Dario Fasino is an Associate Professor in Numerical Analysis in the Department of Mathematics, Computer Science and Physics of the University of Udine, Italy. The majority of his work concerns spectral properties and computational properties of structured matrices arising in a variety of subjects. His most current research interests lie at the interface of network science and numerical linear algebra. Around 2000, he started a fruitful collaboration with D. Freni in semihypergroup and hypergroup theory.
