I am Giorgio Nicoletti, a theoretical physicist working at the interface between statistical physics, biology, and ecology, seeking universal principles that govern how living systems process information and make decisions across scales. I am currently a Postdoctoral Researcher at the Quantitative Life Sciences section of UNESCO’s International Center for Theoretical Physics, a research center supported by the IAEA and the United Nations located in Trieste, Italy.
What I work on
Information in stochastic systems
How do noisy systems harvest, propagate and pay for information?
Brains, behaviour and learning
How do neurons, brains and agents encode information and make decisions?
Spatial ecology
How do landscapes and dispersal shape the survival and coexistence of species?
Research Highlights

Tuning transduction from hidden observables to optimize information harvesting
How can we extract information on hidden signals via transduction mechanisms?

Information propagation in multilayer systems with higher-order interactions across timescales
How do timescales shape the information content of complex multiscale systems?

Landscape and environmental heterogeneity support coexistence in competitive metacommunities
How can competitive ecological communities survive in complex spatial landscapes?

Prenatal experience with language shapes the brain
How does the newborn brain respond to sounds from the maternal language?

Who I am
I obtained my PhD in Physics cum laude at the Laboratory of Interdisciplinary Physics of the University of Padova (Italy) under the supervision of Amos Maritan and Samir Suweis, with a particular focus on how the physics of phase transition and critical systems can be applied to the study of living systems. I then moved to the ECHO lab of the École Polytechnique Fédérale de Lausanne (Switzerland) for a postdoc with Andrea Rinaldo.
I was awarded the Giovanni Paladin Award during the inaugural cerimony of the 29th International Conference on Statistical Physics for the best PhD thesis in Statistical Physics. I received the Graduate Alumni Award from the University of Padova for the best graduate student in the School of Science. In 2024, I was selected by the journal Entropy as one of the outstanding reviewers of the year.
I have been a Visiting Scientist at the Okinawa Institute of Science and Technology in Onna, Japan and at the Max Planck Institute for the Physics of Complex Systems in Dresden, Germany. I was an affiliate of the Padova Neuroscience Center (Italy) and a visiting PhD student at the AI center of the University of Tübingen (Germany). I have been a member of the Complex System Society, the Italian Society of Physics, the Italian Society of Statistical Physics, and the American Physical Society.
