Professor Luciano Pietronero has long been engaged in research on condensed matter theory, statistical physics, and complexity science, dedicated to developing verifiable quantitative theories and computational methods to understand the structure, dynamics, evolution, and prediction of complex systems across various scales. His work spans multiple fields, from nanoscale material systems to large-scale cosmic structures and socio-economic systems. Currently, he focuses on econophysics, primarily applying physical theories and methods such as statistical physics and nonlinear dynamics to study economic issues like financial markets and corporate growth.

His main research interests include:

1. Condensed Matter Theory and Unconventional Superconductivity
   Research on high-temperature superconductivity, electron-phonon interactions, nonadiabatic superconductivity, strongly correlated electronic systems, and complex Fermi-liquid behavior. A central focus is the development of many-body approaches beyond Migdal’s theorem and their applications to cuprates, fullerene compounds, MgB₂, and related materials.

2. Statistical Physics, Fractal Growth, and Self-Organized Criticality
   Research on fractal and multifractal structures, dielectric breakdown, diffusion-limited aggregation, percolation, interface growth, and sandpile models. This work includes the development of renormalization-group approaches to fractal growth and self-organized critical phenomena.

3. Complex Systems and Interdisciplinary Modelling
   Applications of statistical physics and complexity science to large-scale cosmic structures, complex networks, earthquake correlations, granular matter, information dynamics, and social systems, with emphasis on scale invariance, collective dynamics, and the emergence of complex structures.

4. Economic Fitness, Economic Complexity, and Growth Forecasting
   Development of the Fitness-Complexity framework, which uses nonlinear iterative algorithms on bipartite networks to quantify countries’ productive capabilities, product complexity, industrial competitiveness, and development potential. The framework supports data-driven analysis of GDP growth, industrial upgrading, regional innovation, economic risk, and development strategies.

5. Artificial Intelligence, Digital Economy, and Labour-Market Complexity
   Recent work extends complexity-based approaches to the impact of artificial intelligence on occupations, industries, and regional labour markets, as well as the use of machine-learning methods for forecasting industrial upgrading and economic evolution.
