Currently Assistant Professor at the Department of Cognitive Science and Artificial Intelligence (CSAI)
at Tilburg University.
Previously, I collaborated with Tooso on a project about user intent prediction on e-commerce websites. I have a Ph.D. in Computational Psycholinguistics obtained from the CLiPS Research Center of the University of Antwerp with a research focused on how children learn lexical categories (PhD thesis). Before the PhD, I got a MSc in Cognitive Science at the Center for Mind/Brain Sciences of the University of Trento using computational linguistics and computer vision to study how children build conceptual representations from words and images (MSc thesis), and a BA in Literature and Linguistics also at the University of Trento, studying conceptual representations in congenitally blind people using feature norms (BA thesis).
I worked for a while at the press office of the University of Trento and like science communication very much. I play volleyball, improvise, cook, go to concerts, watch plays, movies and series, cycle, read, listen to vinyls.

# RESEARCH INTERESTS
* Cognitive stuff: Computational models of language acquisition, Conceptual representations,
Semantics, Category learning
A bunch of interesting questions to which I'd love to find an answer:
How do children learn their native languages? What information do they rely upon? Whin learning models do the job? How do they form and represent concepts and categories? How do they understand meaning? What is the relation between language and perceptual information in creating meaning, concepts, and categories? How does what you know influence what you learn?
* Data stuff: user intent prediction, sequence modeling
Problems I'd like to collaborate on:
Deciding whether a user si going to perform a certain action on a website or not depending on how s/he interacts with the website, modeling labor market trajectories using sequence modeling and language models to learn a grammar of unemployment, identify people at risk of dropping out of school, therapies or the like using data about their interactions with teachers, doctors and so on, ...
* Stuff I'd like to do more with: brain imaging, cognitive psychology
If you're working on problems about brain imaging or cognitive psychology where my expertise in computational modeling, statistics, and data analysis may come in handy drop me a line, I'd love to be involved!
