I am professor of discrete mathematics at SUPSI (working within DTI, IDSIA and DFA), a lecturer at Fernuni Schweiz and a visiting fellow at University of Pisa.
My research interests are at the crossroads of combinatorics, topology and algebra, with a view on developing discrete structures for problems in pure and applied mathematics. Other interests include mathematics education at all school levels. .
