Ariadna Fosch
Ph.D Student
arikacibofoscvani9hh@gmail.com

Ariadna Fosch obtained her Bachelor’s in Biomedical Engineering from the Pomeu Fabra University in 2019, and a MSc in Systems Biology from the Maastricht University in 2021. Now she is a PhD student at Cosnet BIFI, under the co-supervision of Yamir Moreno and Alberto Aletá. Her research focuses on applying complex systems methods to the management of different societal challenges. More specifically, she aims to provide data-driven methods to aid policymakers in managing crises, like the Covid-19 pandemic, or designing sustainable policies against climate change. While pursuing her PhD, she worked as a Junior Researcher at the Institute for Scientific Interchange (ISI) and the CENTAI Institute, both based in Turin, Italy. She also contributed to the writing of an IUCN report, helped organise several conferences, and remains actively engaged in the complexity science community. She serves on the steering committee of the Winter Workshop on Complex Systems and is a founding member of Complexity and Networks Community and Resources (CORE).

pietro.haralutraversacenjeons98@gmail.com
Pietro Traversa obtained his bachelor’s degree in physical engineering at the Politecnico of Torino in 2020 and his MSc in Physics of Complex Systems in 2022 from the universities of Politecnico of Torino, Sorbonne University, Paris Saclay, and Paris Cité. His research focuses on the study of hypergraphs and how to use them to model real systems, such as metabolic networks, and higher-order dynamical processes, such as contagion and rumor dynamics. For two years of his PhD, he was employed as a Junior Researcher at the CENTAI Institute, Turin, Italy. He also took part in the KATY European project, focusing on studying the properties of gene co-expression networks of patients. For this project, he collaborated with and visited the CEA lab in Grenoble.

JunFeng Fan studied at Inner Mongolia University of Technology(China) from 2008 to 2012 and received the BS in Engineering. From 2014 to 2017, he worked as a programmer at Beijing SouFun Science&Technology Development Co.,Ltd. Then, he studied at Tianjin University of Technology (China) from 2020 to 2022 and obtained the MS in Engineering. Now he is a Ph.D. student at Cosnet Lab, BIFI, who are supported by the China Scholarship Council. He is interested in coupled spreading dynamics between epidemics and awareness on multiplex, higher-order interaction, human behavioural changes, complex networks modelling and analysis.

I completed my undergraduate and Master’s degrees in Physics at the University of Zaragoza in July 2023 and July 2024, respectively. My research interests span a wide range of topics, from uncovering insights into coarse-graining methods to studying social behaviors in cows, as well as exploring economic systems. I am currently pursuing my PhD, “Unraveling Complexity through AI in Data-Rich Systems,” under the supervision of Alberto Aleta and Yamir Moreno, with funding from a DGA grant. As part of my academic journey, I have participated in conferences such as “Theoretical Challenges in Network Science” in Seoul and attended the school “Complex Networks: Theory, Methods, and Applications” in Como.

My name is Cyril Jean Charles Rommens, a PhD student in the EU-funded doctoral network ‘BeyondTheEdge’ at the Complex Systems and Networks Laboratory (COSNET), Institute for Biocomputation and Physics of Complex Systems (BIFI), University of Zaragoza, Spain. I hold a MSc in Computational Physics of Complex Systems from the University of Amsterdam (2022-2024), where I focused on emergent phenomena in complex systems with a thesis on Free Energy of Simplicial Complexes in Functional Brain Networks. Simultaneously, I completed a research internship at the Bilbao Center for Applied Mathematics (2024), working with Bayesian inference, information homology, and topological data analysis of brain networks. Additionally, I hold a BSc in Physics and Astronomy and a BSc in Medical Natural Sciences from VU University Amsterdam (2017-2021), and a minor in Space Physics from The Arctic University of Norway (2022-2023). As a PhD student under Prof. Yamir Moreno at BIFI, I study the physics of high-order interactions in complex systems. My main focus is two-fold; extracting significant time- and space-like interactions in multivariate systems, and relating macroscopic structural properties to system dynamics. My interests include topics in information theory, statistical physics, and biological versus artificial intelligence.
