Coordinator of the POEMA consortium: Bernard Mourrain (email@example.com)
Site leader at CWI: Monique Laurent (M.Laurent@cwi.nl)
The consortium POEMA consists of 14 partners in six European countries, inclusing CWI, Amsterdam, and Tilburg University in the Netherlands, and 3 associate partners. See also Cordis for details.
The consortium has 15 PhD positions in total. Among them there are two PhD positions available at CWI from September 2019. Descriptions of these two positions can be found below:
(ESR 6) Approximation hierarchies for (non-)commutative polynomial optimization
The position ESR6 is now filled.
(ESR 7) Approximation hierarchies for graph parameters
The position ESR7 is now filled.
Please see the call for applications at the CWI webpage. Follow the directions there as to the documents needed for your application.
For information about these two positions please contact Monique Laurent.
The positions are available from fall 2019, and should start latest 1 Jaunaury 2020. Interested candidates should apply asap.
