About

I am currently a Data & AI Researcher at Intesa Sanpaolo, where I continue my work that started at CENTAI Institute in Turin, Italy. Before joining CENTAI, I worked as a Postdoctoral Researcher at RIKEN Center for Advanced Intelligence Project (2017–2020), and then as a Research Associate at the University of Tokyo, Department of Mathematical Informatics (2020–2022). I received my Doctor of Engineering (equivalent to a Ph.D.) from Tokyo Institute of Technology in 2017.

Research

Graphs are a powerful abstraction for representing complex relational data, appearing in a wide range of domains such as social networks, protein–protein interactions, and the structure of the Web. My primary research lies at the intersection of data mining and mathematical optimization, with a focus on graph mining—developing principled and scalable methodologies to extract meaningful and actionable knowledge from networks. In my work, I have proposed novel optimization models in graph mining tailored to real-world challenges, especially in AI for social good, and designed algorithms with provable quality guarantees, grounded in the theory of mathematical optimization. Such theoretical guarantees are not only essential for ensuring algorithmic reliability but also serve as a rigorous foundation for systematically comparing methods, thereby contributing to the conceptual unification and advancement of the field.
