Who am I?I am a mathematician. My research interests include Ramsey theory, model theory, universal algebra, theoretical computer science.In this very moment, I am probably at one of the following institutions:

NewsI will attend the Hausdorff trimester programme Universality and Homogeneity held at the Hausdorff Research Institute for Mathematics, Bonn, from September 2013 to December 2013 [poster pdf]. Future talks:
The Ordener Lectures, a workshop on logic, universal algebra, Ramsey theory and constraint satisfaction took place in rue ordener, Paris on October 4&5, 2012. Proceedings available soon! These are slides of some recent talks of mine. All slides of all talks ever can be found further down the page. |
PublicationsA pdf of my list of publications is available here.
Preprints of most publications can also be downloaded from the arXiv.org archive. |
