I am an editor for the Bulletin of Symbolic Logic. I invite the submission of carefully worked survey articles or research articles.
I am also an editor for the Annals of Pure and Applied Logic. I invite submissions, at a level comparable to the level of the JSL.
1) Computability theory.
In earlier papers (1994-2003) I have investigated degree structures using model theoretic methods.
See my habilitation thesis Coding
Methods in computability theory and complexity theory for a summary.
2002-2013 I have studied the interplay of computability and randomness. For an overview of work up to 2010 see
Interactions of Computability and Randomness, Proceedings of the International Congress of Mathematicians, 2010. For details see my
My recent interests include the connection of randomness to set theory, and reverse mathematics.
I also work on invariant descriptive set theory, in particular for Polish metric spaces.
2) Algebra and automatic structures.
I apply logical methods especially to groups, and study structures that can be described
by automata, or via Borel relations.
See my survey papers:
Describing Groups. Bull. Symb. Logic. 13 no 3 (2007), 305-339
Borel Structures: a brief survey   (with A. Montalban). To appear in Effective Mathematics of the Uncountable (EMU), Oct. 2013.
