Antoine Joux, Faculty

I am looking for candidates that have a strong background in Mathematics or theoretical Computer Science. Knowledge of cryptology would be a plus.

The application should specify (and justify) the specific domain of interest of the candidate.

In the context of the Almacrypt ERC, CISPA has several phD positions related to the study of cryptographic hard problems. The proposed topics are discrete logarithms and factoring, lattice reduction, multivariate equation systems, elliptic curves and combinarial problems of cryptographic relevance.


Qualified candidates who wish to pursue a doctoral degree in a research area covered by CISPA faculty may apply at any time. We will accept applications throughout the year for exceptionally strong candidates. Admitted applicants will have an opportunity to visit the center and its partner institutions and interact with faculty and students before making their decision. Admitted students are advised by CISPA faculty.

The center is committed to increasing the representation of women, minorities, and individuals with disabilities in Computer Science. In accordance with the Equal Opportunity Plan, the institute aims at increasing the number of women in Computer Science, and explicitly encourages women to apply. Applications of severely disabled candidates with equivalent qualifications will be given priority.
