She is a recipient of the IEEE Computer Society Golden Core award and she is an inducted member of the IEEE Honor Society IEEE Eta Kappa Nu.

She has been the editor-in-chief of the IEEE Transactions on Visualization and Computer Graphics (TVCG) from 2015-2018, and served as an associate editor for IEEE TVCG from 2004 to 2008. De Floriani is currently an editor of ACM Transactions on Spatial Algorithms and Systems, Computers & Graphics, Computer Science Review, GeoInformatica, Graphical Models, ISPRS International Journal of Geo-Information and International Journal of Spatial Information Science. She has served on the program committees of over 150 leading international conferences, contributing in several conferences in a leadership capacity.

De Floriani has authored over 300 peer-reviewed scientific publications in data visualization, spatial data representation and processing, computer graphics, geometric modeling, shape analysis and understanding, garnering several best paper awards and invitations as a keynote speaker. Her research has been funded by numerous national and international agencies, including the European Commission and the National Science Foundation.
