Research interests

My current research interests are graph drawing and the generation of maps and diagrams.

During my stay at the UofA, I was part of the Gama Group (Graph and Maps Algorithms), supervised by Stephen Kobourov. I was also working on a ONR (Office of Naval Research) project for the development of a security visualisation software.

Ocotillo is a java-based graph drawing library. The library is meant to be self-contained, highly portable and easy to use. The library is distributed according to the Apache licence. It is, however, at a very early stage of development.


EulerSmooth is a technique to smooth the contours of existing Euler diagrams in order to make them more readable. This software demo is based on the ocotillo library and can be executed by unpacking the zipped folder and running the jar contained.


More about me...

I am Italian from Bassano del Grappa, a small pretty town by the feet of Mount Grappa. You might know Bassano for white asparagus, Grappa, or just because it has been an important theatre during the World Wars. If you are going to visit Venezia, Padova or Verona, you may think to have a look even at my town! As a last geographical note for art lovers, the birth town of Antonio Canova is not that far as well. You can have a look to the "Museo Canoviano" and to another beautiful village, Asolo.

In 2005 I went to Glasgow as an Erasmus student. Since then, I have had many reasons to visit Scotland regularly. A few of them are the Highlands, Ceilidh dancing and of course Whisky.

In Bordeaux, I had the pleasure to discover many wonders of France. There are things that do not need a presentation, like la cuisine française or the Bordeaux wine, while others might be less known. I will just mention the wonderful city of Saint-Émilion, a UNESCO World Heritage Site that is just few kilometres east of Bordeaux.

For a couple of years I lived in Tucson, surrounded by the wonderful Sonoran desert. Then, Europe called me back.
