Research
My research lies in the broad area of measured group theory. A common thread in my research is understanding measured-combinatorial generalizations of group properties. How can we use analysis, combinatorics, and geometry to understand infinite groups through their dynamics?
My favourite open problem is the Aldous-Lyons conjecture, which generalizes to graphings the Sofic problem for groups.
Some keywords for my interests include (but are not limited to) approximability, Borel combinatorics, Borel equivalence relations, cost, graphings, l_2-Betti numbers, property (T), soficity, treeability and unimodular random graphs.
