About me
I'm a second-year PhD candidate in Artificial Intelligence at the University of Pisa (UniPi) and at the High Performance Computing laboratory (HPC lab), part of the Institute of Information Science & Technologies (ISTI) of Italy's National Research Council (CNR).
My research interests lie mostly at the intersection of Machine Learning and Network Science. My current project, under the supervision of Dr. Emanuele Carlini and Dr. Salvatore Trani, focuses at the node-level clustering of attributed temporal graphs.
Prior to the PhD, I completed a B.S. in Communication (UFES, 2018), a postgraduate in Data Science (IFES, 2021), and an M.S. in Social Science (UFES, 2022), with a thesis on text-based classification of communities applied to the study of online social networks.
Research interests
- Artificial Intelligence: deep learning, graph neural networks, self-organizing maps.
- Network Science: cascades, community detection, dynamic graphs, hypergraphs.
- Social Network Analysis: controversy mapping, social network dynamics.
