I am an Associate Professor of Geometry and Algebra at Dept. of Mathematics and Applications "R. Caccioppoli" of University of Naples "Federico II". I hold a M.Sc. (2001) and a Ph.D. (2007) in Mathematics from University of Messina (Italy). I have been a Visiting Professor at FAMNIT of University of Primorska in Slovenia (2014).

My research interest is in **Discrete Mathematics**, especially Graph Theory. My favourite topics are *Spectral Graph Theory, Combinatorial Matrix Theory*, and *Applications of Graphs in Computers Science and Chemistry.*
