Since 2002 I have studied the interplay of

For an overview of work up to 2010 see Interactions of Computability and Randomness, Proceedings of the International Congress of Mathematicians, 2010.

For recent work see e.g. Coherent randomness tests and computing the K-trivial sets. With L. Bienvenu, N. Greenberg, A. Kucera, and D. Turetsky. J. European Math. Society 18 (2016), 773-812.

My recent interests include the connection of randomness to

I apply logical methods to algebraic structures, especially to groups. A recent paper in this direction: Describing finite groups by short first-order sentences. With Katrin Tent. Israel J. Mathematics, to appear.

I haved studied structures that can be described by

In earlier papers (1994-2003) I have investigated
