Computeralgebra

I am involved in the directory of the number theoretic computer algebra system Kant and its shell KASH (see the Kant project) that are developed at TU Berlin. Kant is also available through Magma.

I serve as a member on the steering committee of the Fachgruppe Computeralgebra of GI/DMV/GAMM.

I serve as a member on the steering committee of the Fachgruppe Kryptologie of GI.

I am the team leader of the Berlin branch of the EU funded project SCIEnce with eight european partners.

European Network of Excellence in Cryptography

I am an associate member of the EU funded Network of Excellence ECRYPT 2.
