TitleOptimal control of a dynamo flow
CategoryPostDoc Position
LocationFrance, Nice
InternationalYes, international applications are welcome
Closure Date* None *
We are hiring an ANR funded postdoctoral research assistant at INRIA in Nice, France, to work on optimal 
control and nonlinear stability of MHD flows (more details below).

The postdoc will join the Laboratoire J.A. Dieudonné, located in Parc Valrose (Université Nice Sophia-
Antipolis) on the French Riviera. The campus is in the city-center, at walking distance from the sea and short 
driving distance from the mountains.

Please share this with any recent PhD or postdoc who might be interested.

The considerable diversity of long-lived magnetic fields observed in the Universe raises fundamental 
questions regarding their origin. Although it is now widely accepted that such fields are sustained by a 
dynamo instability in the electrically conducting fluid layers of celestial bodies, understanding the conditions 
of nonlinear excitation and saturation of a dynamo instability in a swirling MHD flow remains an important 
challenge for the modeling of astrophysical magnetic fields.

The project aims at developing the numerical tools required to achieve fully nonlinear optimal control of MHD 
flows. These tools will be used to identify "minimal dynamo seeds" in simple swirling flows relevant to stellar 
systems, i.e. challenge the stability of such flows with respect to initial magnetic fields of arbitrary amplitude 
and structure. Furthermore, nonlinear optimisation will be used as a physical diagnostic to gain novel 
understanding of the mechanisms that are most favorable to dynamo action in astrophysical systems. Original 
ideas and suggestions from the postdoctoral researcher will be encouraged.

The position requires a PhD in applied maths, fluid mechanics or related field, and is available from 
September, 1st. It requires strong background in numerical methods for EDP. Funding is already secured for 
two years (one-year position renewable once). Applications will be accepted until the position is filled, 
preferably before July, 10th.
Interested candidates are welcome to contact me ( for more informations.
