Research:
Mathematical logician by training, my research spans several different branches of logic, including descriptive set theory and model theory. While some early papers focused on descriptive classification theory, most of my recent work has been aimed at using tools from mathematical logic such as Ramsey theory, infinite games of perfect information and model theory to analyse objects originating in other parts of mathematics such as Banach spaces, C*-algebras, topological transformation groups and dynamical systems.
Various topics of my research are listed here with references to the publication list below indicated in [].
