<i>As a consequence of a concern about scientific publishing, I refuse to collaborate with certain journals. If you are contacting me for some referee work, and your journal is not green according to the criteria that are defined <a href="http://www.sherpa.ac.uk/romeo/search.php">here</a>, is edited by Elsevier, or is too expensive, chances are that I will refuse to complete it.</i>

My recent research deals with Ramsey theory, which is usually thought as a branch of combinatorics, and its interactions with topological dynamics.
