Work experience

# PhD candidate (Graduate Fellowship) at Northeastern University, Khoury College of Computer Sciences, Data Visualization Lab
Focus on temporal event sequence visualization and graph layout algorithms.
Boston, September 2018 - now

# Research Assistant at Department of Computer, Control and Management Engineering, La Sapienza University of Rome, Knowledge Representation and Semantic Technologies Lab
I worked on SPARQLING, a tool to allow a graphical representation of a SPARQL query over an ontology, and to allow building queries by interacting with a graphical representation of the ontology.

# Codemotion Kids, role: Teacher
March 2015 - September 2017
I taught the basics of coding to children aged 7 to 17, by using games and creativity in an educational way.
The courses I taught used Scratch, Blender, Arduino, Minecraft, Processing, Python, Lego Mindstorms.
I designed several of the courses, trained other teachers and produced games and applications for kids for various events by Codemotion.

Awards, talks and exhibitions

# Awarded with Excellence Path at Sapienza University of Rome
January 2018

# Speaker at Machine Learning/Data Science Meetup Roma, talk: "Raiders of the lost reviews" [notebook/slides]
December 2017

# Speaker at Linux Day Rome 2017, talk: "Let there be light: Introduction to GLSL" [slides]
October 2017
Computer graphics is not only a field for artists: math and coding are fundamental in the steps between the creation of a 3D model and its visual representation. GLSL is a programming language to instruct the graphics card on how to represent a 3D scene. Understanding GLSL lets us create renderings as we want them. During the workshop, we will explore the details of the rendering process, understand what is a shader and how it works, and we will write one to render a 3D scene.

# Speaker at Google Developer Groups DevFest Bari 2017, talk: "You Turing Complete Me", a lesson about Turing completeness in videogames. [slides]
October 2017

# Speaker at Campus Party 2017, talk: "You Turing Complete Me", a lesson about Turing completeness in videogames. [slides]
Turing Completeness is a set of characteristics that makes any language able to be used to build a Turing machine, therefore to be used to write any program or define another programming language. Such characteristics are so simple that they can be found in unexpected places like videogames. ”You Turing Complete Me” is a talk that explores weird Turing Complete places, including Pokémon and Minecraft.
