[[img img/applications-science.png link="no" class="flow" alt="science"]] My main job is doing research (and [[teaching]]) at the [Department of Computer Science](http://www.cs.unibo.it) of the [University of Bologna](http://www.unibo.it). My current and not-so current research interests are summarized below, a list of my **[[publications]]** on available in a [[separate_page|publications]]. # research interests * type theory and in particular **proof assistants** / interactive theorem provers. I've been one of the architect of the [Matita proof assistant](http://matita.cs.unibo.it), though now I'm contributing code more sparingly; both my master and Ph.D. [[theses|publications]] have been about Matita. I've also worked on distributed digital libraries of formalized mathematics, such as the [HELM](http://helm.cs.unibo.it) library * **web technologies**, in particular: type systems for typing XML trees (I'm currently a member of [W3C](http://www.w3.org)'s [XML Schema working group](http://www.w3.org/XML/Schema)) and document validation, overlapping markup, web collaboration (as in [[wikipedia wiki]]s) and its interaction with content constraints * **free software**, in particular software engineering applications to wide software repositories (the typical use case of GNU/Linux distributions) and the application of formal methods to them to various ends (for example for dependency handling)
