Currently I am dealing with Group Theory and some aspects of Algebraic Cryptography, focusing on the application of Group Theory and Number Theory to Symmetric Cryptography.
Since my PhD I have been interested in the following research topics:

• Permutation group methods for block cipher security [5,11,15,18,19,21,22,24,25,28,29].
• Theoretical and combinatorial aspects of Permutation groups [10,12,13,17].
• Combinatorial aspects of Integer Partitions [2,7,9].
• Group Theory and Semigroup Theory [1,14,30].
• Theoretical and combinatorial aspects of Lie algebras [3,4].
• Representations of finte-dimensional algebras [31,32,33].
• Other aspects of Algebraic Cryptography and Information Theory [6,8,16,20,23,26,27].
