2019-10: Together with Amelia Johns and Fracesco Bailo, I was awarded a prestigious Facebook grant on Using computational modelling of user behaviour and machine learning to counter the diffusion of hate speech across social media.
2019-10: I wrote a piece for the influential media outlet The Conversation entitled Can hiding likes make Facebook fairer and rein in fake news? The science says maybe, which received significant attention on social media (Twitter & LinkedIn), from the FEIT and UTS media departments. Subsequently, I was interviewed on the radio about the work and the phenomenon.

2018-03: Three of our papers just got accepted at ICWSM 2018, the top computational social science conference.
Rendez-vous in Stanford, California, US.
2018-01: Our slick-looking HIPie popularity explorer tool will be showcased at the WWW 2018 conference in Lyon, France.
Check out it's video tutorial, Github repository and live installation.
2017-12: Our paper "SIR-Hawkes: on the Relationship Between Epidemic Models and Hawkes Point Processes" has just been accepted at the
WWW 2018 conference in Lyon, France!
2016-05-03: Check out our brand new Computational Media lab page.

WSDM 2016 conference in San Francisco!
2015-09: Our paper "ClusPath: A Temporal-driven Clustering to Infer Typical Evolution Paths" has been accepted for publication with the journal of
Data Mining and Knowledge Discovery
This year 2015, I give lectures about Machine Learning and Social Media and Sentiment Analysis in the context of the
Document Analysis course,
with the Research School of Computer Science at the ANU.
Since May 2014, I am at the NICTA lab, Canberra, Australia, as a researcher,
working with Manuel Cebrian, Lexing Xie
and Pascal Van Hentenryck.
Starting from May 2014, I will be at the NICTA lab, Canberra, Australia, in a research visit and I will
be working with Manuel Cebrian and
Pascal Van Hentenryck.
On the 24th of June, I defended my PhD thesis, entitled "Semi-Supervised Structuring of Complex Data", and I obtained
the title of PhD from the University Lumière Lyon 2. The thesis manuscript is available here.
In July, I will be at the NICTA lab, Australia, in a research visit and I will
be working with Tiberio Caetano.
