I am a Researcher at NICTA's Canberra Research Lab. I am a member of the Optimisation Research Group (ORG), working on Logistics, Supply Chains, and Transportation.

I attained my Ph.D. in Industrial and Information Engineering on April 4, 2014, at the University of Udine. My main research interests are propagation-based hybrid meta-heuristics for combinatorial optimization and intelligent parameter tuning, mainly applied to transportation and computational sustainability problems.

Virtual camera control

Even if, strictly speaking, it has never been published anywhere, my M.Sc. thesis (English) is about virtual camera control. I also authored a paper on the topic

Ph.D. Thesis

In December, 2013 I submitted my Ph.D. thesis for approval. Here is the pre-print version (March, 2014).

Other activities

I am also involved in various activities related to the academic world

Teaching

In September 2013 I gave an invited talk about virtual camera control for the course of Computer Graphics Programming at the Aalborg University of Copenhagen (taught by Dr. Paolo Burelli) | Slides.

I used to give some extra lectures (e.g. laboratory hours) for courses at the Faculty of Engineering. Here are some slides about practical network and system attacks I gave in 2011 for the Computer security course by Prof. Pier Luca Montessoro.

Note: all the slides are in Italian.

I used to give some extra lectures for the course of Web Applications, by Dr. Luca Di Gaspero
