund scale.

The Weierstrass Institute is an equal opportunity employer. We 
explicitly encourage female researchers to apply for the offered 
position. Among equally qualified applicants, disabled candidates will 
be given preference.

Please apply here on the TRR 154 website 
<https://www.trr154.fau.de/stellenangebote/> and select sub-project C08.

We are looking forward to your application!
